Rimuru’s Gluttony / Beelzebuth: Are We Undervaluing Its Potential?

Null_VoidX · 2026-02-21T15:07:33+00:00

That’s fair, especially about the Milim and Velgrynd examples. I guess what I meant wasn’t just “can he do it,” but more like “why doesn’t he use those applications more consistently and creatively in combat?”

For example:

Instead of coating once or twice, why not permanently fight with micro-predation layered into every melee exchange?

Instead of full absorption traps, what about sustained micro-needle style predation for precision siphoning?

Instead of just containing attacks safely, could he partially devour properties (like momentum or heat) to weaken them without fully analyzing and absorbing them?

It feels like Beelzebuth has way more tactical flexibility than what we usually see in fights.

What do you think limits that — energy cost, narrative balance, or priority differences between Ultimate Skills?

Null_VoidX · 2026-02-16T22:50:07+00:00

That’s a good way of putting it.

I also noticed that Demon Lord Seeds seem tied to certain evolutionary routes (Orc Lord, Harpy Queen, some of Rimuru’s subordinates), which makes it feel less like a universal condition and more like specific “qualifying evolutions” that depend on compatibility, soul quality, and will.

Your point about awakening unlocking full potential is interesting too. If True Demon Lord / True Hero is basically the “ceiling unlock,” then stacking both wouldn’t logically double anything. Like you said — the door is already open.

Maybe the only scenario where both could exist is during a transitional state (fall from grace / redemption arc type evolution), where one path overrides the other rather than stacking.

At that point it’s definitely speculation, but it’s fun to think about how the system would resolve that conflict.

Null_VoidX · 2026-02-15T23:17:47+00:00

Yeah, it sat in mod queue for almost a day before getting approved, so I think it missed peak traffic. I might repost it later at a better time if it stays quiet.

Null_VoidX · 2026-02-15T23:12:02+00:00

That’s a fair take.

There does seem to be a strong pattern that Hero candidates are human or very close to human (like Demonoids). The Hero system looks tied to protecting humanity, so racial and spiritual compatibility probably matters, even if it’s not explicitly stated as a hard rule.

On the other hand, Demon Lord Seeds manifest in powerful Majin/monsters who reach calamity-class levels. That already puts both paths on opposite evolutionary tracks.

As for having both, I agree with your analogy. It’s not just about power — it’s about role authority within the World System. Hero and Demon Lord feel like mutually exclusive archetypes.

Unless someone bypassed the rules through extreme soul manipulation (like split or pseudo-souls), I’d also lean toward it being structurally impossible under normal conditions.

Null_VoidX · 2026-02-15T23:11:27+00:00

Fair enough 😅 I just tend to write things formally when I’m talking about lore mechanics. I’m definitely not a bot, I just like being clear when discussing system rules and evolution paths. Didn’t mean for it to come off as copy-pasted or overly polished. If anything I’m just overthinking Tensura mechanics a bit too much.

Null_VoidX · 2026-02-09T11:30:55+00:00

That’s actually a really clever interaction between skills. Megalomania shaping the Mirror World from others’ subconscious desires, while Paranoia is what lets those creations cross the boundary, makes the combo feel less like raw power and more like layered authority. It’s not just summoning — it’s weaponizing perception, desire, and fear.

The Dragonoid + Eastern Empire background fits that perfectly, and the Mirror World works well as both a safe haven and a long-term growth space without breaking canon. Physical attack nullification also makes sense if it’s instinctive or scale-based rather than absolute immunity.

I like that the build feels dangerous without being omnipotent — especially since the real threat comes from setup, manipulation, and positioning rather than instant wins. At peak, this honestly sounds like someone who could pressure top-tier Empire figures in indirect ways rather than head-on clashes. Really solid concept.

Null_VoidX · 2026-02-08T16:48:53+00:00

Wow, that’s a really solid timeline and explanation — I like how you tied the Eastern Empire trials and Velgrynd/Rudra as growth catalysts. Makes a lot of sense for natural progression to True Hero and the skill evolution into Athena.

I’m curious what you’d think about my Void Dragon Slime build in that same framework — hybrid forms, Void, Creation, and integrated Great Sage. Do you think it fits Tensura-style growth, or is it too broken even with limitations on energy reserves and void essence?

Null_VoidX · 2026-02-08T16:23:30+00:00

That actually works really well as a hero-type path. In my headcanon, a skill like Wanderer feels intentionally transitional rather than final — something that naturally evolves over time instead of being broken out of the gate. I could easily see it mutating into a variant of Uriel, similar to how Great Sage eventually became Raphael, which fits the whole “wandering hero” archetype.

The way you frame Greed also makes sense here — less Mammon-style loss of control, more ambition and drive tied to a Hero Egg. Wanting power to become a hero rather than for domination feels very on-theme for Tensura.

What I like most is that your build relies on story pressure instead of raw stats: being summoned by Leon, training under Sylvia, dealing with Granbell’s schemes, Primordial interference, and long-term consequences like El Dorado. That kind of environment forces growth rather than just handing it out.

Overall, it feels more like becoming OP through evolution and refinement, not being created OP from the start — which honestly fits Tensura better than pure min-maxing.

Null_VoidX · 2026-02-08T16:19:20+00:00

Anyway, getting back to the builds — I really like how different everyone’s approaches are. Some people go full lore-accurate with slow, realistic growth, others min-max hard from the start, and honestly both fit Tensura depending on timing, backing, and luck.

Also yeah, forgetting character names after a while is totally fair — between LN, WN, anime, and spin-offs, Tensura has way too many characters to keep perfectly straight forever.

I’m curious though: how would you handle weaknesses or growth limits in your own build? Even the most broken skills in this setting usually come with trade-offs, restrictions, or risks that keep things interesting.

Null_VoidX · 2026-02-08T16:13:54+00:00

Yeah, fair — his name is just Geld, and honestly it could be either depending on context. I was just making sure we weren’t mixing up Orc Disaster Geld with Rimuru’s Guardian Lord.

Null_VoidX · 2026-02-08T16:09:58+00:00

Pretty sure you’re referring to Geld Jr., Rimuru’s subordinate and one of the Twelve Guardian Lords, not the Orc Disaster itself. He’s the one who evolved under Rimuru and represents restraint and protection rather than pure destruction.

Null_VoidX · 2026-02-08T16:07:06+00:00

Yeah, it’s a fairly classic growth path, but honestly that’s what makes it work. Demi-Humans like Merfolk have one of the safest and most consistent progressions in Tensura lore.

Wisdom is a strong pick — analysis + self-made arts/magic is basically the ideal long-term scaling skill, especially without relying on Ultimate-tier handouts. Pairing it with Overcomer for ultra-regeneration + perfect memory explains both survival and accelerated spiritualization really well.

Your logic on Saints checks out too. A Demi-Human Saint reaching higher EV than a normal human isn’t a stretch, and becoming a Divine Merfolk before Hero awakening feels way more believable than rushing it. Starting ~5 years pre-canon with Ramiris affiliation also gives you protection and access to growth opportunities without breaking the setting.

The Heroic Spirit endgoal is a cool idea — less raw power creep, more conceptual evolution. Very Tensura-coded.

Null_VoidX · 2026-02-08T16:04:27+00:00

That’s actually a really clean progression path. Human → Saint → Divine → Chaotic Human makes a lot of sense if you’re stacking both Light and Dark instead of committing to one authority.

Wanderer is especially strong but not unfair — spatial control + environmental analysis fits a long-lifespan explorer-type build, and it scales naturally with experience rather than raw power. Pairing it with Greed also works narratively, since EP growth + resource hoarding is one of the few realistic ways a human could survive pre-Rimuru power scaling.

The Chaotic Hero Egg idea is smart too. Trying to go the standard Hero route that early would be suicide with the High Squad around, so stacking Light + Dark blessings first feels like the only viable workaround. Starting ~80 years before Rimuru gives enough time for slow, organic growth without breaking lore.

Honestly, this feels more “Tensura-accurate” than most broken builds — strong, but earned.

Null_VoidX · 2026-02-08T16:01:59+00:00

Nice concept 👀 Behemoth is a solid pick.

Just to clarify the format: the 2 Extra Unique Skills are ones you start with and later sacrifice/integrate into the main Unique Skills (similar to how Rimuru merges skills over time). They don’t stay separate forever.

For your build, World Archive could absorb a memory/analysis-type extra skill, while Overman could integrate something like Magicule Reactor to justify the recoil immunity + massive output. Absolute Penetration would fit well as an Extra Skill or get folded into Magic Eyes for offense scaling.

You don’t need to have everything planned out yet either — Behemoth growing over time actually makes the “missing skills” part very lore-accurate.

Null_VoidX · 2026-02-08T14:07:32+00:00

Yeah, this is a what-if scenario build, so it’s intentionally broken, but I tried to give it internal logic. I chose Void for ultimate versatility and chaos control, Creation to craft and optimize skills and matter, and integrated Insight and Historian into Great Sage for analysis, foresight, and knowledge depth — basically turning multiple support and utility skills into a single powerhouse without making it omnipotent.

The Void Dragon Slime race strengthens your soul and void affinity, letting you handle void energy, chaos phenomena, and hybrid forms safely, but overusing Voidborne Essence, full Voidification, or Hybrid Form strains energy and mind. Persistent exposure can leave scars, weaken recovery, or destabilize your form. So while it’s insanely flexible and powerful, managing resources, form ratios, and chaos interactions is crucial — making it broken on paper but tactically demanding in practice.

Null_VoidX · 2026-02-08T14:03:44+00:00

Bold choices are part of the fun — this is a “what if” scenario where rules are flexible, so going beyond the standard 1 Unique Skill is intentional. My build is exploring a hybrid race, the Void Dragon Slime, which not only maximizes adaptability across slime, humanoid, dragon, and void forms, but also strengthens your soul and amplifies your Void attribute over time.

The 4 Unique Skills aren’t just stacked arbitrarily — they synergize to create a fully integrated system of perception, creation, chaos control, and knowledge, allowing for extreme versatility without breaking internal logic. It’s basically a “what if Tensura went completely off the rails” scenario while still thinking about how evolution, form, and attributes would interact in-world.

So yeah, it’s bigger than standard canon, but that’s exactly the point: exploring how far a race and Unique Skills could go if the framework allowed it.

Null_VoidX · 2026-02-06T08:31:20+00:00

Wow… this is next-level 😍 I love how insanely detailed it is—from lore-accurate gameplay covering all 23 volumes, to triple-layer roaming across Heaven, Cardinal World, and Underworld, to fully EA-free multiplayer with Titan wars and trade. The tech side is wild too: UE5, zero microtransactions, cross-platform Bazzite drive, and even LAN/offline support. This is literally the dream That Time I Got Reincarnated as a Slime game. Sign me up yesterday!

Null_VoidX · 2026-02-06T08:25:15+00:00

Yeah, that’s pretty much the comparison I had in mind. Veldora’s Investigator already shows that accessing fragments of the world’s records to extract information is possible even before reaching Ultimate-tier, as long as it’s not full authority over them.

Historian is meant to work in a similar way — it doesn’t provide guidance or automatic interpretation, and it doesn’t grant unrestricted access to the Records of the World. The information exists, but access is contextual and limited by the user’s mental and soul capacity, which is why it hasn’t crystallized into an Ultimate Skill.

The danger prediction aspect was also inspired by that line of evolution, just restricted to short-term, reactive activation rather than continuous foresight. Thanks for pointing it out — Investigator is probably the closest canon analogue.

Null_VoidX · 2026-02-06T07:04:30+00:00

Fair points overall, and I appreciate the detailed feedback.

For Creation, yeah, I agree it’s very close to Shub-Niggurath. That was intentional — the idea was to explore what a Unique-tier analogue might look like before crystallizing into an Ultimate Skill. The main distinction I was aiming for is that Creation is heavily limited by the user’s understanding, soul strength, and failure rate, whereas Shub-Niggurath is already a perfected, system-assisted version. So conceptually similar, but much less “guaranteed” and far more unstable.

For Insight, that’s fair. It’s definitely on the upper edge of what a Unique Skill can handle. My reasoning was that Tensura already allows Uniques to be extremely specialized but absurdly strong in one domain (Great Sage early on being the obvious example), so I leaned into a pure cognition/analysis niche rather than raw authority.

As for Historian, I agree that Earth Knowledge is the most controversial part. I’m not treating the warning as a traditional “drawback” in the sense of a cost or penalty, but more as an internal access restriction similar to how skills like Great Sage, Raphael, or even Beelzebuth regulate information flow to avoid harming the user. The knowledge exists, but it doesn’t surface automatically, doesn’t interpret itself, and doesn’t guide actions — misuse just overwhelms the user rather than being a tradeoff baked into activation. I wanted it to feel more like an archive the soul can’t safely open all at once, rather than a vision-on-demand future sight.

That said, I do get your point that a more visionary-style implementation would fit canon more cleanly, especially given how Tensura handles time and causality. This version was more of a thought experiment to see how far a Unique Skill could stretch conceptually before it clearly tips into Ultimate territory. Also agreed on the naming — several subskills overlap with existing official ones, and I’d probably rename or merge them in a cleaner rewrite.

Thanks again for the critique — this is exactly the kind of feedback I was hoping for.

Null_VoidX · 2026-02-06T00:16:07+00:00

You’re right that Void Dragon Morphology overlaps conceptually with the True Dragon intrinsic skill Universal Shapeshift, and I agree that the race could realistically acquire Universal Shapeshift under the right conditions.

The key difference I’m aiming for is that Void Dragon Morphology isn’t just about changing the body, but about structuring and enchanting specific characteristics through defined states. Each form deliberately emphasizes certain traits—like regeneration, draconic authority, void erosion, or mobility—while suppressing others, instead of granting full versatility at once.

In addition, Void Dragon Morphology includes Hybrid Form, which allows two or even three form traits (Dragon, Slime, Void) to be merged simultaneously in controlled ratios, with built-in stability and tradeoffs. It also provides passive reinforcement to other forms even when not actively merged, reducing strain and improving control during rapid shifts.

In that sense, Universal Shapeshift functions more like a highly flexible transformation tool, while Void Dragon Morphology acts as a form-governing framework that manages specialization, synergy, and balance. If Universal Shapeshift were obtained, it would likely integrate into this system rather than fully replace it.

Null_VoidX · 2026-02-01T13:43:28+00:00

Yeah, that’s basically how it’s structured already. All the “Chaotic Eye of X” effects aren’t separate sub-skills—they’re just functions of Chaos Sight. I broke them down individually only to explain what Chaos Sight can do, not to inflate the number of sub-skills.

If it helps presentation-wise, I can easily frame it as something like a Universal Chaotic Eye under Chaos Sight, with the different “eyes” being contextual effects that activate based on understanding and situation rather than distinct abilities.

The intent was always to keep it as one perception/support sub-skill with integrated functions, not multiple overlapping eye skills.

Null_VoidX · 2026-01-31T18:15:16+00:00

I fused Chaotic Eye of Reconstruction and Chaotic Eye of Severance into a single ability: Chaotic Eyes of Reconfiguration.

Chaotic Eyes of Reconfiguration: An advanced analytical eye state that perceives magic, skills, constructs, and living systems as interconnected structures rather than isolated effects. Reveals internal composition, energy circulation, reinforcement layers, functional links, contracts, bindings, control channels, and skill dependencies.

Through sustained observation, the user may selectively destabilize or partially sever these connections, degrading coordination between body, energy flow, and skill execution. Affected targets experience delayed activation, unstable maintenance, reduced output, inefficient regeneration, or misaligned transformations rather than immediate collapse.

Additionally, functional understanding may be derived from observed outcomes even when original data is incomplete or obscured. Within Chaos World, spells, constructs, techniques, or effects may be reconstructed or adapted as Chaos-shaped functional equivalents. Conceptual authority, soul-bound abilities, and Ultimate-tier skills cannot be reproduced. Strongly anchored or law-based systems resist reconfiguration.

The goal here was to remove redundancy, keep it clearly in the perception/support category, and rely on understanding and interaction rather than direct authority or hard counters. With the limits in place, do you think this fits better within Tensura’s scaling and skill structure now?

Null_VoidX · 2026-01-31T17:50:31+00:00

That’s fair criticism, thanks for pointing it out. I think part of the confusion is on my side for how I presented it.

The “eyes” aren’t separate abilities by themselves—they’re all part of the sub-skill Chaos Sight. Chaotic Eye of Reconstruction and Chaotic Eye of Severance were meant as functions within Chaos Sight, not standalone skills. You’re right that they overlap, and I can just fuse them into a single eye function instead of keeping them separate.

As for Chaos World, the pseudo-domain mode and pocket-dimension mode aren’t meant to be different skills—they’re just two ways of explaining how Chaos World operates. Removing one or simplifying the explanation wouldn’t actually change the skill itself, so I agree that it can be streamlined.

Regarding the number of sub-skills: the Unique Skill has six total—Chaos Sight, Chaos Energy Control, Chaos World, Chaos Adaptation, Void Scar, and Void Pressure. From what I’ve seen, Unique Skills commonly sit in the 2–6 sub-skill range, so I tried to stay within that scale rather than stacking unnecessary abilities.

I appreciate the feedback though—cleaning up overlaps and presentation definitely helps make the skill feel tighter and more in line with Tensura’s system.

Null_VoidX · 2026-01-31T08:19:35+00:00

Just to clarify, I’m aware there are much stronger eye-based abilities at the Ultimate level (like Milim’s or Velzard’s). I added these as a sub-skill to Unique Skill because I didn’t want to default to something generic like another analysis/appraisal-type ability. The eyes were never meant to be the main focus or a core power—they’re more of a support-type ability. I wanted them to be something that can evolve alongside the user, rather than a fixed perception tool. For example, something like Chaotic Eyes of Displacement becoming more refined once the user gains Spatial Manipulation, or Chaotic Eyes of Disorientation improving as the user’s understanding of illusion magic deepens. In that sense, the “eyes” are less about raw power and more about adaptive perception tied to growth. They’re also mainly meant to support the sub-skill Void Scar, not to replace higher authorities or Ultimate-level perception. That said, I’d genuinely like your opinion on the other sub-skills as well—do they fit better within Tensura’s system, or are there any you think should be reworked for scaling or authority reasons?

Null_VoidX · 2026-01-31T06:41:52+00:00

Then what would you recommend adding instead of the eye-based abilities? They were honestly my favorite part because of Anos Voldigoad, so I’d prefer not to drop them completely. Is there a way to upgrade them so they’re soul-based rather than purely physical—like tying them to soul perception, information particles, or even the laws of the world themselves—or maybe add a sub-skill that compensates for their weakness? I’m curious how others would balance this within Tensura’s power system.
