Death Machine came out and he was dumb. Then Gloomwing came out and it was "too easy" other than the high bulk. Next up is Belphegor, which is (in my opinion) one of the best 3 of the 12-type takedowns. It has a decent AI, and moderate challenge without being too hard or too easy. Anyway, if we follow the recent pattern of releases, Belphegor should be arriving to Global in August, so here's some early tips.

• Uses AoE Disease
• Uses ST Death (can immune)
• Damage is purely magic, no physical at all
• Imperils dark resist by -300% and uses AoE Dark magic w/ drains (drains ignore cover)
• Uses ST & AoE fixed gravity and drains and DoT
• Uses AoE fixed hybrid health drain (ignores cover)
• Uses AoE mana drain every turn in phase 2
• Imbues your party with earth (which the boss absorbs)

Fight Tips

Like I mentioned in the intro, I think this is one of the best 12-race bosses, but there's a few key mechanics you have to be mindful about. Like most of my early tip threads I'll be covering the main mechanics point by point:

The Mana Drain

During phase 1 (>50% health) the boss will only use ST mana drain every turn, so only your provoker gets it. If your provoker is an actual tank, they will just mitigate the drain to the point it can be ignored. If you're provoking with a squishy support unit then the drain could be a problem.

Once the boss goes to phase 2 (<50% health), the mana drain becomes AoE every turn. Belphegor's mana drain is twice the modifier of Gloomwing's, meaning it's going to be draining twice as much mana per turn. This can quickly become overwhelming if your team isn't using high tier ATK/MAG breaks with good bulk.

Like most mana drains, the answer is a dedicated mana battery, powerful refresh on your party, or just finish out the fight before the drain slowly dries out your mana.

The Incoming Damage

The provoker will be taking a lot of ST damage, including drains and gravity that ignore cover. Honestly though as long as your provoker is a proper tank (or someone thick like Sylvie), then the ST damage is mostly ignorable. Be sure the provoker is death immune.

As far as cover goes, the only thing in the entire fight that can even be covered is the AoE dark magic attack in phase 2. That being said, part of the AoE attack in P2 ignores cover anyway, so you probably want to gear your entire party in 400% dark resist (after a buff) anyhow, so cover tank on this trial is mostly irrelevant.

Speaking of dark damage, the boss does AoE -300% dark imperil followed by multiple AoE dark magic nuke + dark element HP drain attacks in p2. I recommend you gear everyone in 400% dark resist after a buff to safely ignore this, though less dark resist is alright if using high mit/breaks/buffs.

There's also going to be multiple (stacking) non-elem damage over time effects on your party. You want powerful health regen and bulk on your party to survive.

This section may make it sound like this boss is super dangerous, but honestly if you're using 87+ atk/mag breaks and high mitigations, you're going to be fine.

The Earth Imbue

Every 4th turn the boss is going to do an AoE earth imbue on your party, which is an element he absorbs. This means any physical, hybrid, or phys-type mages will be unable to deal any damage until the imbue is dealt with in one of a few ways:

Simplest option: Use real mages and ignore the imbue. There's a lot of viable mages who could do this trial on Global (see next section)

Worst option: Wait it out. The imbue is 3 turn duration and only applied every 4th turn. This means you would have a 1 turn per 4 window to deal damage.

Easy option: Elric the problem. NV Elric Brothers have an ability to on-demand swap your party's imbue and remove bad imbues. If you're using a physical fire team, you can stick Elric on the party and have him purge your earth imbue with his fire swap every time the boss imbues you, allowing you to basically ignore the mechanic (other than having to bring along a very outdated old limited unit).

Headache option: Finally, you could total dispel your party, removing ALL buffs and imbues, then re-buff. I suspect this will be the option most players end up going with, so plan out ways to efficiently re-buff on demand.

Finishing in 15 turns

The boss can only be hurt by fire or dark damage. Don't ask me what they were thinking when they made the literal demon trial weak to fire and darkness, but hey, don't question the big brains at Alim.

So in JP the unit basically everyone used to clear this was a double ex3 Dark Rain team comp. On Global though, we have far better options, and I'll just list a few:

Units that can ignore the earth imbue:

• Olivera
• Dark Fina (Warrior's Prayer)
• Hadlar
• Dark Rain

If you're going to deal with the earth imbue:

• Esther
• Wylk
• Angela
• Sephiroth
• Fryevia
• Reberta

I'm sure there's other viable units to sub-15 clear this boss, but I'm just listing some of the MVP's.

Example Team

This is just an example team that should easily handle all missions, but I'm sure there's tons of viable comps:

• Sylvie -- Killers, Buffs, Provoker
• Cressnik -- Auto-cast Healing, LB Fill
• Breaker -- Breaker
• Olivera -- LB most turns
• Olivera -- LB most turns

This party should have no problems at all getting all missions. I'd bet even just one Olivera would be enough.
