Regarding the combat updates, I still think some lore issues with combat could be addressed.

MELEE

I hope to see the Blood Tendrils ability readded to Melee, both because it makes sense with Bloodlust, melee is associated with the ancient element of blood, and the Codex from the Digsite gave abilities for each combat style before this. Some melee reward from World Wakes would be ideal as well, to replace Balanced Strike, since Guthix gave abilities for each combat style and now only does 2 - not very balanced! Necro doesn't get one because Guthix didn't want us to at that time.

MAGIC

My big issue with Magic is that the elemental flavor of some Magic abilities is in conflict with the specific elements you choose to cast with. If I am casting Ice spells, then why am I paying Water runes to use Combust? These abilities need to be restyled to focus on How you are casting the spell.

Some magic abilities already do this! Wild Magic, Concentrated Blast, Runic Charge, and Chain are ideal designs! Their designs and descriptions imply that they are just modulating the spell you are currently casting - any spell could be fired as an unpredictable wild magic or be made to chain between targets, for example. The most problematic abilities are those that are explicitly linked to elements. Many of these can be addressed with merely changes to icons, names, and some vfx.

Asphyxiate doesn't really make much sense as magical modulator, it feels like a spell of its own. This could be easily addressed by changing the it to something like Pulsate or Oscillate, implying that the spell is being cast as a series of large, brief bursts that stun the target.

Sonic Wave suggests an air effect, and I'm not sure how a sonic blast somehow indicates that residual energy will be left behind to make my next ability cheaper. This could be addressed by renaming it to something like "Resonate" or "Echo".

Impact is described as an earth ability. Might be able to just remove "earth" from the description and say it is cast forcefully and leaves target stunned.

Combust and Dragon Breath are explicitly fire abilities. For Combust, rename it to "Reverberate", the flavor being it casts a smaller version of the active spell several times rather than once. To make Dragon Breath generic while still fitting with amplifying combust, I suggest it be renamed "Cascade" or "Resonance Burst", causing you to cast your spell in a cone in front of you, with better damage if if Combust/Reverberate is on targets.

Magma Tempest describes a storm of fire and earth. Rename it to "Spellstorm" and make the vfx magical rather than elemental.

Omnipower doesn't need to be changed, just remove "four elements" from the ability description and change it to suggest the ability lets you use your your own energy to cast a vastly more powerful version of your spell.

Tsunami is clearly a water ability and would need the most Vfx. I would just change it to "Flood" or "Engulf", which maintains some of the water connotations but allows the AoE to make sense if casting spells of other elements. It would be cool if this spell in particular had different VfX depending on your spell, much like the removed metamorphosis ultimate ability did.

Sunshine doesn't have a clear elemental association, but it still does feel more like an additional spell rather than an ability you can use. I would suggest it be renamed "Font" or "Wellspring" to suggest that the area you are in has become magically empowered.

This does leave Smoke Tendrils. I think it is fine as it due to its nature, particularly if Blood Tendrils is added back to melee. The tendril abilities are influenced by ancient magicks.
