Invocation of Chaos was a granted skill on the old Will of Bysmiel that gave pets that did a combination of physical/fire/chaos damage. You can see this here: https://www.grimtools.com/db/items/896
The item has since changed to support Summon Familiar in the Mythical Version - and rightfully so. Bysmiel is more about lightning, not chaos and fire.
So the suggestion is to make something along the lines of a “Will of Solael” that brings back the granted Invocation of Chaos skill. This could support fire/chaos pets with something like Pyromancer, Vindicator, Elementalist, or Conjurer. Personally, I’d like to see support for Elementalist. But it makes a lot of sense to make Occultist included because hellhound is fire/chaos – Pyromancer would be okay too. Most items now have 3 different classes represented on them nowadays anyways.
It also would be nice to have the summons be more reliable. 40 second cooldown with 25 second duration is too long. TD and Aldanar’s can bring this down, but I think it should be like 30 seconds at MOST - theres a limit to how many can be summoned anyways.
So basically, general idea for the amulet:
Chaos Resistance?
+1 to all Demolitionist
- to something Shaman
- to something Occultist
Pet bonuses:
generic damage/speed bonuses?
50% physical converted to fire/chaos (this enables full physical conversion consistently with fiendgaze tomb which converts physical to chaos, without potentally needing Voidwhisper Bands)
Grants Invocation of Chaos Skill, buffed variant of the level 58 from Will of Bysmiel, lasts 25 seconds, cooldown 25 seconds.
Off of this, obviously there are some other things that could be modified to better support – Dracarris hasn’t seen use in ages and I don’t think will see any use as long as the proc is on enemy death.
