Dark effegy Bugs and Improvements

Dark effigy seems to not properly interact with a few chaos damage over time debuffs.

The first is decaying hex, this one is somewhat debatable but its damage is meant to be over a duration and even though its not specifically listed as DOT it still functions that way and therefore in my mind should function as a chaos Dot and therefore should work. It seems to just be an issue where the decay debuff is not propperly registering for dark effigy.

The second and more niche: Blackflame ignite. This one I understand more from a coding perspective, its complicated. But the same flag that allows ignite to be chaos damage could be potentially used to trigger dark effigy as well. I dont know enough specifics to really help, but I think It would be super cool to allow that synergy and maybe that would even help blackflame a bit since its a bit underpowered right now.
