That being said, it might be a good idea to cut down on a few of the loas. I know that those are all of the loas from lore, but 6 seems like a bit too much, especially when a few are pretty bad(like Dambala and Shango). Either cut down on a few of them, or perhaps split them between talent tiers(but that would require a talent rework and his current talents are cool as is). If you decide to just cut down on a few of them, Dambala and Shango are pretty bad. the 4 remaining ones are much more evenly matched(Shango could be turned into a talent somewhere on his talent tree though, perhaps). The additional damage can't complete with the other effects, neither can simply adding a cloak to Q and a reveal to his other 2 abilities.
Otherwise, excellent work.
