Depends on trigger. If it's on-hit most definitely it only work when hitting enemy. But on-kill like reap and overkill should work regardless if the enemy dies from hit or a spell effect. I'll review overkill tho, in case I missed something.
hey i checked and it's a matter of the reap spell/trait not being in the same place as how other spells are triggered. So yeah its def broken in this version, but it should be fixed by next update. Thanks for letting me know
