The implementation of darkness is extremely poor. It is not supposed to be an environmental cloud effect which can be replaced by other cloud and surfaces. Enemies also seem to be able to shoot into the darkness from high ground without issue. The whole spell needs to be reworked. The ai should be guessing where the player is inside and firing shots at locations rather than being unable to shoot on at all. It should not be coded as a cloud effect as the engine seems to be unable to have 2 clouds on the same zone. An acid flask should not displace a patch of magical darkness. Please fix this.
