Okay, I am making a Necromancer hero and I am making a spell that shoots out a tower-like structure (using tinker base ability) and then I want that tower to have Dark Arrow. Unfortunately, I don't think if I gave it Dark ARrow it would automatically be autocast each time it spawns via previous spell. Is there anyway to make it automatically be autocast? Also, if that is too complicated/impossible, is it possible to make a passive spell with a Dark Arrow-like effect? Thanks!
