As it works right now, you cast meteor shower on your current location. This means the only way to hit mobs with it without dying is to pull them. The assassins mask makes it so you cant pull mobs without walking into cast range of most of the barracks and armory mobs. I dont know how to fix this but I think it is at least a choice between either letting us cast meteor storm on a target location or reworking assassins mask.

Change meteors to target nearest enemy?
