So, a player of mine is playing with an Earth Elementalist and he is using this ability every combat.

We are playing through Delian Tomb and the way I see it, its almost guaranteed damage (especially when he is using Persistent on it), it really wrecks the combat potential of some creatures (Goblin has Climb, Zombies do not) and it also will fall in a weird place where combat in the Mage Tower and perhaps in the delian tomb itself, it wont be "Mundane Terrain" and I shouldnt let he use it.

Is it really such an useful ability that is also negated by certain places? I just feel kinda bad about telling him that he cannot use it, and at the same time I feel bad for my bad guys that just keep falling and taking damage
