Rain of Stones?

I dont know that you can really say that Fire storm affects all units though.. I think it hits like what? 10% of units per turn or something like that. Seeing as how it doesnt hit 100% I think it would be difficult to say that it is in fact actually hitting the normal percentage of troops. The advantage there is that it just keeps going and going until eventually it will definitly be hitting the normal amount of troops per turn.

But it could be that battlefield Enchantments do actually do what they say opposed to Battlefield wide spells. It just doesnt matter so much either way in that case since it continues to work its magic for the duration.
