There has been a few threads on this already, but I've been morphing land to my liking, when needed, when the price was 50 mana per cast. At 5 mana per cast, this is going to be pure abuse.
I could not agree more ! I love these two spells; but they shouldn't be too cheap !
Note to UmbralAngel: I have used "raise land" very effectively, to create a path to cross an inland body of water. I once had a map with a large inland lake. It was large in circumference, but fairly narrow at one point (4 tiles). I was on one side and an enemy AI that was weaker than I was on the other side. The edges of the lake were heavily forested, so getting around it was painfully slow! But by casting raise land, just 4 times, I created a terrific short cut across the lake. I could then much more easily attack, and capture, the enemy AI's city. It also gave me a short cut entry-point to the rest of AI's empire.
Which brings me back to GFireflyE's observation ... I really like these two spells, but I consider them very powerful; and I think they should remain fairly expensive. Otherwise, they will just will be woefully abused, and lose their Fun element ...
