Master of Earth and Stone: At-will Wall of Stone is going to build castles. Like, lots of them. Is that OK with you?

One with Earth: 30' tremorsense and a burrowing speed is a bit much for a lesser invocation. Tremorsense is a bit worse than the blindsense you can get already, but a burrow speed is very good. Not sure if it's worth a greater one, though. =/

Storm Blast: Just a fluff thing - why does Storm Blast paralyze someone? Do storms do that?

Work the water: does the water still flow to fill whatever container (or not) it is placed in, or does the cubic foot of water remain a cube even if you just place it on the kitchen table?

Good stuff, overall.
