Fun fact: Low level spells (0 and 1) are my favorite spells. Since any spellcaster can use them, they easily change the flavor of a world, and are usable from the very start. For the most part, these look like amazing additions.

A few nitpicks:

I'd recommend looking in Heroes of Battle for what they say about Trenches and Move Earth. They already have some stats for it, there.

Call the Lord seems a bit.. Well, I find it odd that it summons the actual form of the Deity. I see players using it more to manipulate people rather than for the morale bonus. Perhaps instead make it very clear that the illusion created is NOT the actual god, but instead represents the God's favoring of the casting side? Or something like that?

Cobblestone could probably be abused as a low-level way to turn dirt/sand into stone. I could totally imagine a King employing an army of 1st-level casters, having them Cobblestone piles of sand, then have commoners haul the stone away to make a giant wall. Or better yet, dump the sand where the wall is to be, then Cobblestone it. Kind of like casting Obsidian in Minecraft.

How does Master's Luck work when using Profession to work for pay, over a week-long period?
