OK so going along with the Sorcerer debate in the other thread I have a practical problem.
Our group just finished a campaign. I played a Human Celestial Sorcerer 7/Malconvoker 2 who focused on summons, and creative use of the Benign/Baleful Transposition spells. Stats were rolled Str 10 Con 12 Dex 12 Wis 16 Int 14 Cha 20
Enter the problem. I'm going to be bringing this character back as an 19th level...problem...he needs to be able to create demi-planes, and seal them from outside influence. He'll be building himself a dungeon, and a plane to trap his summons on. Really, he's become a lot more conniving, long ranged, and Wizard-like than any Sorcerer build should be.
The biggest challenge is my spell list - what do I take, and how do I mitigate the giant holes that are going to pop up by trying to do a job fit for Batman?
ps. Please don't let this degenerate into another Wizard vs. Sorcerer thread. I understand that I'm starting from a flawed premise, no need to rub it in.
