Grog said:What about Wish? It costs 5,000 XP to cast and they nerfed it basically into uselesness in 3E.
Except for the XP cost and some codified uses, wish is exactly what it's always been in (A)D&D: a way for a high-level wizard to break the rules. Since what comes out of the wish is entirely under the DM's control, it can be either the most powerful spell EVAR, or the most dangerous one. Possibly both, depending on how the DM is feeling on the night.
