Really, i think most if not all spells are fine except 1. Dispell. If you have to dispell my buffs and your a caster, then you need to reroll. Casters, i.e. clerics, FVS, Sorcs and Wizzies should rule the pit period. But than again, thats my rule of thumb, obviously others do not feel this way, or rather, take pride in their abilities to own me 3000 other ways.
But to each his own.
Stay thirsty my freinds.
