If your FvS is non combat-based and you don't have max Wis, but you Do have max Cha, what is your stategy? Cast a lot of spells that everything will save against and have enough mana that you can cast it 30 times so that when they roll a 1 they die? I don't get it. When they save vs Destruction or Implosion, what's your back-up plan? Cast max empowered BB, believing with such a build you took caster feats, and hope that your 100/hit(cuz they saved!) will eventually make them give in and die?
I just see way too many FvS that don't have the stats to dps and have no wisdom to boot. But hey, they sure like that 34 Cha...
