First: What else is available at level 6? or should I swap my feats around?
Second: These Shadow spells don't seem to be nearly as uber as metamagicked out DD spells... Why are they good? (Also the extra will save, then a reflex save etc can get tedious in combat)
From the CrystalKeep:
Extraordinary Spell Aim:
With a Spellcraft check (DC 25 + spell level) you can shape an area spell so it does not affect one creature within its area. Casting a spell affected by this feat is a Full Round action, unless the spell’s casting time is greater, in which case the casting time in unchanged.
So this spell is good for through big AoE's and not killing one of your party members?
