So. I've decided to start stacking up some PLFs to make a good caster. Or rather, a super caster. I have a hard time understanding some of the mechanics, and was wondering if someone could help clarify.
So, Sorcerer past life feats says it gives "+1 to the spell DCs of evolcation"
Wizard PLF says "+2 to Spell penetration."
So whats the difference between "spell pen and spell DCs"
Also, when I hit a monster with say, Finger of death or some such spell and it pops up "Immune", is there any way to get a monster to not be immune to certain spells?
Spell power I pretty much understand, but any advice on how to get it as high as possible, or any suggestions for good gear to make it as high as it can get at level.
Any help on these issues would be greatly appreciated!
