You can too make a Fort save when you're paralyzed; there's nothing at all preventing it (Reflex saves are a different matter).I use a Lich Sorcerer with the Necrotic spells, very nasty, they cant have the fortitude save when there paralysedso it can have uses especially for a DM but an imaginative player can easily use them. and for whether u know them or have to chsoe them for spells known, surely Dm's choice
So what are your on this feat and the spells that go with it? In terms of power, balance and overall snazziness?
