Re: Shadepriest (3.5 Base Class, PEACH, somebody? anybody?)
They have 9th level spells off a nice list; just remember that; the recharge might be a bit much.
Empowered Essence Drain+Enervating Essence Drain+Withering Essence Drain: I am Incorporeal. I use Essence Drain, and then, upon successfully hitting, activate Enervating Essence Drain, thus inflicting 12 Constitution damage and a negative level.
Which is entirely appropriate, I would say.
