I said it before, but it doesn't hurt to repeat: Oracles are awesome.
It’s a perfect blend of mechanics and flavor. I can’t point exactly what is so cool about the class – maybe the way the curses work – but there’s something incredibly primordial about Oracles that I just love it (another reason could be that I deeply loathed D&D's Favored Soul as one of the most ‘flavorless’ class ever created – I know, an exaggerated impression).
New Oracle’s Curse
Graveborn: You are touched by Death. This could mean that you’re born dead (without breathing) or that you’re born from a dead woman. This could also mean that you literally died once and was raised from the dead. It doesn’t matter; when you came back you brought something with you (or you left something behind). You skin is cold and you have a deathly parlor. You don’t heal naturally, only through magic or long-term care. You also suffer a –4 penalty on Handle Animal and Ride checks with living animals and magical creatures. You gain a +4 competence bonus on saves against death effect. At 5th level, you only suffer half damage from negative energy attacks and reduce all energy drain by 1 (minimum 0). At 10th level, you’re immune to negative energy effects. At 15th level, you’re immune to negative drain.
