ooh, I’ve all but ignored this poor guy!
time to try to make up for that…
Cha probably needs to be higher than 12, maybe more like 16 or so.
I like your steal breath writeup. A few nits to pick, though:
Undead cannot have Constitution-based DCs.
I think the effect should be more deadly – say 3d4 Con per round. Why? “This requires one full round, at the end of which the victim must roll a successful saving vs. death magic with a -4 penalty. If he fails to save, he is instantly slain, but if he successfully makes his saving throw, he falls into a deathlike coma for 1d4 days.” Granted, D&D no longer uses insta-kill attacks, but we replace such things with very damaging attacks. And what about that coma on a successful save, if you make the save does that make you immune to further attacks from the steal breath?
