I edited the original post. Some things have changed, some things haven't. Sorry to rez a dead thread, but I really want help on this. I have 88,000g to spend and two more feats to use. I looked at Life Drinker (DMG) and thought it was funny. I don't believe that fast healing or regeneration work with Warforged, which was what some of these posts were suggesting. I do, however, think that it will work NOW that I'm an Incarnate Construct and the Warforged Special Qualities were removed, and the Warforged Juggernaut Healing Immunity works differently. But I don't think it's very good, at least not if I can use the Craft skill to heal myself every round outside of combat.
Also, on page 270 of the Eberron Campaign Setting, what does it mean by "status effect" on the table of Docent Powers?
