Taia
SpoilerSorry for the gap in replying... looooong weekend.
Taia uses her eternal wand of lesser restoration (UMD take 10 [deceive item] = 37 vs. DC 20) to heal the ability damage -- (1d4)[4] CON healed (max 2), if 1, then use the second daily use to get back up to full CON. (Not that it'll appear to matter here.) Also, engages fiendish resilience to heal 1 HP/round for 20 rounds.
