I can't bring back the dead, and it doesn't work on someone who's so injured they can't fight. I can sort of get someone back on their feet, but they'll still be pretty hurt. It also won't cure any poison or other...effects on someone, and it only heals one person at a time.

I know people who can cure a whole group of people of everything and restore their health all at once with their persona. I'm just not the sort of person who's that much of a healer.
