I took this edge hoping to be able to cleanse damnation but, it doesn't appear to work at all, regardless of the level of the damnation affect, and regardless of using cleanse versus remove curse. I'm hoping this is a bug as the helpfile is very clear!

Relevant help text:
> help remedy curses
REMEDY CURSES
REMEDY CURSES

Blessed by his or her deity, a healer with this edge is especially talented at
removing curses and damnations. This strength is reflected in both the healer's
'remove curse' and 'cleanse' prayer.
