Healing afflictions?

[Frumious]

I couldn't find this with the forum's search function, or much about it in the manual, so here's a newbie's question...

What are all the ways of healing afflictions besides recuperation? Does the spell Healing Light do it? I remember reading that there's a pretender that can, to, but I don't recall which one...

Without a good method, I don't see much good in using units with medium/high HP but low armor...
