help > prayers > cure
This prayer can cure diseases, remove poisons, and alleviate blindness. The healer can pick one thing to cure, or he can cure all three maladies at once (for a higher sp cost and longer praying time).
Paladins devote more time to their fighting arts than to healing, and so can only cure disease. However, paladins don't need to specify disease as the target of their curative power.
