The man casts lesser restoration on Korbach (DC 17 Spellcraft check will identify the spell as it is being cast) and heals (1d20+8)[25] Con damage that Korbach has taken.

The man is hinting that Milani is an underground deity worshipped in secret in Kintargo. It's possible that he is a priest of Milani himself, though Korbach did not get a good look at his holy symbol.
