[ He just said he had to clean it first!! But go off listing spells, Astarion. You are clearly not a healer! Xenk would find this funny if he had a sense of humor -- instead he takes him seriously, of course. ]

I am able to use my Cleansing Touch on the wound. However, if I do not remove the acid, the remains may fester.

[ He's immune to poison, not acid, so this actually doesn't happen very often to him... just his luck that these slugs would do that kind of damage. ]

I will be able to negate the damage once the wound is clean.
