Advanced Dungeons & Dragons 2nd Edition Wiki

When casting this spell and laying his hand upon a creature, the priest causes 1d8 points of wound or other injury damage to the creature's body to be healed. This healing cannot affect creatures without corporeal bodies, nor can it cure wounds of creatures not living or of extraplanar origin.

Cause Light Wounds

The reverse of the spell, cause light wounds, operates in the same manner, inflicting 1d8 points of damage. If a creature is avoiding this touch, an attack roll is needed to determine if the priest's hand strikes the opponent and causes such a wound.

Curing is permanent only insofar as the creature does not sustain further damage; caused wounds will heal—or can be cured—just as any normal injury.
