If this runestone is active, a successful physical weapon attack (melee or ranged, but not spell) by the affected character against a monster will negate any ability–natural or magical–of the monster to regenerate or be healed. The no-healing effect lasts for the remainder of combat.
Note: Once affected by the Viper Runestone effect, the monster loses the ability to restore HP damage from any source, not just weapons with a Viper Runestone effect.
