@aimlessone this always multiplies incoming damage - in player case 0.0 to 1.0 * original damage and in NPCs case 1.0 to 11.0 * original damage. So if you set 20% in player column then player damage will be 1/5 of original damage. If you set +200% to NPCs damage then all damage to NPC will be multipied by 3 (1.0 + 2.0).
