Penetration is the act of bypassing the PV of a creature in combat, dealing additional damage, or in some cases, dealing damage at all. The PC does not normally penetrate the PV of monsters. Several possibilities exist to achieve this effect. Penetration is an effect seperate from critical hits. A hit that bypasses PV has no greater or lower chance to be a critical hit and vice versa. Against monsters with high PV scores, both will lead to significantly increased damage output; combined they are simply even more powerful.
