This weapon has a lustrous purple sheen.
When an implacable weapon deals damage to a living creature, the wound bleeds profusely and the creature takes 2 additional points of damage at the start of each of the wielder’s turns for the next 5 rounds. Multiple wounds are cumulative (a creature struck three times in the same round would take 6 points of damage per round for the next 5 rounds).
This bleeding can be stopped by a successful DC 15 Heal check or any effect that restores hit points (such as cure light wounds). However, while the wound is active, anyone attempting to cast a spell on the target that would restore hit points must succeed on a DC 15 caster level check.
An implacable weapon counts as adamantine for the purpose of overcoming the damage reduction of aberrations.
