Help Index :: Misc :: entropic regeneration Entropic regeneration slightly augments a reaver's regenerative abilities, both physical and spiritual. A reaver must be maintaining Ulthi's rite of destruction and one or more other blood rites to receive any benefit with additional rites granting longer affects. When an enemy is dispatched by the reaver's own hand, regeneration is granted based largely on the level of the slain creature. In order to maintain the enchantment, blood must be spilled on the battlefield.
