Fresh Blood of the Corrupted item

Blood from torn flesh and bones of a Corrupted Delain. Once a Delain becomes corrupted, the Chaos Shard within their body begins raging. In no time, their consciousness is erased, and the Chaos Shard rips through their flesh and bones to come outside. Delains who gave in to the power of Demons and became corrupted have thirsted after living creatures, a thirst that can never be quenched. The once-rational creatures are ruled by a hideous instinct. Remember... that restraint and training is the only way to not fall for the seduction of sweet blood. Right-click to add to the Adventurer's Tome.
