Mutated Bloodvelds are stronger variants of Bloodvelds that require level 50 Slayer to kill. They are found exclusively within the Catacombs of Kourend.
Just like regular Bloodvelds, a Mutated Bloodveld's attacks are magic-based melee. They are known to damage frequently due to their high attack level, so equipping armour with high Magic defence is highly recommended here if you are not planning to safe spot or bring Prayer potions and wear high Prayer bonus gear while using the Protect from Melee prayer.
Mutated Bloodvelds are popular for players willing to spend time completing their task, as they provide better experience than normal bloodvelds. They also drop more blood runes at a higher rate compared to normal bloodvelds, in addition to the universal ancient shard and dark totem pieces most monsters drop in the Catacombs.
