royal revenant (elden ring)
Royal Revenants are a minor boss and rare enemies in Elden Ring. These large undead creatures have multiple pairs of arms and legs, hidden by their ragged cloak, given them a human-centipede like appearance. Their attacks are fast, persistent, and they can disappear into the ground and reappear under you or spew deadly poison.
Using any AOE healing spell near them will not only deal massive damage, but also stun them for a riposte
