Skeletor Prime is a Mob that spawns in The Catacombs. It is a stronger variant of Skeletor. Skeletor Primes are summoned when three skeletons are defeated close together and merge. They also deal ✷ True Damage, making them an especially deadly mob even to more experienced Dungeons players.
A Skeletor Prime is spawned when three Skeleton Skulls are near each other and merge on The Catacombs - Floor VI or higher. Skeleton Skulls are spawned when Skeleton-type enemies are killed. In The Catacombs - Floor VI, there is a 50% chance for a Skeletor Prime to spawn when three Skeleton Skulls merge, instead of a Skeletor. In The Catacombs - Floor VII, there is a 100% chance for a Skeletor Prime to spawn.
When a player is nearby, a Skeletor Prime will run towards them and attempt to hit them, dealing damage. They will occasionally throw a Bone towards the player, dealing damage. Both attacks deal ✷ True Damage[Confirm].
Trivia[]
They can be killed like normal Skeletors, but keep in mind that they still can throw bones like Crypt Lurkers and normal Skeletors.
