Crystal Mage

The Cursed Mage is a Hardmode enemy found in the Hallow biome during The Horde. It is a Caster who fires volleys of hallow magic at the player with a chance to inflict the Slow debuff before teleporting to a random nearby location. Once Plantera has been defeated, the Crystal Orbs it fires become Ghost Crystals, inflicting additional damage, with increased debuff chance and duration.
