Charged Creeper

Charged Creeper is a mob that spawns during the Thunder event from the Blood God Shrine on the Hub Island. It has 17500 HP and it is level 50. It drops 1-3 Enchanted Gunpowder per kill. They can spawn everywhere a hostile mob can, apart from private islands. Standing near a charged creeper causes it to blow up, dealing 300 damage and knocking back the player by about 1 block. The knockback and damage does not trigger if the player has an item that blocks hits such as the skeleton helmet.
