Type : elemental
dungeon : violet hold

bug : abis shield hilank nda spawn anak2 nya
fix : Comes out with a shield that lowers all damage taken by 99% with a set number of charges. Each hit takes it down one and when it reaches zero he explodes, knocking everyone back for a little damage and spawning adds.
