General Information
This is the game's "secret" boss. Remember that demon you prevented from being revived? Yeah well you failed, you fight him at full power on floor 9-1 of the labyrinth.
Strategy
He has many attacks, and most of them hit like a truck. Stack as much dmg +/- and demonic dmg +/- as you can. Immunity to petrification is HIGHLY recommended due to his triple gaze attack that comes from random locations on the screen. Even if you are good at evading it, having immunity on will let you focus on dps. He has attacks of all elements ready to go. His ice attack hits hard, his lightning attack stuns, and his fire attack is massive. Despite it sounding scary, its nothing you havent delt with before. Stay alive, revive if nessisary. A large bank can win this one. NPCs die way too quickly, bring friends. His HP is massive, but he will eventually go down like any other boss, he has no way of healing.
