They are hit for double damage and the player has 2 hours to defeat them. This boss always begins with 10,000,000 hp.
The discoverer of a hidden boss is awarded 3 Ivory Keys if the boss is defeated. Additionally, the discoverer and anybody else who participates in the battle and does at least 1,000,000 damage to the boss is rewarded with 2 Ivory Keys.
