Colossus Dungeon

Ancient Colossus Dungeon

In the Colossus Dungeon lies a colossus, an ancient weapon of war. In order to face the colossus, you must dispatch a total of eight Astromons; however, you cannot dispatch duplicates of the same Astromon. During battle, players are able to switch out each party a limited number of times, with a short cooldown. If you are able to defeat the colossus, you will be rewarded with rare gems.

Each entry costs 25 energy, with up to 2 victories per day. Further entry after 2 victories cost (n+1)*100 astrogems, n being the number of victories after 2.
Clear this dungeon 8 times each week to receive a random Skill Book.
For every 20 clears of this dungeon, you receive Siegfried (Dark) soulstones.

All Colossus dungeon bosses possess the skills Invincibility (Immune to seal and action-inhibiting effects), Perfect Blessing (Dispels negative effects while increasing attack power and defense every 3 turns), and Greater Sap Resistance (Decreases the amount of damage taken from sap). They also possess a special "Doomsday" attack that they will perform once after falling below a certain amount of HP, with its own passive ability.
