Proto Bahamut is one of two Rank 80 raids. It is summoned from the northern Zinkenstill area, Azure Sky Sanctum. This raid is a primary source of Horn of Bahamut and Rusted Weapons, both used to craft Bahamut Weapons. You can summon Proto Bahamut at rank 80 and join at Rank 50. In order to summon Proto Bahamut, you must combine one True Anima of each element to create a Star Sand Scoop at the shop. You might also need to complete the Omega showdowns of Luminiera and Celeste to trigger its appearance.

Blue Chest Scaling

The Blue Chest drop rates for this raid are not calculated linearly like other Raids and follow a different plot.

• Damage dealt up to 10% of the raid's total HP, the Blue Chest drop rate is 1:1 with the % HP damage dealt. (e.g. 8% HP damage results in 8% chance of a Blue Chest)
• Damage dealt between 10% and 50% of the raid's total HP, the drop rate increases linearly at a slower pace, capping out at 25% drop rate for 50% total HP damage dealt.
  • This means that at least 120 million damage is required to match the Gold Brick drop chance from a Blue Chest drop in Grand Order (Impossible) or Akasha.
  • Any additional damage dealt past 120 million will result in higher Blue Chest chance, thus higher likelihood for a Gold Brick drop.
