How to Raise Body Rank
Body Rank Increases by 1 per Survival

During a Hell Gate Exploration, your Body Rank increases by 1 each time you successfully evacuate using an Escape Pod. As your Body Rank rises, Exploration missions become more challenging, and surviving becomes progressively harder.
Body Rank Resets to 1 Upon Death

If you die during Exploration, your Body Rank is forcibly reset to 1, so avoiding death is crucial. Exercise extra caution when you have survived multiple runs consecutively.
Equipped Cores Are Permanent Until Death
When you survive and equip a Core, it cannot be changed, so choose carefully. Additionally, if you die, the equipped Core is lost along with your Body Rank reset.
Raise Rank to Equip High-Rarity Gear

The Body Rank required to equip an item depends on its Rarity. For example, 'Rare Rarity' equipment can only be equipped if your Body Rank is 2 or higher.
