Seraph Chest

The Seraph Chest is the locked bonus chest at the end of a Heist Battlegrounds run in Season of the Seraph. It costs 500 Seraph Key Codes to open, and it gives bonus gear on top of the normal rewards. It only becomes available after you finish the Heist Battlegrounds playlist activity. That playlist appears in the Helm once you complete the initial Season of the Seraph introduction.

Seraph Key Codes are a Rare material from Season of the Seraph. A player can hold up to 2,000 by default, or 4,000 after buying the Seraph Key Code Capacity upgrade from the Exo Frame. Ritual playlist activities are the most efficient source for them.
