Renegade

Renegade is an NPC found in Shrines that resembles a large statue, offering the player a trade-off that provides one benefit in exchange for a cost.

Boss Fight
Renegade is also a Seal Boss that can be fought after defeating Overlord, but can only be defeated once per save file, without using the Mirror. The fight is initiated by finding a Shrine with the tradeoff "Unlock a Seal, Face Death." This tradeoff is randomly generated in the Maintenance System and Bellows, but is guaranteed in Sanctum shrines.
