The Crucible is a series of grueling challenges that pit Guardians against one another in open combat. Crucible combat is live-fire, with Ghosts standing by to save the dead.

Whether alone or with a Fireteam, Guardians enter the Crucible to hone vital survival skills, build their own reputations, and win the patronage of City factions. Most importantly, the Crucible allows Guardians to train against formidable adversaries without fear of disaster.
