Destiny 2 Raids is a game mode that requires a 6-player team. These cooperative events are challenging endeavors that require communication for the team to succeed. A Power Level of 300 is recommended for normal Raids (Prestige Raids raise the recommended Power Level to 330).
While a raid team is within a restricted zone of a raid, a unique failure mechanic, rather than the usual 30-second respawn timer on death, applies. If a player dies within a restricted zone, the rest of the team has a short amount of time to revive the player. If a revive does not occur within this time, everyone that is alive is killed instantly, forcing the whole team to restart the encounter that imposed the restricted zone.
