Permadeath & Extra Lives

Permadeath — No Second Chances

If you die, you are warped out of the instance. There is no resurrection inside the instance. Once you're out, you're out. Come prepared or don't come at all.

Extra Lives

Milestone rewards also grant extra lives to each party member:

• Wave 75: Each member gains 1 extra life
• Wave 90: Each member gains 1 additional extra life (max 2)

When you die with an extra life, you revive at full HP after a 3-second cooldown. When you die with no extra lives remaining, you are permanently removed from the instance.
