Most endgame content allows for a limited number of deaths before you can no longer access the area. Most areas allow unlimited leaving and re-entry for other reasons except while fighting a boss.

On death during a boss fight, the Map Owner may respawn all players into a new instance of the area to attempt the boss fight again.

The number of modifiers on a Waystone will reduce the number of Revivals available allowed when opening a Map. For pinnacle endgame content, increased Difficulty will reduce the number of Revivals available.
