Prison of Elders
The Prison of Elders is an Arena located in The Reef and features a randomized base mode with matchmaking available, as well as several higher-level challenge modes that rotate each week, offering more rewards. It applies a different Modifier each round, and a different set of Modifiers per week, and may contain critical objectives that the three-player team must complete, or else the team wipes.
In the April Update, this was expanded with the Challenge of the Elders with an Elder's Sigil required to gain access with scoring system implemented; points are deducted after five minutes have passed.
