Challenge of the Elders

Challenge of the Elders is a Prison of Elders challenge mode added in Update 2.2.0. Entrance to the activity requires an Elders' Sigil, which can be purchased from Variks. Fireteam matchmaking is disabled.

Gameplay
Challenge of the Elders consists of three rounds of minibosses, two modifiers, and a certain action that will grant bonus points, all of which are rotated weekly.

New enemies will spawn five times depending on the boss's health.

Scoring
Every kill Guardians make contributes to the fireteam's overall score. Some actions, such as precision kills or melee kills, provide bonus points; the action that provides a bonus is rotated on a weekly basis. The following are the possible bonus point modifiers:


 * Precision Kill Bonus
 * Grenade Kill Bonus
 * Melee Kill Bonus
 * Super Kill Bonus

Five minutes after Variks announces the round (not to be confused with when the fight begins), Variks will get impatient and deduct 50 points from the fireteam's score. He will continue to deduct 50 points every 45 seconds until the boss is killed. To get the highest possible score, the fireteam needs to balance farming enemy kills for points and slaying the boss in a timely manner.

If all members of a fireteam are dead at the same time, the round will restart and their score will be reset to what it was at the beginning of the round.

Score Table
The following table illustrates the points earned for each action. There is a 2x multiplier during the second round and a 3x multiplier during the third round. The bonus modifier is also a 2x multiplier.
