D2 Nightfall: A Garden World

Nightfall Mercury: The Ordeal — Adept

Beginning with the reset on Oct. 29th 2019, this week's Nightfall takes place on Mercury. Specific mods are needed before jumping into the fray to defeat champions:

Overload Champions — These enemies cannot be stopped without an Overload mod.

Barrier Champions — These enemies cannot be stopped without a Barrier mod.

Vex Champions — This mode contains both Barrier and Overload champions, which will require Barrier or Overload mods, respectively, in order to defeat these enemies. Note too that exploding units (Martyrs) have more health.

Rewards — Achieving a score of 100k or more will earn a Pinnacle reward. Otherwise, completing the Nightfall earns a powerful (Tier 1) reward.
