Overview

Averzian uses Shadow's Advance to claim territory on the battlefield. Territory claimed cannot be retaken, and if Averzian claims three adjacent territories in a row he unleashes the March of the Endless. Causing an Umbral Collapse on a territory being taken prevents its capture.

  • Dark Upheaval inflicts periodic damage to all players.
  • Umbral Collapse inflicts damage to everyone that is reduced by the number of players at the impact location.
