The arbiter tribunal enabled arbiters to be warped through a stargate. Arbiters were surrounded by a permanent distortion field, making them extremely difficult to safely teleport through a stargate without a tribunal to act as a space-time anchor.[1]
The Arbiter teleports a group of friendly units in a 5 x 5 area to its location. Note that burrowed zerg units are immune to this ability, but siege tanks in siege mode can be recalled.
The Arbiter can prevent units in a targeted area (3 x 3) from moving, attacking, or using special abilities. Trapped units may not be attacked or affected by special abilities.
