[Arch-vile]

Double attackers, squads, etc. can only use Andask's Orb of Vengeance Aura once per turn. If a squad bonds, both the bonding hero and one squad figure can use the aura, because the hero is taking a separate turn.

Note that Kurrok + Elementals, Thralls, and Alastair MacDirk (w/Overextend Attack) can use the aura more than once since each figure takes a turn separately.
