Ultra rare0.7%ObjectiveOptionalMulti-player
Completed Swords of Sanghelios co-op with both Mantises on Heroic difficulty.
Co-op required. Swords of Sanghelios has two Mantis walkers - you and a partner each pilot one, both active at once, through that section on Heroic. Grab a Mantis each and roll through the battle together. Solo you can only ever crew one, which is why it needs co-op.
