Weapon Sets are sets of weapons and shields that provide special bonuses to players when the items of the same set are equipped simultaneously. They do not include armor pieces other than shields. Note that most of these sets consist only of a single two-handed weapon, so only one item is needed to receive the full bonus. The way to obtain them depends on the type of the set.
Vateshran Weapons drop in Vateshran Hollows, a solo arena in The Reach. Perfected versions of the weapons drop on Veteran mode. All weapons bear a resemblance to the Ancestral Reach weapons, but corrupted by void essence.
