Can a unit with Weaponmaster equip multiple gears at reduced cost (e.g., 2-3 equipments that cost 1 power for free)?

Ruling: No. Weaponmaster allows you to choose one equipment and use its equip ability with a cost reduction of 1 power. A single instance of Weaponmaster does not allow you to choose multiple equipment.

Nuances:

• If a unit had multiple instances of the Weaponmaster keyword, each instance would trigger separately and you could choose one equipment for each trigger.
