Is Aura

Aura-subtype enchantments that enter attached to a target creature and modify it with bonuses or abilities. Includes pump Auras like Rancor, scaling Auras like Ethereal Armor and All That Glitters, and totem-armor Auras like Bear Umbra and Hyena Umbra. Distinct from equipment.is_equipment, which detects the Equipment artifact subtype rather than Aura enchantments; distinct from equipment.equipment_payoff, which rewards having gear attached rather than being the attachment itself. Creatures that care about Auras without being Auras, such as bestow-payoff bodies, fall outside this scope.
