Pact of Draconic Fury Feat 6Uncommon Arcane Archetype Source Dark Archives (Remastered) pg. 166Archetype PactbinderPrerequisites Pactbinder Dedication
You've sworn a pact with a dragon, giving you the ability to tap into the dragon's immeasurable power in exchange for adding to their hoard. You gain the Dragon Breath activity. In exchange, you promise to search for objects the dragon wants for their hoard upon request. These requests might be extremely specific unique objects, or they might be a broad category of objects. While the dragon agrees to pay you a fair price for the item you retrieve, the pact requires you to give your time and service.
Dragon Breath [two-actions] Frequency once per hour;
Effect You breathe deeply and exhale a line or cone of powerful breath, much like the dragon with which you made the pact. If the dragon had a cone-shaped breath, your breath is a 30-foot cone. If they had a line-shaped breath, your breath is a 60- foot line. If they had a burst-shaped breath, your breath is a 10-foot burst within 60 feet. No matter the shape, it deals 1d6 damage per level, of the same damage type as the dragon's breath, with a basic Reflex save, using the higher of your class DC or spell DC. This action has the same traits as the breath of the dragon you made the pact with.
