A Bravery Orb is an item added in the Origin Island DLC. When used in crafting as a God material, it automatically makes the craft become divine quality which is the highest possible quality in the game. If it's used as the only additional material, it will add a random special effect to the item. Refer to the Crafting Effects page to see all possible outcomes.
When consumed, it temporarily boosts all basic stats by 20 for the player and for nearby allies.
