Before the fight
- Rest at the nearest bell first. It refills your health and items and becomes your respawn point. See how saving works.
- Spend your upgrade materials before the fight. A reforge refunds them later, so you lose nothing by trying a different weapon. See how to upgrade weapons.
- Stuck? Drop the difficulty for one attempt and raise it again afterwards. You can change it at any time.
