The 'Auto-Battle' feature is excellent for grinding experience and SP on easier maps, especially in the Training Tower or early story chapters. You can set it to 'Auto-Battle' or 'Auto-Battle (Repeat)' for continuous farming. Stamina: Stamina is consumed for most battles. It regenerates over time, but you can also use 'Stamina Potions' to instantly refill it. Save your Stamina Potions for limited-time events like Tempest Trials+ or Forging Bonds, where efficient farming is crucial for maximizing rewards. Don't let your Stamina cap out; always try to use it before it reaches its maximum to avoid wasting potential regeneration.
