My tactics. 1. Full health and mana and witch cure potion. 2. Activate skills for max HP + MP and skills for magic power, speed and luck (preferably pumped to the maximum). 3. Combine magic strikes and health regeneration from the potion. 4. Use the celestial mode several times, but do not waste the celestial's blows on the enemy when he starts to recover. 5. The enemy has a strip of energy. He will restore his health until it is empty. 6. In general, you need to combine punches and celestial mode to deplete his energy supply. when it is exhausted, he will not be able to recover.
