Bosses
At the end of each land there will be a boss fight, where Thorald will fight the boss alone. Each boss fight has three phases, progressing to the next phase once the boss loses a third of its health.
Valgard
Phase 1: Valgard will begin the phase with a whirlwind attack. After the attack he will be exhausted for a few moments, leaving him defenseless. Afterwards he alternates between light and heavy attacks. More rarely he will use a lunge attack. If enough time passes he will repeat the whirlwind attack. All his attacks can be blocked.
Phase 2: Valgard will begin the phase with another whirlwind attack, unless he did it shortly before the previous phase ended. He will also have a new attack where he throws his axe at you. This attack cannot be blocked.
Phase 3: Valgard will replace the whirlwind attack with one where he retreats to one of the sides and throws three barrels at you.
