There is no single best class. Berserker and Pirate are great for beginners due to their easy difficulty. Duelist and Enigma offer the highest skill ceiling. With 16 classes total, compare them by difficulty and playstyle before choosing your main.
How does the combo system work?
Combos chain multiple moves — attacks, kicks, parries, abilities, and dashes — before a timer runs out. Each combo level grants gold, potion essence, and invincibility.
