There are 5 different weapon classes in Lord of Arcana:
1H Swords are the basic weapon with high mobility and quick low damage strikes. You can equip shields and magic cards with it.
Maces are a chargeable, slow attacking weapon with powerful battle arts. Shields can't be equipped. Magic cards can only be equipped when the battle art Heavenly Fist is equipped.
2H Swords are a slower than 1H sword but with longer range and more powerful strikes. You can equip shields and magic cards with it.
Polearms have a long reach with specific hit range (just what the tip strikes) and have powerful kicking arts. Shields can't be equipped.
Firelances are the only long range weapon, along with possessing the ability to "charge up" by pressing the X button. They have two long-range battle arts and two short-range battle arts. Shields can't be equipped.
