Each character is able to equip up to three weapons and three items for use, and switch between them at any time. The player can get 3 extra slots for either by equipping the Backpack or Knapsack. Attacks are performed by tapping the attack button, or holding to charge a more powerful attack. Beyond regular equipment, a "Soul" item can also be equipped; it is charged by defeating enemies, and unleashed to inflict massive damage on nearby enemies. They come in various elemental types and levels of effectiveness. They are graded on the Roman numerals I, II, III, IV and V, with V being the strongest and taking the longest to charge up.
