The Splash Element Effect, like all Elemental Augments, can be added to certain weapons to give them an extra watery effect. In order to enable the Splash Element, you must use the Water or Parasol Copy Abilities on one of eight weapons (Bomb, Cutter, Hammer, Ninja, Staff, Sword, Whip, Yo-Yo) that can be combined with the Element. For example: You can add the Water Copy Ability to the Hammer Weapon to create the Splash Hammer. (In order to perform an Elemental Augment, you will need Kirby along with another ally that has that given Copy Ability.)
