LS Sphere

Leader Skill Spheres, or LS Spheres, are specific to Summoner Mode (often referred to as the 3rd Arc or Summoner Arc). These spheres can only be equipped by the Summoner unit, and only one can be equipped; however, they can stack with whichever sphere a friend unit is using.

Recipes for the LS Spheres are unlocked as the player advances through the stages of the Summoner Arc, and the spheres can be crafted from the LS Spheres icon on the Town map.
