Abilities and Skills describe actions that may be taken by playable characters. They may be unlocked by default or in the Skill Tree.
Abilities[]
In general terms within Disney Infinity, an Ability is a character's "power or capacity to do or act", regardless of their knowledge. This includes a number of Basic Abilities that are unlocked by default, as well as Special Abilities that, while not as common, are areas that further define the character.
Skills[]
In general terms within Disney Infinity, a Skill is a character's power or capacity "to do something well". For example, while any character may pick up the lightsaber toy and swing it about, only a Lightsaber Master can develop the skill to its full potential. Additionally, while many Abilities are unlocked by default, most Skills must be unlocked by spending Skill Points in a character's Skill Tree.
