Burst
Each character has a Burst Skill, each associated with a type: I, II, or III. A squad should have all three of these types as each one is used in phases, in that order, after the III phase which the Full Burst is used.
Type I Burst Skills are generally characters of the Supporter class and Type II characters are the damage dealers. Having a shorter cooldown Burst Skill allows you to use the Full Burst more often.
