Releases all Rage Counters on the caster in order to deal damage to the
enemy. The more Rage Counters the caster has and the lower the casters
current HP, the greater the damage will be.[/quote]

Rage counters appear as 'spheres' floating around the royal guard. When Rage Burst was used,it deals damage according to the number of rage counters the royal guard have. However the rage counters didn't disappear after using rage burst,making rage burst always do the largest damage.
