From Dragon Mania Legends (DML) Wiki
Dominance can be learned by all Tyrant Dragons. It is an active defensive skill that applies two positive status effects, the first boosting the allied target's HP (acting like a shield), and the second taunting opponents causing attacks to be restricted to allies with an active Dominance buff. The effect of Dominance last 2 turns.
When Dominance is applied, an additional white meter surrounds the allied dragon's Health meter; when damage from any source is taken, it is first taken from the bonus Health added by the Dominance buff, until either the 2 turns are over or the HP boost is depleted.
Burnout (as usual) removes this buff before dealing any damage.
This skill can be used multiple times by one caster, but only the duration is prolonged. This skill is not stackable, therefore if two or more Dragons cast this same skill on a target, that target will have its defence raised to the strongest version.
