Dominance increases the potency of certain defensive and healing abilities, and the duration of certain control effects (stuns, roots, levitations and encasements) from powers.
At high levels, Dominance must be higher than enemy Willpower to be effective.
The recommended Dominance for an Alert, Raid or Operation is needed to affect opponents in that content when using power based control effects.
Dominance is combined with Restoration to determine the potency of healing and shield abilities.
Healing = Base Healing Multiplier * (30% Restoration + 25% Dominance).
Shield = Base Shield Multiplier * (112.5% Restoration + 150% Dominance)
