Dominance

Dominance is a passive skill in Diablo III. It is unlocked at level 50.

In-game
This skill is most useful against hordes of lesser foes. 10 stacks means that a total of 20% of Life shield can be maintained, with up to 7.5 seconds duration.

Enhancements:

 * Ashnagarr's Blood Bracer (Legendary Bracers): increases potency by 75-100%.

Development
In patch 2.0, Dominance replaced Critical Mass.

Originally, it absorbed flat amount instead of maximum Life percentage.
