Domination
Nothing delights a Dominator more than inflicting pain. Each time you attack, your sadistic nature grows. When your Domination is sufficient, you can activate this power to unleash your true potential.
Control powers do not generally exist in T3; those who do exist are costly and geared towards non-combat situations. Rather than add a host of such powers, controllers and dominators use regular powers, only exchanging damage for control.
Any Wound Point inflicted by a Dominator with a ranged Blast is halved, but any attack that inflicts damage also causes the loss of three shots. A target with no shots simply takes half damage.
Once per fight, in any sequence but the first, you can activate Domination as a 3-shot action. For the rest of the sequence, you will do full damage and cause a loss of shots.
Build
A dominator uses Powers skill and Super schticks. Dominators tend to be focused on direct damage and control using the special ability above.
