The Sentinel

Sentinels are unique, bringing both tech and biotic abilities to the battlefield. They are versatile and always equipped to deal with any situation. After overloading an enemy shield, Sentinels have no trouble throwing the opponent with their biotic powers.
Sentinels are also equipped with the most advanced Tech Armor to keeping them safe in hostile situations. If overloaded, the system discharge and stun all enemies within a short distance.

Powers
Throw uses mass effect fields to hurl targets away, damaging them if they hit an object. It can also be curved around objects and cover to hit its target. Throw really shines when used in conjunction with Pull, which reduces a target's mass, and thus allows Throw to launch foes against walls or over nearby ledges more forcefully.

Warp spawns a mass effect field that damages enemy targets and stops health regeneration. Warp can be considered the bread and butter of the Sentinel's biotic offense, perfectly reflecting the class as a whole, lots of applications, but with limited power.

Tech Armor- This power generates an energy armor suit that boosts the user's shields.
A very useful multi-purpose ability, it's also the other defense-disabling ability available to the Sentinel. Overload focuses on shutting down enemy shields.
