The Sentinel uses both biotic abilities and Tech attacks. It excels at taking out armour and shields, and at staying alive.
- Throw – a projectile that pushes enemies backwards
- Warp – an attack that detonates biotic effects and damages armour
- Lift Grenade – a grenade that lifts enemies
- Tech Armor – reduces damage taken but slows power usage. Can be detonated to deal damage.
- Overload – destroys shields and deals damage. More effective on synthetics.
- Cryo Blast – snap freezes weaker enemies.
