Sentinels are unique, bringing both tech and biotic abilities to the battlefield. While they lack the focus of adepts and engineers, they are versatile and can handle any situation. Sentinels are equipped with the most advanced ablation armor system to keep themselves safe. If overloaded, the system will stun all enemies within a short distance. This advanced shield causes the sentinel to be like a "Juggernaut" so to speak, making taking cover much less necessary, and rushing your enemies much more productive.
