The Sentinel’s additional career skills are Discipline, Melee-Light, Perception, and Vigilance.
As the Sentinel’s shield protects them, so too do they guard their friends. Driven by a compassion for those who cannot protect themselves, or by loyalty to their comrades, the Sentinel is the bulwark against dangers greater than themselves. An immovable object to rally about, the Sentinel is happy to play the part of the anvil, letting their foes dash themselves against them while their allies get ready to hammer.
