Very tall and lithe, the Ruin Sentinel is armored from head to toe in what looks to be bronze. It has a narrow helmet slit, giving it a something of a robot-like appearance. These enemies are extremely fast for their size, and come at the player with a variety off attacks, many notable for their wide hit potential. There are three named Ruin Sentinels, Alessia, Ricce, and Yahim, who make up the the boss fight in the Lost Bastille: three Sentinels fought in a room: one on the platform near the entrance, and two below on the ground. See the Ruin Sentinel page for boss fight details and other encounters.
