Ruin Sentinels, Dark Souls Wiki

The Ruin Sentinels are an optional trio of bosses in Dark Souls II. They are also encountered later as respawning enemies in Drangleic Castle. The Ruin Sentinels can be found in The Lost Bastille past a large group of Royal Swordsmen. The boss fight is a three on one, and players must achieve victory through dividing and conquering, separating the individual Sentinels and defeating them one by one. The summon sign of Pilgrim Bellclaire, an NPC white phantom, can be found in a cell in the hallway
