Ruin Sentinels

The Ruin Sentinels are bosses in Dark Souls II

General Information
The Ruin Sentinels can be found in The Lost Bastille past a large group of Royal Swordsman. The boss fight is a three on one if you don't have any phantoms, however, if the player doesn't jump of the platform with the first Ruin Sentinel, the others will not aggro until its death.
