Ruin Sentinel is an Enemy Group of Automatons in the Inazuma region. They are usually found in groups, all Ruin Sentinels will take the form of a robotic cube when dormant. When not dormant, they will be patrolling on a fixed route.
Ruin Sentinels are also present when fighting the Perpetual Mechanical Array, with the boss itself being comprised of each of the four types.
All Ruin Sentinels (excluding the boss) contain a 'core', which can temporary disable them (much like the Ruin Guard, and other Humanoid Ruin Machines). However, these cores are only exposed during specific attacks (see Enemy Pages for more information), and some can only be disabled by the use of Catalyst or Bow characters, however there are some exceptions (i.e. Keqing's Stellar Restoration, or Xingqiu's Sword Rain generated from Guhua Sword: Raincutter).
Similar to Humanoid Ruin Machines, Ruin Sentinels cannot be staggered by stacking poise damage, making them very sturdy and prone to attacks which would usually knock back opponents prone to interruption.
Ruin Sentinels can carry a Physical RES of 30% (Ruin Cruiser and Ruin Destroyer) or 50% (Ruin Defender and Ruin Scout) making it less viable to use Physical DMG against them.
Perpetual Mechanical Array
- Perpetual Mechanical Array — an enemy that can split into four different Ruin Sentinels, in addition to assembling as one large machine.
- The Ruin Scout resembles the Psy Meduzoa from Honkai Impact 3rd.
- Their designs are based on biological aspects of nature, with each representing a different type of organism. This is untrue for the Ruin Guard, Ruin Hunter and the Ruin Grader.
- According to Muzhen during the Thunder Sojourn event, similar machines have once been dug up at The Chasm.
