The Sentry is a hostile block-shaped guardian that slides across surfaces to hunt down intruders.
Behavior
The Sentry is a cube-like guardian that clings to blocks and travels along the block grid. It seeks out the nearest player and traverses walls, floors, and ceilings to close the distance, striking for 2 damage when it reaches its target.
It is heavily armored: It takes greatly increased damage when hit by a projectile through that exposed face, making ranged attacks aimed at its open eye the effective way to kill it.
Spawning
They are placed as guardians within Ancient Shrine sites in the Aether.
