Repair Mode
When the adamant sentinel is at 0 HP, it isn't destroyed. Instead, it enters repair mode, during which it's Slowed 1, can't take reactions, and can take only the Self-Repair action. Once it has more than 30 HP, it can use any type of action and can use reactions, though it remains slowed 1 and can't take any reactions until the start of its next turn. If a critical hit with a adamantine weapon reduces the sentinel to 0 HP, or if such a weapon hits it while it's already at 0 HP, the sentinel is destroyed.
Destructive Strike
On a critical hit, the adamant sentinel's fist Strike breaks the target's armor, if any, in addition to dealing damage to the target. If the target has a shield raised, the sentinel breaks the shield instead.
Inexorable March
The adamant sentinel Strides up to its Speed, pushing back each creature whose space it moves into and damaging them if they try to stop its movement. A creature can try to bar the way by attempting a save.

Success As critical success, but the resisting creature takes (3d10+17)[bludgeoning] damage.
Failure The resisting creature takes (3d10+17)[bludgeoning] damage, and its armor, if any, is broken. If the resisting creature has a shield raised, the sentinel breaks the shield instead.
