Armor Mimic

Armor Meld

When the suit of armor is reduced below half its hit points, it can split into 2–4 independent armor pieces (DM’s choice), each with half the current HP of the original.
Each piece acts independently on initiative, can make attacks, and has AC 18.
Pieces can merge back together as an action to regain the original form.

Magnetic Grip

The mimic can manipulate metal objects within 10 ft..
As a bonus action, it pulls one metal weapon or armor toward itself.
The creature holding the object must succeed on a DC 18 Strength saving throw or be restrained until the end of the mimic’s next turn.

False Appearance

While motionless, the armor appears to be a normal suit of plate or ceremonial armor.
Detecting the mimic requires a DC 20 Intelligence (Investigation) check.
