Abandoned Iron Golem

Immutable Form. The golem is immune to any spell or effect that would alter its form.

Magic Weapons. The golem's weapon attacks are magical.

Wear. As the golem takes damage, it begins to fall apart. Every time the golem takes 20 damage, it takes a point of wear. One point of wear imposes the following effect: -1 AC, -5 ft. movement speed (minimum 10 feet), -2 STR (this also gives -1 on the sword attack & damage rolls), -2 CON (this also makes the golem lose 20 HP. HP lost in this way do not contribute to wear)

Sword. Melee Weapon Attack: +13-x to hit, reach 10 ft., one target. Hit: 23 (3d10 + 7-x) slashing damage.

Fire Blast (Recharge 6). Fire erupts from the golems mouth. Makes 3 ranged attacks (+5 to hit). On a hit, the target takes 2d6 fire damage. On a turn where this ability recharges, the golem is immediately stunned until the start of its next turn.
