Multiattack. The wrecker makes two wrecking ball attacks.

Wrecking Ball. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 24 (4d8 + 6) bludgeoning damage. If the target is an object, structure, or construct, the attack deals maximum damage to it.

Clockwork Gnomes (Recharge 6). The wrecker fires tiny explosive clockwork gnomes at a point within 30 feet of it. Each target in a 10-foot-radius sphere of that point must make a DC 16 Dexterity saving throw or take 13 (3d8) fire damage and 13 (3d8) thunder damage. Nonmagical objects that aren't being worn or carried, structures, and constructs that fail their saving throw within the area take maximum damage.
