Master of Malfunctions.
Foreman Gobblegrub has advantage on any check made to sabotage, jam, or jury-rig mechanical devices. Once per short rest, he can cause a non-magical mechanical item within 30 ft. to break or misfire (DM’s discretion on effect).

Goblin Cunning.
Gobblegrub can take the Disengage or Hide action as a bonus action on each of his turns.

Scrapplate Shield (Recharge 5–6).
Made from brewery tanks and broken carts, Gobblegrub's shield can block an incoming attack, adding +5 to AC until the start of his next turn. However, if an attack hits him while the shield is up, it breaks and becomes unusable until repaired.

Toxic Brewflinger (3/day).
Gobblegrub hurls a flask of volatile brewing waste at a point he can see within 60 ft. All creatures in a 10-foot radius must make a DC 13 Dexterity saving throw or take 3d6 acid damage and become poisoned for 1 minute. On a successful save, they take half damage and are not poisoned.

Actions

Keg Launcher (Recharge 4–6).

Ranged Weapon Attack: +5 to hit, one target.
Hit: 11 (2d8 + 2) bludgeoning damage, and the target must succeed on a DC 12 Strength saving throw or be knocked prone.
