Pack attack. Gobbers work together well. Any allies adjacent to the victim count as flanking, gaining the +1d6 bonus to attack. When 4 or more gobbers are adjacent to the victim, the victim becomes overwhelmed, and becomes Fatigued at the beginning of their turn.
Snatch. A Gobber can make an attack to snatch a weapon or item from an adjacent foe.
Death from on high. Gobbers can drop down on their opponent from at least 5' above him, making a claw attack. This knocks the opponent prone as well as doing the gobber's normal damage.
