Feral Goblin

Feral Hunter - Once per combat, you may deal an extra d4+ your level, damage on a successful hit. If you are wielding a light simple weapon (such as a dagger) you may roll a d6 instead.
Hunter's Instinct - You are proficient with the survival skill to track down game.
Darkvision - You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.
Hidden from prey - You can take the Disengage action as a bonus action.
Small creature teamwork - During combat, if another small creature you are friendly with is within 5ft of an enemy you have attacked, you may use your reaction to grant that friendly creature advantage on their next attack, you must decide before they roll. That small creature can give you this effect as long as you pass the requirements from their perspective.

Languages. Goblin is the only language you know. The feral goblin dialect is filled with harsh short words that may sound like animal sounds. A feral goblin with 17 or higher intelligence may know common or gnomish.
