Goblin

Goblins are small, toothy, warty folks found all over Ravnica. Circumstance and history have put them in positions to be most commonly found as researchers and attendants of the Izzet League, raiders of the Gruul Clans, pyromancers and technicians of the Cult of Rakdos, and soliders of the Boros Legion. A great many goblins are guildless and members of street gangs.

Always Looking Up

Goblins are small, wiry people with jagged ears and crooked, pointed teeth. Their skin ranges from greens to browns to dark reds.
Age. Goblins age fairly quickly, reaching maturity in their mid teens and living 60 to 70 years.
Size. Your size is small.
Speed. Your base walking speed is 25 feet.
Darkvision. You can see in dim light within 60 feet 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.
Nimble Escape. You can take the Disengage or Hide action as a bonus action on each of your turns.
Underestimated. Larger foes don't always look down. When you damage a creature with an attack or a spell and the creature's size is larger than yours, you can cause the attack or spell to deal extra damage to the creature. The extra damage equals your level. Once you use this trait, you can't use it again until you finish a short or long rest.
