Ratling

Ratlings often stand a full foot taller than their mouseling relatives, also having longer tails and more pointed ears. They are tougher, more resistant to poison, and far more stubborn than mouselings, but are also unquestionably resourceful. When needed, a ratling can escape just about any enclosure that isn’t constructed entirely from metal and stone, a fact which many jailers hold in contempt.

Gnaw. You can use your action to chew through and break a small nonmagical object that isn’t being worn or carried, like a rope, a wooden rod or handle, or a length of fabric. If you chew on a wooden wall or floor for 1 minute, you can gnaw a hole large enough for a Tiny creature. You can’t chew through materials that are harder than your teeth, such as metal, stone, or crystal.
Rat Resilience. You have advantage on saving throws against poison, and you have resistance against poison damage.
