You drop on all fours and you get to move an extra two 10 feet when your health drops below 5 or if you are affected by the spell, Fear.

With your large ears, you have advantage on perception checks when hearing.

From a young age, you had to learn how to fight using only your claws, and tail.

• Claws: Because of your claws, you have a climbing speed of 30 feet. In addition, your claws are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.
• Tail: Your tail can be used as a whip. If you hit with it, you deal slashing damage equal to 1d4 + your Dexterity modifier, instead of the bludgeoning damage normal for an unarmed strike.

You are immune to disease.

You move through the streets shrouded and unnoticed. You use your tail and gain the following benefits:

• You gain advantage on Dexterity checks that involve stealing or placing an object with your tail from other creatures' person.
• Other creatures have disadvantage on Intelligence (Investigation) or Wisdom (Perception) checks to notice an object you lifted or placed with your tail.
• If you spend at least 1 minute observing or interacting with another creature outside combat, you can learn if the creature has a purse, wallet, pouch, or other similar object that contains at least 1 gp worth of valuables.

During combat, you can spend one action to make a cheap shot using your tail to throw dirt, sand, or snow, blinding your opponent. Your opponent must be within 1 meter of you and you must be in a location where there is either dirt, sand, or snow. Your opponent must make a Dex saving throw to dodge the dirt, sand, or snow. Once used, you must take a long rest for this ability to reset. If successful you gain the following benefits:

• Your opponent is stunned and can not move or do an action for 1 turn.
• You gain advantage on your next attack roll.

You can call upon the rats of the city to aid you in combat. A squirming, roiling mass of squeaking rats draws closer, teeth flashing and claws scratching everything in its path. This takes one action to summon. The rats can only be summoned in a town or city you are currently in and once killed or banished you can not summon them again until you have had a long rest.
