Digger. You have a burrowing speed of 20 feet.

Sniffer. Wolves and dogs have keen noses. You have advantage in Wisdom (Survival) checks using your nose.

Puppy Eyes. You may use an action to appeal to a creature's better side by looking forlorn and sad with big cute eyes. The targeted creature must be able to see your face clearly. They must succeed a Charisma saving throw or all attack rolls they make against you have disadvantage until the end of their next turn. The DC for this saving throw is equal to 8 + your proficiency bonus + your Charisma modifier. You must complete a short or long rest before using this trait again.

Anthropomorphic Speech. The experiments have given you the ability to communicate with your associated animal. You can cast speak with animals with this trait. Once you cast this spell, you can't cast it again with this trait until you finish a long rest. When you use this version of speak with animals, you can only communicate with the animal which you derive your traits from. So a kitzune would only be able to communicate with foxes, for example.

Trick Of The Trade
You have taken on a particular style of infiltration through training and observation. Choose one of the following options. You may choose a additional option at 7th and 13th level, but may not choose the same option more than once.
Hiding
You gain proficiency in the Stealth skill. If you already had proficiency in the skill, add double your proficiency bonus to checks you make with it.

Unarmored Defense
You posses a innate sense for danger that allows you to more swiftly dodge attacks when you aren't restricted by armor. When not wearing armor or using a shield your AC equals 8 + Proficiency Bonus + Dexterity Modifier.

Expertise
At 1st Level, choose two of your skill Proficiencies. Your Proficiency Bonus is doubled for any ability check you make that uses either of the chosen Proficiencies.
At 6th level, you can choose two more of your skill Proficiencies to gain this benefit.

Feature: On The Run
One way or the other, you escaped from the clutches of your captors. Whether it was a secret plan or you left guns blazing, your escape was not beneficial to your owners. Whenever you go around, be careful when sharing your past. You never know when someone might recognize a name, or even your face, and turn you in. You can be sure there's at least some sort of reward for bringing you back.

I am scarred and haunted by the memories of what I was forced to do.

Broken. This world is so new to me... sometimes I wish I had never left my captors. (Any)

My trust is not so easily earned by anyone.

I happen to get scared easily.
