Possum

Skilled at dramatics and playing dead, you gain the following benefits:

• You have an advantage on Charisma (Deception) and Charisma (Performance) checks when trying to pass yourself off as dead, incapacitated or more injured than you actually are.
• You can mimic the appearance and symptoms of up to two Conditions at a time. You must have seen the Condition you are feigning for at least 1 minute or have succeeded a saving throw that would have given you said Condition upon a failure. A successful Wisdom (Insight) check contested by your Charisma (Deception) check allows an observer to determine that the Condition or Conditions are faked.
