[Passive - On the Run] As you are on the run and don't want to be found, you are immune to all investigative actions. Every time you do get targeted by one, you lose a shot in your above ability.

[Active - Deathberries] You have possession of death berries ready to use at your wish. Visit someone and if they are Brokenstar or Clawface you will give this for them to eat and die. If they are not, you will not do anything for them. This counts a super-kill.
--Hidden Mechanic Activated: in the event that Spottedleaf dies, Yellowfang will become the new medicine cat.
[Active - Medicine Cat] You are the medicine cat of your clan which means you are the one responsible to take care of your clanmates. Each phase, you can target a player to protect them from kills. You can heal back lives.
