I have some suggestion for the Scar.
I feel like the Scars are a bit easy to get, especially since getting any amount of damage give you Old Wound token, and 1 in 6 chance of getting a Scar is pretty high, and at which point it sometime better to Break, than taking more Old Wound token. And it also discourage people from engaging in combat, and there especially in the early game, you only have 5 to 7 hit point, making Scar kind of redundence.
Here are some of my suggestion.
1. Lessing the cost for getting Reconstructive Surgery token, 300$ is too much for a thing that you will likely get often, maybe 100$, and also ditch the lower of the token or toughness thing, and just let you buy the token to get rid of the Scar.
2. Make the Scar heal naturally, I feel like this make Malice feel more dangerous since you can't just wait it out. How about Scar heal after 1d6 Investigation?
3. Increase the threshold of damage you need to take before getting Old Wound token. I feel like veteran character with 20+ hit point shouldn't get a Old Wound token from thing that deal 2 damage to him. Maybe if the damage taken is 10% of your total health, you gain a Old Wound token.
4. Increase the amount of Old Wound token needed to get a Scar, similiar to the last idea, but decrease the chance of you getting the Scar, with 1 to 5 hitpoint being 1d6, 6 to 10 being 1d8, 11 to 15 being 1d10, 16 to 20 being 1d12, 21 to 25 being 1d14, and so on and so forth.
