Pathfinder Chronicles: Kingmaker
Hard to Kill
All Wild Cards are considered to have the Hard to Kill Edge; they do not suffer Wound Penalties on rolls made to stabilise following incapacitation.
Buying and Selling Equipment
To reflect that merchants need to make a profit on goods they buy, and that equipment brought back from adventures is often in need of some sort of repair, all merchants buy goods at 25% their basic cost.
However, each merchant will usually have some task they require completing; for each task, quest or mission completed, the players can choose to either permanently increase the amount that individual will buy goods for by 25% (to a maximum of 75%) or permanently reduce the cost to purchase goods from that merchant by 5% (to a maximum of 10%)
