Stink-balls are thin skinned capsules that get filled with gross liquid known as stink-ball juice.
It is possible to brew your own.
Stink-ball Capsules (SBCs) can be purchased from your local Spyware & Rockets store.
Typical Stink-Ball ingredients include:
Brew for 1 month on a cast-iron pot over a fire made from the bark of a hammaphore tree.
Once brewed, let chill, and then fill the capsules. Be sure to seal capsules properly so they don’t leak in your backpack or holster.
