Actually its a package that goes way back and edition friendly.
Last night we were playing 5E and plotting to capture a mage who killed one of our party members and had been doing evil things in general. Our current party is actually made up of moral and good guys. It's been a while since I think we have had a good group. We tend to play morally ambiguous characters. No pressure to be proper.
Rewind, we were sitting at the tavern discussing a plan to capture the mage. The night before I decided to buy a couple of things, a couple would be a Criminal background specialty. My guy, Sidwin the Sharp says "Don't judge me guys, but..." he pulls out a hood with a leather strap to secure it around someone's neck. A leather gag strap that included a object that fit into the mouth to keep someone from talking/screaming/spitting and it was also equipped with a buckle to secure it to someone's head. One size fits all. And lastly a good pair of shackles.
Total cost: 25gp
