I love carousing rules. Ashrezzar is a city of demons, it's my take on the Iron City of Dis. In this Hellish community there are plenty of shops, restaurants, and more for characters to blow their devil dollars on. Doing this can heal Despair damage, and lead to some other side quests.

The Dice Chain. This is something I shamelessly stole from Goodman Games because I'm a filthy sneak like that. The OSE Dice Chain is as follows: d3, d4, d6, d8, d10, d12, d20.
The DCC Dice Chain is as follows: d3, d4, d5, d6, d7, d8, d10, d12, d14, d16, d20, d24, d30.
I want referees to use whatever dice chain they wish. You can easily create your own dice chain. If you'd like to buy some d24s and d30s they sell them at Impact! Miniatures

I must warn you, players will lose their shit when they have to roll a d7!

Tattoos. I have a tattoo of a sword on my forearm, it's the sword of Achilles from Infinity. My wife's friend has a "Live Mas" Taco Bell tattoo on her butt cheek.
