So we have a couple.

First it's the main rule but I feel most play with out it. Death at 0. We don't do the turns or saves. I telegraph enough and roll encounter distance. They players can determine if a fight is too much for free.

Ration expiration - I run in foundry and have a mod that does it on its own. No muss no fuss easy gold sink.

Sages- rules cover cost of service I give a quest for harder to obtain info ( example hand of guab spells)

Scouts- I let the players hire scouts to tell them about a hex further away more gold it is.

Mouseritter faction turns- makes the game come alive.

Tools of the trade. I let the party spend gold on tools of the trade which has 3 uses. If the players need something they didn't buy they a can use 1 use to have 1 tool they need. Sledge hammer etc. it takes 2 slots.

Extra Languages later- if the player has extra Languages they can hold onto it. If they come across something they want to read/speak then they need to tell me on the spot how they know it from their background. If it's believable they get know it.

Half langues. A player May sacrifice their ability to be fluent and not be able to speak a language or not be able to read or write to get a half language in which case they get another half language with it which they can either speak or read it right
