Super fun mod, not balanced AT ALL!
Reputation ranks
Ranks only ever go up; points can drop but your rank stays.
About reputation ranksI have loved playing with inventory pets. Some are extremely powerful, with cheap or plentiful or farmable food (so it can perform it's ability forever), while some are quite costly and not very powerful.
I'd say the inventory management part is a bit outdated. The fact that you can't "load" food into an inventory pet instead of just keeping it in a precious and finite inventory slot is meh.
Other than that, very fun mod. Be careful with some of the newer inventory pets i've heard (and experienced) some crashed and issues.
I do have to say that if you haven't tried this mod in a survival world yet, I highly recommend. I know I'm harping about the cons, but it's genuinely a fun and engaging mod.
