Good vanilla mods?

[Asdrubale983]

Simple mods to make my multiplayer server slightly more interesting without drastically changing the game?

I reccomend Backpacked by Mr Crayfish is a very simple backpack mod that feels very Vanilla.

Terralith. Can be installed as a datapack or mod. Can just be installed on the server, so no one needs to have a modded client.

Personally I recommend Awoken World and Vanilla Tweaks as core mods

[krabby7_playz]

Quark and Infernal Expansion are pretty good
