I have a few mods I can suggest, but need to know what version it’s on. (You do not need to add all of these, and I can say for sure that depending on the version, some will not be available.)
(In order of what I recommend more)
- Lag Reduction (***SUPER IMPORTANT***)
> Sodium, Optifine, Clumps
- Mistborn Specific
> Feruchemist Origins (https://www.curseforge.com/minecraft/mc-mods/feruchemist-origins), Flan’s Mod Western Pack (u can rename the weapons, and if you make a texture pack that changes stuff based on name, but you need Optifine, which is Forge)
- Map/Travel Mods
> Xaero’s Map, Xaero’s Minimap, Waystones (already mentioned but why not add it to the list)
- Effects
> Dehydration
- Communication
> Simple Voice Chat (if you watch Hermitcraft or the Life Series, this is what they use)
- Misc.
> Comforts (sleeping bags), Traveler’s Backpacks
- Camera
> Freecam, Better 3rd Person
- Inventory Mods:
> Inventory Sorting, Legendary Tooltips, Item Highlighter, JEI
-HUD Mods
> WTHIT/Jade (2 mods that do the same thing), Inventory HUD+
- Appearance
> Iris Shaders
- Biome/World Gen Mods:
> Terralith, Biomes o’ Plenty
- Additional Structure Mods
> Towns and Towers, Mo’ Structures, MVS
(I use a lot of these for my survival world, and like them a lot)
