Performance mods
- Sodium: the single biggest FPS gain, especially in the queue and in crowded chunks.
- Lithium: server-side tick optimisations that also help locally.
- Entity culling and dynamic FPS style mods: useful when you're near big farms.
Building mods
- Litematica: required to build any schematic from this site. Shows a ghost hologram and a material list.
- MaLiLib: Litematica's dependency; install both or neither loads.
- A minimap with waypoints: for stash coordinates and travel routes.
PvP mods and texture packs
Crystal PvP players usually run a low-fire pack, a clearer crystal texture and a pack that makes totems and gapples instantly readable in the hotbar. These change visuals only, which is what keeps them allowed.
Short-sword or low-hand packs are popular for visibility, and a low-fire pack matters more than almost anything else when you're being crystal-comboed.
What is not allowed
Anything that plays for you: auto-clickers, auto-totem, kill aura, auto-crystal, reach or X-ray. These are the standard bans on any anarchy-style server and are what the anticheat actively looks for.
Rule sets change. Check the current DonutSMP rules before installing anything that automates an action.
