Arbitrium+
The official client modpack for Taxphobia Vanilla Season 11.
Arbitrium+ is the recommended version for most players. On top of everything Arbitrium does for performance, it adds a curated set of quality-of-life mods that smooth out the rough edges of vanilla Minecraft inventory sorting, shulker previews, effect timers, and a few other small things that quickly become impossible to play without.
Nothing that changes how the game looks. Just things that make it feel less frustrating.
