• What happened to the other features? If a feature is not listed here, it's still in the "do I want to keep it or not" limbo
  • Graves: there are a sh*t ton of mods that do graves, corpses and more, so there's really no need. Plus the death penalties have been changed so it's really no longer needed.
  • Player Stats: No damage when spamming has been moved into Misc Combat. Player attributes instead have been moved to InsaneLib as they can work server-side only.
  • Experience module: moved to Insane's Experience Overhaul. Not sure about the future of that mod if I find some other mod that satisfies me in terms of Enchanting overhaul.
  • Flint expansion: flint tools weren't used anymore so have been discarded and gravel isn't that hard to find so ground flint has also been discarded
  • Gold: not really needed anymore. The good thing about gold equipment is the high enchantability. No need for fortune. Still need to change the mining level via data packs.
  • Solarium, Durium, etc.: Already disabled in 1.20.1, these only added further clunckyness to the system. I think something like Caverns and Chasms with Silver, Necormium and the other is enough. Will not be supported by the mod tho.

  • Stats Buffs: Merged the MPR data pack to Enhanced AI

  • No Pillaring: not liked and unused
  • Sleeping and sleeping effects: unused
  • Sextant: not needed anymore as was made for biome based ores
  • Explosion Overhaul: moved to standalone mod
  • Fast leaf decay: many mods already do it, probably better
  • Seasons: as much as I like seasons, I'm trying to keep the mod as vanilla and as other mods dependency free as possible
  • Timber trees: HC's TreeChop is good enough with a few config changes
  • Foggy Weather: foggy weather was quite neat, but not a fan of it anymore
  • Third-person death: was buggy and not that cool
