About this project
What does Item Quality System add?
This mod adds an Item Quality system similar to the MMORPG Haven and Hearth, minus the cringe character stat quality caps.
Quality can range from the base Q of 10 to an extremely rare "perfect" Q of 9999. This is distributed in a richness noise system that applies to dimensions separately as well.
Tool quality will softcap quality of blocks, so it's always good to come back and check high quality areas with better quality gear. Netherite tier and above completely bypass quality limitations when harvesting blocks, so a q10 nether pick could harvest q9000 blocks with no quality loss.
Gear/food/weapons/etc will be boosted up to 6 times normal values when Perfect Quality. These gains are distrubuted with diminishing returns from 10 - 9999.

Should be compatible with modpacks, as long as configs are setup appropriately.
Reach out to me if you encounter any issues! The goal here is to be as modpack friendly as possible.
