Hyrinity (Legacy)
by zChewie
Hyrinity, in its Legacy build, is a content mod for Forge and NeoForge that adds bosses, custom dimensions, weapons and a set of skill levels to Minecraft.
What it does
The mod layers progression onto the game. Custom themed dimensions carry their own strong blocks and several biomes, and each one slows or speeds up mining as the player moves through it. Minibosses and full boss fights sit along the way, and the lore runs through the new areas. Many new items, armor, tools, weapons and decorative blocks extend the vanilla set, and an open menu bound to a default key collects the mod's screens in one place.
Hyrinity also replaces parts of the combat math with its own damage and health system, including weapon and armor classes for melee, mage and ranger playstyles. Because that system can collide with other mods, the gamerule hyrCompatibilityMode can be set to true to turn it off, and the author notes that this clears some entity resistances that would otherwise conflict. Players who run the mod in a modpack are advised to add Enough Items for recipe lookup.
The mod is published for Forge and NeoForge, with files for 1.20.1 and 1.21.1. The newest Forge build is 1.0.11 for 1.20.1, and the newest NeoForge build is 1.1.1 for 1.21.1. Hyrinity runs on the client alone, and the code and assets are under All rights reserved, so it is not open source.

If you wish to use Hyrinity in a mod pack, if the damage and hp system collides with another mod you can simply disable hyrinity's system by doing /gamerule hyrCompatibilityMode true ### Note: you may have to clear off resistance from entities if compatibility wasn't already on before.
