Upgrade Crystals

by thetrueshockwave

Upgrade Crystals adds nine gems to Minecraft, each of which grants a permanent statistic boost once it is used on a player.

NeoForgeClient and serverAll rights reserved1.21.1

What it does

Each crystal raises a single stat: Heart Ruby grants an extra heart, Tempo Amber speeds up attacks, Fury Topaz adds attack damage, Stalwart Emerald adds armor, Aegis Amethyst adds armor toughness, Fortunate Morganite raises luck, Swiftness Diamond raises movement speed, Mystic Aquamarine speeds mana regeneration and Arcane Sapphire raises maximum mana. The mod is configurable, so server owners can change how often gems drop and which sources produce them.

Gems come from mobs, from chests and from mined stone, and the drop sources can be changed in the config file. Craftable Void Stones and Transmutation Crystals let a player recover a crystal that was already used and switch it for another. Installation covers the server and each player's game. Optional support exists for Ars Nouveau, AttributeFix and Iron's Spells 'n Spellbooks, and AttributeFix is recommended for the stat changes. Files are published for NeoForge only, for 1.21.1, with 2.0.0 as the latest file. The code is closed: the license is All rights reserved.
