About this project
What does Upgrade Crystals add?
A mod adding 9 new gems you can find for permanent upgrades.
The Heart Ruby, which grants an extra heart.
The Tempo Amber, which increases your attack speed.
The Fury Topaz, which increases your attack damage.
The Stalwart Emerald, which increases your Armor.
The Aegis Amethyst, which increases your Armor Toughness.
The Fortunate Morganite, which increases your Luck.
The Swiftness Diamond, which increases your Speed.
And, with Iron's Spells 'n Spellbooks-
The Mystic Aquamarine, which increases your mana regeneration rate.
The Arcane Sapphire, which increases your maximum mana.
Additionally, there are the craftable Void Stones and Transmutation Crystals, which allow you to get back your used crystals and even change them into others.
Each of the crystals is found by being mined!
I plan on adding Fabric support for current versions down the line, and soon 1.20.1 Forge with the latest rewrite. Sit tight for that.
