About this project
What does Ancient Curses add?

Discover altars older than times long forgotten and suffer ancient curses for lucrative rewards. Acquire gems and socket them into your new amulet and gear to fight back against the curses!
Cursed Altar: These altars spawn in the wild; right-click them to receive their curse, but beware that some curses are much deadlier. Completing a curse's rite will spawn a portal back to the altar, allowing you to reap rewards from a configurable loot table. Each altar also gives one gem of Broken, Polished, or Perfect quality, with a rare chance of tougher altars giving you an Ancient Gem with game-changing and quality-of-life effects.
If you complete a Cursed Altar's rite...
Interact with the altar, and its cursed energy manifests into loot, everyone's favorite. The altar then becomes dormant, and you may use its mysterious energies to fuse lesser gems into more powerful ones, place 3 like gems into the altar, interact with it, and watch as the altar fuses them. 3 broken gems become a polished gem, and 3 polished gems become a perfect gem.
Ancient gems can only be obtained by completing the highest tier of trial from a cursed altar.
Lapidary Table: A Lapidary table is one used by jewelers. This workbench will let you modify the existing gems inside your armor and amulet.
Golden Amulet: Crafted with 3 string, two gold nuggets, and a golden ingot, this item can be used in the Lapidary table to slot gems into for boosts to health, attack, armor/armor toughness, luck, and magic amplification
Embedding Gems in Armor: Embedding a diamond onto your armor in an anvil will add a socket to your armor. These sockets can house gems in a Lapidary Table and function similarly to an Amulet, sans the special effects of Major Gems.
Magical Amplification: This new stat makes beneficial potion effects last longer and sometimes makes them more potent!
