Sasa, the mysterious gem
by sasaeso
Sasa, the mysterious gem adds a rare purple gemstone found deep underground, which players use to craft a new tier of tools, weapons and armor for Forge on 1.15.2.
What it does
The Sasa Gem is a rare, vibrant mineral that turns up during deep exploration trips and rewards mining beyond the usual ores. Players hunt for it once standard survival tools are mastered, and it serves as the main ingredient for the strongest weapons and the highest-tier equipment the mod adds. The mod is meant to extend the late game and close the distance between standard play and endgame power.
Sasa, the mysterious gem is built with the Forge framework for Minecraft 1.15.2 and is published only for that version. The server and every player need the mod installed. The source code is available, and the project is released under the GNU Lesser General Public License v2.1 or later, which makes it open source.
