About this Mod

Effect Gems Header

Effect Gems is a simple datapack that adds new items called “Effect Gems” that can be put in the offhand or mainhand slot to receive status effects.

	The gems can be obtained by killing a Gem Zombie. The Gem Zombie can spawn naturally throughout the world, anywhere a normal zombie can spawn. This means Gem Zombies can spawn from zombie spawners!
There are a total of 12 different gems that the Gem Zombie can drop. Each one will grant a different effect when placed in the offhand slot. There is also the possibility that the Gem Zombie drops a pearl, too!

Frequently Asked Questions

Effect Gems server crashes on startup – what to do?

Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Effect Gems officially supports datapack, fabric, forge, minecraft, neoforge, quilt for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Effect Gems – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Effect Gems consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
