Effect Gems Data Pack (1.21.8, 1.20.1) – Enhance Your Adventure

Description

Effect Gems Data Pack (1.21.8, 1.20.1) introduces a range of enchanted gems that can be equipped in your offhand slot, providing a variety of beneficial effects. Enjoy playing this data pack!

Features

Effect Gems is a simple data pack that adds new items called “Effect Gems” that can be put in the offhand 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!
