About this project
What does Simple Effect Gems add?

Effect Gems is a simple mod 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! | ![]() |
