Effect Gems
by Gamingbarn
Effect Gems adds gem items that give status effects to a player who holds them in the off-hand or main-hand slot.
What it does
Gems are added through a datapack, so the mod needs no mod loader for its content. Holding a gem in the off-hand or main-hand slot applies the status effect it carries to the player. The mod is a server-side install: players join without installing anything, and the server runs the effects.
Key features
Off-hand effects
A gem held in the off-hand slot applies its status effect to the player.
Main-hand effects
A gem held in the main-hand slot applies its status effect as well.
Datapack content
New gem items are defined in a datapack, so their effects can be changed without writing code.
