DeathEffects is a fairly simple plugin that has a slightly more complicated function. With this plugin installed, every time you die, you will get a random permanent potion effect that will persist until you drink the special Effect Remover. You will keep the effects even if you die or drink normal milk.

The crafting recipe for the Effect Remover is configurable and the item is a milk bucket. By default, you can use it 3 times and this is the crafting recipe:


Commands:
/deatheffects getmilk [<player>] - Either gives you or the specified player the Effect Remover.
/deatheffects clear [<player>] - Either clears your or the specified player's effects, including persistent ones.

Permissions:
deatheffects.admin - Needed for the /deatheffects command.
