Annoying Effects
by ACMnky2022
Annoying Effects adds 35 status effects that make surviving and exploring the world harder, for Fabric on 1.21.1.
What it does
The mod adds 35 new status effects that make surviving and exploring harder. Most of them only affect players, and each effect has a matching potion. Those potions are not available from crafting yet, so they are obtained with a command, and the author notes that more potions will come in later releases. A few of the effects only work on the client side.
Installation needs Fabric on 1.21.1 and works on client and server. The effect and potion items are listed with their identifiers in the project repository, which is open source under the MIT License. Players who want to try the effects can use the give command with the tangling nightmare effect, which applies random annoying effects to the player constantly, with an infinite duration and a level of 0. The author suggests tangling dream as a lighter alternative for players who find the nightmare too strong.
