Damge = Random Effect
Explanation
Every time you get damage you will get a random effect. Every effect that exists in java 1.21.4 is possible. The potion will start on level 2 and get higher each time the potion is rolled. The duration of the effect is random but the maximum is custimisable with /gamerule maxPotionLength. The default value is 120 seconds.
Wither and Poisen effect
I think that wither and poisen souldnt give effects since this would make the challange almost impossible. But I also thought there might some pros out there so I made it that the wither effect doesnt give any effects and poisen. But you can also turn Poisen on and off with the /gamerule givePoisenEffect. The default value is false.
Requirements
The mod is required both server and client side
