random effect
by unknown_56
Random effect gives a player a random status effect at set intervals, with a command to start and stop the challenge.
What it does
Once a challenge starts, the mod hands out random status effects, some helpful and some harmful, every few seconds. A command sets how many seconds pass between effects, so one effect can arrive every 60 seconds or at any other interval the server owner chooses. A second command starts the challenge and another stops it immediately.
The mod runs on NeoForge for Minecraft 1.21.4 and needs NeoForge alone. Only the server has to run it, while players may leave it out and still take part. Multiplayer is supported, so a group can take on the same challenge together. The code is not open source; the mod is released under All rights reserved.
