A datapack for Minecraft 1.19. This datapack is similar to the Infuse SMP, although there are a few changes.
Features of the datapack:

-When you die, you either gain a negative effect or lose a positive effect if you have one.
-When you kill somebody, you either gain a positive effect or lose a negative effect if you have one.
-Custom item that when used gives you an extra effect.
-Custom item that revives a random online dead player, putting them on the almost all negative effects. (If no banned players are online it will not work).
-If you die with all the negative effects you get put into spectator.
-'/trigger effectwithdraw' to give you a potion bottle from your effects that when used gives you an effect.
-'/scoreboard players set {PlayerName} effect {NumberOfEffects}' to set player effects (admin only) 0 is no effects, and all others should be self explanatory.

I started making this datapack ages ago but I couldn't fix two bugs so I gave up for a bit. I started working on it later but had to resort to making the effects not randomized. I may add a configuration that you can enable or disable whether natural deaths remove effects if enough people ask for it.

If you have found any bugs or issues, please comment them.

I have not tested any other Minecraft versions and so they may or may not work with this datapack.

You may use this for anything you may need as long as you don't claim it as your own work (i check PMC and Modrinth every week for infuse datapacks)
