DISCLAIMER: the commands used in the datapack are not made by me, but by BlockerLockerYT (click for YouTube video); I just put them into a datapack so that people can easily add them to their worlds in just a few clicks and enjoy this fun challenge.
Inventory Link is a datapack that does exactly what the name says - it links the inventories of all players on that respective world, so that they all share the exact same inventory at all times. This can make a very nice challenge or twist to an SMP - it can be helpful at times, since you need to do the grind only once for an item and everyone can benefit from it, but this blessing can also turn into a curse, since **if one player dies or removes an item from their inventory, it gets removed for EVERYONE. **
Take note that the datapack might be buggy sometimes, especially if multiple players keep trying to move the same item from one slot to the other - it might cause items to vanish or duplicate
Have fun with this chaotic challenge!
