Are you sick of dying and losing all of your items? Is keep inventory just too much of a cheat for you? Well never fear, keeper of inventories is here. As long as you have at least one in any slot of your inventory, you will not lose your items on death.
Keeper of Inventories in action

Want to know the best part? As far as I'm aware they work with the gravestone mods by default. I haven't tested it on all of them but I tested it on this one if I remember right https://www.curseforge.com/minecraft/mc-mods/gravestone-mod and if you die with a keeper of inventories you won't spawn a gravestone unless you don't have one.

The crafting recipe is just like a normal clock but with the other four slots filled with redstone as well.

I made this mod because I couldn't find anything like it... and then after I made it I found two mods just like it but they weren't for 1.20 so I decided to upload it anyway.

I might backport this to other versions and maybe I'll make a forge/fabric version but only if people request it enough, let me know which versions. For now I'm using NeoForge.

Also I don't check CurseForge very often so if you have an issue with the mod or want to suggest things or request a version backport join my discord server here https://discord.gg/P5G8shZvMu
