Description
TwoGraves
Keeps your items safe on death
On death you spawn a gravestone that will take and keep all your items till you return. A simple right-click will put all items back into the slots they came from (so no more annoying re-equipping, this mod does it all for you). The grave is explosion resistant and (optionally) indestructible. Works in single- and multi-player.
Why yet-another-grave-mod you ask? Because this one works, no bugs, no bu***it, it's lightning fast and (really!) compatible to many major mods out there. Also future-proof thanks to open-source and a permissive license, should there be a need for someone else to continue it.
