Soulbound Remnants

Overview
–
This mod let’s you keep some items on death. Includes armor, tiered items (tools, weapons) and rare items.

How it works
–
When you open a new world the keepInventory gamerule is set to true. If you die, instead of keeping the whole inventory, only armor, tools, rare items and configured items will be kept, everything else is copied, cleared from you inventory and spawned into the world at the location you died.
