Death kits
A death kit sets the items that should drop when a player using that kit dies. This is useful when a scene needs a particular drop, even if the player has changed what they're carrying.
Fill your inventory with what should drop, then Set Death Kit in the kit's All Settings dialog. Or:
commands
/kit setdeathkit <kitname> [skip]Run it with an empty inventory to clear the saved death drop. skip leaves the existing death-kit setting alone; it doesn't clear it.
Test this with the death and keep-inventory settings you plan to use for the scene.
If a scene needs someone to drop a specific item on camera, you don't have to hope they were holding it.
