This item spawns a loot split chest (and possibly mass identifier), with all functionality of a guild hall split chest, like !bulksource, !bulksell, etc. It can be used anywhere, especially on a freshly slain tag boss' corpse.
It is a convenience / QoL / laziness item, inspired by Portable Hole. It should alleviate the annoying running back and forth with asmo artifacts, or accidentally sending the banker to Encumbria.
I mean, if one person picks arties from Asmo's corpse, they can dump them into a chest practically next to it and split right away. As opposed to the marathon people are running in Sheinja or DT guild halls, no offense intended
