I can't remember too well how this cheat works, but as you know Moria is a very tough place so you need health potions.
When I accidentally dropped a health potion with lots of pipeweed I quickly picked the health potion, but there was another, so I picked it up so this way I made a health potion spawning node it works with other items too (I made lots of good swords!)
It's very useful if you need 2 items, but have only 1 and can't find the other (BTW I did it on a switch maybe that has something to do with it?).
