I'm playing my 1st character on ToME so most of my questions may be really dumb.
Anyway...
Because merchants buy your items at very cheap prices and resell them with a heavy price multiplier, I was planning to make a stash with some unused but cool items instead of saling them at a vile price. Thus, I dropped a pile of artifacts & other miscellania in some corner of the city of Derth, then I entered the Old Forest (and lost several lives there because this Wrathroot guy is definitely not a very friendly vegetable

Back to Derth, I found - without surprise, I admit - that the stash has been severely looted.
So... is there any safe way to make a stash somewhere if I want to save items for later without burdening my character ? Or can I only sell/re-buy items in shops ?
