How long can you leave items on the ground?

I was organizing my old ladder items with my non-ladder items this morning and I was cycling my characters through a game with my accounts (one character was always in the game). All of a sudden I noticed about 20 skiller charms I had on the ground just up and disappeared on me. I couldn’t have had them on the ground for more than 30 minutes. I didn’t think items disappeared that quickly (or at all).

Now you know not to drop items on ground unless they are picked up immediately.

After a very quick search, just to get you the duration.

i thought nothing dissappeared at all unless the game dies by having nobody in it for 5 minutes or so.

never actually tested this though

Nope. See the timers in the post above yours. I couldn’t imagine leaving skillers on the ground for 30 minutes, even if it was just worry over a DC. But either way you only have 20 minutes with magics
