Yep as essiw mentioned you can receive them (occasionally) as a drop from most monsters - wiki claims anything that drops a single summoning charm. It should have been listed as [spirit gem], since there is a chance of spirit sapphire/emerald/ruby from these monsters, which I've fixed now...but unfortunately items that are part of a group like that do not have dropping monsters put in that table, nor do they show up in search for drops. I can confirm there are 293 monsters in our database that drop them though. I'll ask Stev and see if anything can be done on that front, but we'll see. You are indeed right, there is no mention of the deposit box after completing the Hard Tasks, and brown aprons are out of style :P. We'll get that page fixed up shortly - thanks again for the help!
