On the Court Cases page under ways to obtain summons, the list under Pickpocketing suggests several targets. However, when you go to the Thieving Guide and look at the NPC's to Pickpocket, the court summons are NOT listed under the loot sections for any of the NPCs listed on the Court Cases page.

 

Also, under the "Monster Drops" section in the same area of the Court Cases page, "Giants" are listed as a source, but only the Bestiary page for Fire Giants list Court Summons as a possible drop. Ice, Moss and Hill Giants do not list them.

Thanks hotdog, I have edited the Thieving guide and have credited you. :thumbup:

 

Leaving the topic open for confirmation on other giants dropping these. There seems to be no confirmation about which giants drop them, different results from different sources.

Yeah, I wasn't sure whether "giants" was supposed to be "fire giants" or if it was referring to all giants, and their pages hadn't been edited.
