Can you help me find ALL THE METHODS one can try to keep quest items?

I know it's a weird question, but i'm starting an account where i try to bank or collect as many quest items as possible.

I already failed twice because i later on discovered different means to try out, so ths time i'd like to have a COMPLETE list of anything i can try to keep them in my banks, to not have any regrets once i've tried everything on the list.

Here's my current list, feel free to review it and add to it:


0) ALWAYS DROP AN ITEM BEFORE ANY DIALOGUE/QUEST INTERACTION (unless necessary), then pick it up again

1) Drop Trick
Classic and evergreen for old quests, not so much for new ones

2) Full Inventory
Works more often than not

3) Telekinetic Grab
Usually bypasses the "you can't keep two copies" error

4) Server hop

5) Table Placement
Rarely works, but when it does, you feel like a genius

6) Bank, then try to take another copy of the item

7) IMP BOX
Almost never works, but ESSENTIAL when items get deleted when leaving an area or when teleporting to bank with it is impossible.

8) Death drop (check skull first as well)
Couple of times it worked, but for things like the Fox/chicken/bridge puzzle it didn't, so hit or miss.

9) Juggle drop
Drop an item, transport the copy up to a certain distance, go back to recover the item, transport such item further than the last one, go back. Rine and repeat till you get to the quest npc.

10 LAST RESORT) Deliver the item, thrn go back where you originally found it and see if you can still get it

Thanks in advance for any additions, and please, LET ME KNOW IF I GOT THEM ALL.

 

sounds like an odd achievement to try to accomplish
