*This is part of the "Arm" quests: Hands, Head, Legs. Start by talking to both of the Galka in the Upper Jeuno Weapon Shop. Make sure you're flagged for this af. You need only to speak to them once.
Get Garliage Coffer key off Fallen Mages etc... (pit where beetles are that you drop in to)
Once you have key, Coffer is in areas beyond Banishing Gates, will need 3 others to open it with you when you go to coffer hunt. Past the first basnishing gate, there are 2 other banishing gates #2 and #3. You may have to check both depending on which you choose, and where the coffer is located at the time. Once you open coffer, you automatically get coronet.
Check treasure/coffer map sites for exact locations. Make sure you have Garliage ingame map. You'll need sneak for bats, and sneak and invis for beetles and bombs.
if you don't have a lot of friends ingame like me, and if you want to get past that 3rd banishing gate, buy some stacks of oil and prism and head down to garlaige in the morning time (US). I went there today in the morning and 3 or 4 different pt's went in there and opened the gate (of course i went in there like a snake but i don't care) Now, i'll just wait for them to log and check those 3 coffer spots past that 3rd gate. Hopefully i'll get lucky :D
