Hell quoins are hard to reach when you're energy is zero, which happens to everyone when they're dead. What you do is get yourself some Hell Wine and drink it.
Don't bother with the Qurazy Quoins though, they'll still be worthless, because your mood will still be zero.
Otherwise, enjoy the futility of it! It is hell, after all. You should be taunted for being there.
1. die.
2. have someone mourn your headstone. This is best arranged before you die.
3. once mourned, you will receive a ticket good for a bottle of wine. go get it.
4. drink the wine.
Sometimes, if you arrive in Hell before midnight, and wait a bit, sometimes -- sometimes! -- you'll be able to jump around after midnight, before the game realizes what's up and boots your happy ass back to the real world.
Also, in Cebarkul, there are generally lots of people around to celebrate/mourn your glitchy life! I try to every time I see a headstone without flowers.
