You missed the newer dupe methods, putting a bow in your inventory along with enough arrows to fill you up, having a quiver of arrows on your cursor when you die, and unless you drop the bow you wont get your body back, but you do get your items, and we all know you can't have a second body!

Edit: This is NOT a dupe method, it is a mere scam people have tried to pull on me

as Lord of the Undead I feel it is my duty to EAT YOUR BRAINS! or at the very least DRINK YOUR BLOOD!!!
