If you have the amulet of yendor, left click on an enemy (with rightclick-to-attack-mode) it will give you the option to use the amulet, together with the health potion and such. If you now go back to your full inventory and use the amulet of yendor there, it will be consumed like normal, but if you now go back to the monster tab, you can use it again, to achive a total of 100 exp boost. (Not sure if I explained this good enough)
