This rather rare Artifact has one use only. As it says on the front, 'Go straight to Hell'.
Keep in mind that your average Netherworld Demon is not the brightest of creatures, so this card can be used to come and go from the Netherworld, with a little swift talking and slight of hand.
If you find yourself skewered on the battlefield, with your life passing before your eyes and no sign of resurrection from your God of choice, then pray that you have one of the cards tucked up your sleeve.
Use sparingly and wisely.
We have heard of resourceful Heroes who have used these cards to rescue fallen warriors whose Gods has failed them through shameful neglect.
