Good news, you no longer teleport around the Earth at random. Bad news you now teleport across the multiverse at random.
You are stuck in the universe you arrive in for one hour, you will not be teleported somewhere where you instantly die, such as a volcano or space, and when your hour is up you are returned to a random place from the place you left.
The place you arrive at can range from hugely beneficial, such as inside Scrouge Mcduck's vault, to rather benign, such as a random street in Kings Landing, or even very dangerous, such as Commoragh in Warhammer 40k. This means you have a 1/3 chance of being in immediate Danger.
After 100 jumps this power wears off. This drawback only activates once every 10 to 12 hours.
