Teleporting crystal

Sometimes, always travelling the same path to get somewhere you want is really boring and time consuming. So It thought a "teleporting crystal" would create remedy! It looks similar to the end crystal. To craft the teleporting crystal, you need purple crystal shards and an ender eye. You can find these crystal shards in the end. The crystal gets placed on the ground and another one anywhere you like. The crystals need to have the same name to be connected (give it a name with the anvil). To activate the teleporting process, the crystal consumes one ender pearl. The crystal will create a 5x5 sparkling effect around it for 10 seconds. You need to stand in this effect for some seconds to get teleported to the other crystal! But if you are unlucky, you will get sick and get the nausea effect for some seconds!
