The Ender Porcupine is a block from Extra Utilities 2 that allows for wireless connections to other blocks, similar to Actually Additions' phantomfaces. For every block of distance between the Ender Porcupine and the block being remotely accessed, it consumes one Grid Power. It takes on the properties of the block being accessed, for example, if the porcupine is remotely accessing a chest, you may connect conduits to the porcupine like you can with the chest.
The Ender Porcupine transfers any actions done by machines to it to the block being remotely accessed. For example: if the Block Breaker is used on it, then it will break the block being remotely accessed rather than the porcupine.
