All runes are legit.
Some gameplay tips:
The runeword is not cubed in the Cube. First, you need to the corresponding runes, and then put the runes in a certain order into gray equipment with the correct number of sockets (other colored magic equipment will not work, like magic, rare, unique items). White items can also be socketed, and they turn into gray socketed items. If you have followed all the instructions but still can not get it to work, probably it's a ladder only runeword and you are playing on non-ladder.
