Ender IO - The Ender/MK2

[Meovyle]

Hello,
Im trying to get The Ender or The Ender MK2 sword to be buffed with RF.
Ive tried both adding in an anvil/dark steel with a octadic capacitor but i couldnt do anything...
How do you make it?

I believe you add a vibrant crystal to it. That said, you should be able to check the uses in JEI to see what modifications you can add.
