Am I Canni dancing wrong?

All you have to do is set your spell gems to a keybind on your keyboard. Mine are the numberpad keys 1-8. Then you need 2 Cannibalize spells, Canni1/2 work.

I have canni 1 and 3 set to my first 2 spell gems (number pad key 1 and 2) and I use a spyglass to refresh the global cool down. I have the spyglass in a main inventory slot that I've made a hotkey for on my hotbutton bar(the 0 key hotbutton.) Cast canni 1, hit 0 key for spyglass, immediately hit second canni spell. Works great to get mana up quickly.
