Faith/Int players in SOTE, what is your spell rotation for PvE?

I respec'd and added a bunch of Faith and these incantations are fun as hell. I have no idea if I'm supposed to be using them all or pick a lane - experimenting right now.

What spells do you use around SOTE? I'm trying to find that confidence to venture into the wild like I did when I was a pure Int mage.

Is it ok for me to use fire, dragon, lightning, all in the same build?
