Celtic Heroes

Hi mages,
I am new to the mages class and was wondering if I could get some advice on skills. I am currently a lvl 56 fire mage with most of my stats in focus. My current build right now is:
Fireball - Maxed
Firestorm - Maxed
Energy Shield - 4
Lure of Fire - 10

I'm working on getting Incinerate but don't know if it's worth using since I don't seem to see many ppl use. Any advice would be great since I don't really know much about mages. I don't mind changing builds and hearing what everyone thinks. Thanks

If you're looking for a 5th skill, go with Fire Attunement

Fire attune is almost as important than fire storm, you should have them all maxed though.

Incinerate sucks.
