Ive looked around on the spells of the amethyst order wizard and compared to many of the others it seams hard for him to be a full time mage since his spells isnt that usefull at all times, they lack in proper demage spells and such so thats why I was thinking about a Fighter/wizard Hybrid!?

Do you think this is a good/bad idea and pls why:)

Also how would you build them?

Any response would be very appreciated.

I would do the same thing that other non-combat characters do: invest in skills.

Why do Amethyst wizards need to be good in a fight, anyway? I'm assuming that if you want to play a wizard that melts people's faces, you play Bright. You play Amethyst to be dark and moody, unnerving people by whispering them the secrets of the dead.
