EA Tien Chi: Rainbow pretender. Ideas?

[Balakirev]

I'm pretty new to the game, but wanted to focus on magic, first. Tien Chi seemed like a good choice for this. Any recommendations on how to create a solid rainbow type? The strategy guide offered a couple of examples, but nothing elaborate.

I'm also considering a strong move into forging, so please keep this in mind. Perhaps you can suggest paths to follow that will allow me to improve that pretender in my chosen path. In advance, thanks.
