Thanks for the great suggestions.

When I have time I'll go back and revise them.
I thought about doing a few that granted feats. I had crystals worked out for the Two Weapon Fighting line and the Power Attack line, but decided against it.
I may do them anyway and let you guys decide whether they're good or not.
Honestly, I've never been a big fan of the Witchlight one. What do you think the Greater version should do?
