Hm... Maybe to level 3...
Level 6...In terms of filling up dead levels, two ideas have been had! First, some kind of synergy between boosts and minor formulae would be nice. They both eat up your swift actions, and such a feature would really set this apart from the sublime shaper, which has to juggle both.
And level 9...Secondly, it would be really interesting to be able to adopt certain formulae as stances. I'm thinking that the requirements of the Persistent Formula metashaping feat would be a good guideline on that one.
Well, most likely with these ideas alone, it won't feel like Shaper Lite.I'll keep thinking. It's a good idea to have a generalist prestige class for this, and I want to make sure that it doesn't feel like Sublime Shaper Lite.
Yeah, I'll write up a revision using those ideas. That should be just about right for this as a generic class.
