Pseudo-infinite Turning attempts?

[Chronos]

This assumes that limited-use abilities are refreshed by Shapechange, which is a hotly-debated topic. Though this is, I suppose, a less abusive use of it than Zodar wishes.

EDIT: Oh, and a base of 10 plus 4 from a cloak plus 4 from Eagle's Splendor equals only 14. The cloak and the spell are both enhancement bonuses, and so do not stack with each other. Though there are plenty of other ways to get a large enough pool.
