Rolling with OMG Burgers idea, I created a skill mule and transferred 50 ninja to my sampire, stoning off anatomy. I have skill room for it, and possibly jewle room to make it a permanent part.
Using focus attack, I have seen that 50% is not effective so far. Perhaps at 67.5 (100% chance) it will be more effective.
So far, fighting bouras, I see a little damage increase, but my mana leech is non-existent. It will replace what I used, -2. But then again, high end damage is 47 without anatomy.
I THINK I can fit it in once I am done with suit pieces, we will see. Will report more on this later.
