His sheet isn't ready, yet. We'll put it up on Obsidian Portal when it is.
There will be a lab ready in Autumn 1220.
You indicated you read all the threads and are up to date. You're missing something very important in your analysis. Aegis must penetrate (if you want the warding effect). It's RAW and I subscribe to it. And yes, it underpowers Aegis, but it also makes Wizard's Communion a necessary spell to almost any Magus who can get to 3rd Magnitude MuVi.
If it were the case that the spell only needed to be cast, then anyone already here could do it as shown here.
