Astral magic adds to MR ???

Yes, it is in manual. In fact, I thought that every level or two in magic increases magic resistance by a point or two. However, that is what the manual states. I don't remember the page or have my manual available, but it is described in the same section with spell penetration, before the list of commander commands IIRC.

I think Dom1 manual describes magic resistance as Izaqyos, and most of us others, thought it would work. It didn't always hold true for even Dom:PPP, though, so it might have been changed a long time ago...
