Air bless: useless?

[Micah]

It should be noted that the MR portion of the S bless doesn't apply past MR 17...not sure if that can be gotten around by making sure the bless goes off before the antimagic spell or not, but it might not combo that well with astral magic (partly dependent on sacred MR, but most that are worth blessing are 11 or higher, so at least half of it would be wasted, Jags being the notable low-MR exception...hunter spiders too, I guess), much like arrow fend and the air bless don't get along.
