[Taqwus]

Air shield items also help against Seeking Arrow -- amulet of missile protection, or the robe (cloak?) that does the same thing, or a shield of valor (lovely item, that).
Even with missile protection, you still have to watch out for things like Fires From Afar (fire immunity; dome), Mind Hunt (friendly astral mage; dome; high MR); Earth Attack (combat power; dome), Wind Ride (size 6; earth magic; ethereal; dome; seriously ultra combat power); Manifestation (combat power; dome); Leprosy (high MR; dome), Flames From the Sky (fire immunity, dome), Murdering Winter (cold immunity, dome) etc.
