Frost dome does stop spells? Hm, I'd thought it was merely the counterpart of the Fiery Death dome. *shrug* Improves it a fair bit, then.

Shield of Valour gives the air shield, as do the robe and (token? amulet?).

Other note: facing astral nations, try to keep at least one or two astral mages co-located (for stopping Mind Hunt... which may still be tried by Arco c/o the priestesses unless you have a dome which kills them). Against all sorts of commander-hunting spells keep numerous scouts.
