Also, for MA Marignon, Harbingers are great thugs and A3 for 25 S pearls. Seraphs are A4 but expensive and late game. Grand Masters get A randoms.

Harbingers are incredibly useful to have around in any case, so you should probably always have a few around in the mid game. A few air boosters can get one up to A5 (you need a Ring of Wizardry to get them to A4 temporarily to give them booster making capacity), at which point you can summon a Queen of Elemental Air, pass over the boosters, and get up to A6 easily.

As LA Abysia, there are fewer options. Heavy site searching with, I believe, earth/astral mages can get random sites which let you hire mages that might have air.

Avoid empowerment like the plague. It is a terrible option in almost every case.
