Bob, I'd argue that both Trakas and Lethiel would be highly familiar with the strengths and weaknesses of Air Elementals. Lethiel can summon them literally at-will, and Trakas can spontaneously cast<em>Summon Nature's Ally</em>and summon one with any spell slot 2nd-level or above.<br/><br/>Kunoichi, do you want to try talking, rather than killing? Lethiel speaks Auran, doesn't she?
