Such a spell would almost certainly be unbalancing if you gave it to *everyone* - although see below.

In this context, you have to consider the nation(s) that get it, and the research level where it arrives. Is it unbalancing for Marverni to be able to conjure elementals off of a NNA caster, which it doesn't get? If the best thing you can get out of your God - or a powerful, expensive independent caster like an Enchantress - is a lesser air elemental every turn, I'm not impressed.

I'd been planning to give the same spell to Man - for the specific purpose of making the (not, frankly, very useful) Mother of Avalon a little fiercer. It might be ungamebalancing, though - Man is not exactly a weak position!

Peronally, I think they went somewhat overboard nerfing the elemental summons. I never cast them. Same story with elemental horde - it costs so much fatigue that a mid-level death caster can only zap it once - if he instead spams a lower level undead summoning spell, he gets the same number of undead without spending any gems.

But playtest it a bit and if you think it's unbalancing let me know. These spells are intended to improve game balance as well as to be thematic, if they don't improve game balance there are plenty of spells I could add instead.
