You may get some responses that are final fantasy-esque. You'll likely get more
'Summoner'esque responses where the summoner uses a summoning circle and summons up demons, ala planar binding, and gets it to fight for him, if he can control it.
As for Final Fantasy-esque type responses, there are two kinds.
1) Summon spells are more like cool flavored evocations, they show up, do a single powerful attack, then dissipate.
2) Summon spells summon a large monster, and make you (and oddly, your friends) disappear, until it is called back or defeated, a-la pokemon.
You'll notice in all of these cases, the Summoner has Multiple things they summon in the same sort of way.
Yuna is a summoner, albeit one whose personality I found grating. Yuna summons more than a single creature (She can summon something besides ifrit), she gains more creatures she can summon over the course of the game. Likewise for summoners in FF4,5,6,7,fft,ff8,and ff9. So this is not like a Final Fantasy summoner either.
It's like a specialized pokemon trainer who only has one pokemon. But the pokemon is really freaking cool.
Hence Eidoloneer.
