Ifrit requires quite a few crystals and followers to be summoned if I recall. I doubt one person alone could summon a primal. You'll have to remember it was the beastmen TRIBES that summoned each of the primals, not a beastman. Also, the people who summon the primals, follow the primals. I doubt Ifrit would be willing to follow you or let you ride him or he would lure you close enough and shred you.
