As a bsm i've been desynthing quite a few ifrit weps in hopes of getting an inferno demimateria. But the problem is that 5/6 times it was successful but it only produced 1 or 2 earth and fire crystals and the ocasional 3rd ingot.
I was like whatttttt no way.
My only other assumption is that the demimateria would be produced from ifrit ex drops. :/
Sighhh lol jokes on me!
