Final Fantasy XIV's lodestone has all the details, and apparently the Ifrit encounter comes in two distinct flavors. One is designed for level 30 light parties (four members), while the other is a hard-mode run intended for eight-man level 50 groups.
Ifrit wears his badassery on his sleeve if the accompanying video clip is any indication, and the lodestone entry describes him as "a demon spawned by the seven hells" whose exhalations "produce heat of such torridity as to reduce iron to pools of white-hot liquid." See for yourself after the break.
