Ifrit (Hard) Weapon drop rate is a joke.

[Amberyl]

30 runs;

Grimoire - 13 times, 6 times in a row at one point.
Claws - 7 times.
Codex - 6 times.
Bow - 2 times.
Cane - 1 time.
Battleaxe - 1 time.

Random is not random. Add to this the fact that the average Ifrit HM run has at least two, sometimes three Dragoons in it, then I'm looking at upwards of eighty to ninety runs total, presuming one actually drops in the next couple of tries.

Meanwhile, philo mats are selling for 40k a piece, and don't take much longer than four Ifrit runs to obtain. I might as well just go buy a Titan HM completion at this rate.
