I always wondered why these supernatural creatures would have weapons and armor desiged for humans in the first place.
Ifrit would be like "Yes I have this incredibly powerful bow specifically designed for you mortals but NO YOU CAN'T HAVE IT YOU FOOLS. Me likez shiny stuff."
It's like with dragons and treasures. If I were a dragon I wouldn't hoard money in a cave and live in it. I'd have humans build me a giant aery with chocolate fountains. Honestly.

Anyway I think the weapons are fine, some of them could use a bit of downscaling though (like the bow).
