Are there any NPCs that sell Lv. 90 armor?

Title.

I just made it to Lv. 90 on my Thunder Breaker, and I was wondering if there were any NPCs that sell Lv. 90 armor, as I'm still using Lv. 70 equipment. I don't have the money to craft them, so... Yeah.

Thanks in advance.

Not that I know of. Level 90 equips drop from monsters. Try Monster Park, primarily, because the equips there have hidden potential and you could get lucky with the stats.

Good luck.
