I have 10k Gems. What should I spend them on? Details Inside!

Hi everyone,

I am Lvl 41 Kiki and have 10k gems to spend.

I was wondering what you all recommend?

These pics are my gear, costume and skills:

As you can see, I've purchased 37 skill points (total of 77). I have an immortal weapon, but only Rank 1. My armor is OKish, and my costumes are OKish.

What do you recommend me purchasing with 10k gems?

Thank you!!
