What should I bind with dragon keepsake keys?

I have 3 left, I can't get Primal or Prom. Shoot some ideas on stuff to bind my way, 30M budget.

Thanks in advance and please no spam

 

I would say something really random from like a quest, I was going to say the rocking out outfits but apparently you cant take them there. Would be cool if you could do the penguin form and actually walk around as a penguin.

 

I am sorry if I am kind of newb, but what is exactly dragon keepsafe? If someone can explain I would appreciate it

 

bind monk robe

 

i used mine on fancy boots and my flaming skull.

 

I'd keep it until you can get a primal drop, and wear that. What's the point in wasting it.
