No... what..? In 10 pulls..? What..?

I spent around 170 pulls on Odette to get her, but her exclusive weapon dropped in just 10 pulls..? No... what..? I was about to spend $119,000 won because I thought it wouldn't come out... I only had 30 minutes left, but I thought I'd try pulling first and then recharge... and it came out in 10 pulls.. what..? Is it giving me the weapon nicely because I got screwed over by the rate-up and pity on Odette...?
