Ribecca

So I was trying to do Ribecca's mastery and I just needed 1 more Ichor spills. So I did a solo run and I made it to floor 23 and still didn't get any ichor spills. So I tried again, but this time I played with my brothers, so we can do the floors a little bit faster, and because he's not good, he died on floor 10 and because I didn't want to play alone, I killed myself too. And guess what? I still didn't get any Ichor spills. So I decide to take a little break and played Eclipse. And guess what...I got a ichor spills on floor 4! (at this point, I feel like the game hates me)
