think it for access to floor 100

I now know what all for .On the 90th floor you go to warp and you have to have this badge to go to the 91st floor. You then walk up seemingly no monsters until level hundred. Then I saw the mighty reeper and he surprised me. I was not prepared for him and he is one tough dude lol for lower teer anyway.I would not suggest you go up until well equipped and ready for this dude.He comes from out of no were.So always walking around have crystal etc or most lower teer
players especially under hundred be doomed likely. The badge is reusable
