I used over 113 arrows (I’ve been counting) and I’ve never gotten a single shiny which makes no sense at the 100 arrows mark I should’ve been guaranteed at least one shiny (the only good things I got was TWAU,SPTW , and SF)
I mean, atleast on my school percent means how likely it is to happen, if it has 1% of happening then if you try it 100 times it should do it, but it isnt always happen its just really really unlikely to not happen. you are just really unlucky lol
