i calculated it out and a book of abyss with a 5.5 min a1-a5 clear time + 20 min omega clear time itll take 10.5555555 days and i think thats way too long to leave to chances so i was thinking itd be cool for this and a few future items possibly (i dont think fm is hard enough its like 12 hours with 1 min games)
so the idea is that 1 frag drops off rez every time and when you get 5 of those you combine it to a 5 frag and 5 of those make a 25 frag and 4 of those make a book (5-25-book so it doesnt take up so much space) this makes it so if i wanna waste the time getting it i dont get beaten to somebody with more luck then me
another idea was that in addition to the chests you get something that with the next frag set itll automatically give you the portal maybe move the odds back to 1/4 if this is to op sounding
