Right, Zeroth, Kreszenz will have asked if there was any restriction towards working with other applicants or taking multiple of the Harry Potter balls.

Also, eyeballing the crowd thus far, how many ball-wanters are there?

There's no restriction towards working with other applicants, but only one applicant can be counted as "in possession" of a winged ball.

There's no restriction against taking multiple winged balls, but they must be held within the hand, not solely by a spell, bag, etc. If you had a vice grip you might be able to hold two of them in one hand but it'd be difficult.

There are roughly 350 applicants.
