People often forget about this little quest, but if your alt is above lvl 75;

If you forget what its like, you kill one normal toad and its over...

This one is great for todays daily 'Complete a Battle 0/5'

I think @BloodAngel said it best.

These boxes are gambling so spend whatever you plan on 'losing' and if you come out a winner +yay. If you happen to get nothing, don't be upset at the game designers.

I myself bought the 11 pack on the first day and got a hell fairy pet on the 6th box. I bought 2 more packs since, totalling 33 boxes and after the 6th box I got nothing of any value.

Don't walk into the casino with more than you can afford to lose.
