Unfortunately ppl can get multiple purple items from this promo so the odds are not great. Furthermore the purple slot is very diluted. Bringing the promo back so often ensures good supplies but it is a windfall system. In the history of the promo I have won once 6xpurple and it was Archers legs. I have never won the rare item promoted. So if you were hoping to make an easy 1 bill that is unlikely to happen but yet again you never know. That is why ppl call this gambling.
