Voidwatch: Crystal Petrifact

[Byrth]

Also, there were a lot of requests to make it possible to exchange these items for Voidstones, but doing this would create the cycle of doing Voidwatch in order to save up points to do Voidwatch, so we would like to hold off on this type of exchange.

Petrifact -> Voidstone is just a more direct path between the two points than what you're proposing:

Petrifact -> Cruor -> Gil -> Voiddust -> Voidstone
