I was curious about how much it costed (how do people find out anyways?).

But cripes, 11k gold? With that dough (and a decent amount of patience) you could get 2 rainbows of mostly your choice, and a plausible chance of more golds (and maybe even more rainbows!). And you'd still have 1k left over.

You'd have to be really, really dedicated to Cactace to bother with this one. And you'd be 2-timing her with...herself?
