But it's not a 'placeholder ball', it was what they previously said was the rarest type of core available.- the silver was was worth an absolute ton so the rainbow should be worth magnitudes more.
You could still be right, I'm not arguing that, just seems weird to me. Kinda like getting a draw of a suitcase full of loads of money, but then having to trade it in for the 'real grand prize.'
I'd understand more if they had a choice between the two, especially since a sword may not be wanted by some, where the core could be sold easily to secure a ton of money given how much it should be worth.
Again, not saying you're wrong, just some ideas about some of the other options that could be a possibility.
