Edit: answered, thanks!

These 2 crystals are all I need to complete my pet's treasure chest: Magma Defense Eye of Royalty Crystal + Magma Eye of Royalty Crystal. They're both super expensive unfortunately :(

I'm guessing they're super rare, but where can you get them?

According to Subetalodge they're from defeating the mage 25 times in battle!

The Mage is an Impossible challenger in the battle coliseum, and he is one of the toughest of the Impossibles. I have a pet in the top 100 and I can't win against him that many times.

It's not likely that there are that many of these in all of Subeta. This is why 's price is reasonable.

Alright, thanks!

Oof, I better start saving up then =_=;; thanks!
