I went back on my breeding criteria because I realised I had
247 cooldown potions in my inventory, and a perfectly good QB Emerald male and SB Ruby female... I have 79 potions left as of this post, and out of 22 offspring, 8 are Sapphire Wyverns.
Not the greatest odds but I was able to brute force my way through due to prior investments years ago.
Also realised I have a totally unrelated G1 Sapphire I bought recently, so I now have a good pair for even G2s. Now to decide what to do with the rest.
