who to ultra evolve

Well got my second omegamid, going to have to grind a crystal mouth first but…

Sheildwyrm
Rexo
necrowing
Guardiron
Angelon

Don’t really use my others. Thinking one of the top 3 really.
Shockingly I found one in the first try I went in and it killed itself with survivor. Disaster

It has been two weeks and i’m still searching for my crystalmouth for rexo… Pitty I used the one from the challenge on another legendary.

Literally after I posted that first battle I found one, couldn’t believe it killed itself (I’d not actually encountered one before, didn’t expect it at all).

Do they ever come as rewards?

No you have to catch it during its appearance. gold one is always the reward

I meant in events.

I have no idea why people struggle on this. I literally went in like a week ago to farm 4 for whenever I need it. First run found 2 in the same fight and caught both. Then took me like 3 runs to get two more because I couldn’t catch them all but they show up so often

I’ve only seen one.

some ultimate challenges do have the crystalmouth as a reward

Did crystalmouth so hard to catch ?
What monster use that as ultra material ?
I would go for aegis(shieldwyrm)
Or go for t-rex

Well, the crystal mouths come along a lot but, most of the time actually. But the catching does it, he will kill himself with survivor or escape from the capture card and it pisses me off.

To actually answer your question…I’d do Rexo or Shieldwyrm. Then the other, then angelon, necro and guardiron

If you have offense already then shieldwyrm. If not then rexo. And the crystal mouths all come down to luck.

Thanks for replying topic kinda went off track haha, pretty much what I was thinking.

You find them quite frequent ? I’ve literally seen one and I’ve done it quite a lot. Probably wouldn’t catch him anyway but when he used survivor n killed himself really pissed me off. Had no idea what moves he had.
