Alright, so i've been thinking.
I dont really use this girlie, so i'd like to trade her.
-Shes been named.
-Shes been bred.
-Shes been mutated.
-Only 6 Twilight Nephini caught.

I would be willing to trade her for wheel pet(s).
Not sure exactly what kind, But i'm partial to this wheel Ligh, and any wheel nephinis.
Also willing to sell her for gold/items/etc.

^{I honestly dont know her value, but i'd price her at 4000 diamonds, which is roughly 2 of the less common wheel pets.~}

Since she has been bred,named, and mutated, she might be around that area, but I am not too sure. That would be around 10m gold, which is a lot for a pet that is not a wheel pet. Though only 6 are in existence, so I am not too sure..

Shes a tagged wild Nephini, One of the first tagged Nephs caught, Tagged Nephs themselves are usually more then wheel pets price wise, and with only six ever being caught, it puts her up there.

I'd offer 2k diamonds.

Bred, mutated and named does not put her at wheel pet status to me.
I hope you can find someone to offer what you're looking for otherwise though.

Yes, I know she is a tagged wild Neph. But it doesn't matter if she was one of the first ones caught. And tagged nephs aren't aren't usually worth more than wheel pet price.
