I had an offer for a butterfly water wings, and it was a pair of elegant butterfly wings. I'm not sure if that's fair, even though they're both promo. The elegant butterfly wings are sorta common, and I'm not so sure about the water wings. The common item worth wiki says that the elegant butterfly wings are worth 2-5 den betas to a good long wrist; the butterfly water wings 3-4 den betas to a bad long wrist. It's kind of confusing which one is worth more. I mean, you could guess that the elgant butterfly wings are worth more because the maximum worth is a good long wrist while the water wings' maximum worth is a bad long wrist. But I don't know. Any help plz? Thanks.
