PC on a jade sword, 15^50, req 9

Upgrades normally don't influence the value of a weapon that much so I would sell the +30hp seperetaly.

The jade sword itself, it's not that rare imo as a found a few in the jade sea. It's just a newly introduced weapon which is still a bit in hype phase. To me the skin looks like a toothpic so that might influence my view on the weapon, but it's what people want to pay which is important. I would start at 30k and see what you still get of interest.

80-100k

req8 15^50s are selling well for 100k10-20e, but this may wear off as the hype dies down.

If you're looking to sell, I'd sell while the skin is still fresh.
