You see parchments all over Asulon.
"Hello, During my life, i have learned how to master material combining. After many experiments and other attempts. I have succeeded to combine obsidian and diamond gems. Now after several years i have found the material that i made, And i crafted it into a pair of boots.
It made the boots very light, There are straps so that anyone can wear them, but they are probably best for those stealthy shadow knights.
I am now selling this pair of magnificent war shoes, Its the only pair in Asulon.
Auction: Bidding starts at 25,000 minas.
Rules: Every bid must be 500 over the last one.
Edit: The boots are enchanted with feather falling I yes.
