I am very unfamiliar with the current economy and not sure if this katana is even desirable but here goes. Supremely Accurate, Massive katana of Power. Starting bid-5k I guess. Feel free to ridicule me if that start bid is outrageous as I have no idea what people desire on this shard.
Generally speaking people are really only after slayer weapons. You can make decent money if you sell large bags of power/vanq weapons however. I wouldn't bother listing a single power +25 Kat. Unfortunately with the shards age that means that smith bods are very abundant. The special runic weapons that come with them are just as good if not better than most magic weapons.
I love powers and vanqs for farming mobs and even someone who is just starting out on pvp as a dexer....just because it won't be a huge deal if you die and lose the wep. imo
