How much should I expect to pay for...

... a fellblade, flamberge or longsword with the following:

Max Damage
+15-20% (while in a stance)

or

Max Damage
+15-20% (while enchanted)

I hope the conditions I'm looking for don't command the ridiculous prices the 15%>50% condition does. I'm trying to plan out how much gold I need to generate before buying more armor/weapons. Thanks for your help!

There is a collector's longsword that is max damage and +15% while in Stance (Stance dmg mods only go up to 15%). Don't spend more than 1K on it.

If you want a Fellblade/Flamberge with the same stats, plan on paying 20-100K, depending on how long you shop. But remember, you are only paying for looks.

A collector's longsword you say? Works for me. Do you happen to know where they are and what they want? I'll look around the net for the answer as well.

Thanks for the info!

Excellent. Thanks again.
