HAX is pretty effective, but I wanted to try something new for a bit or go back to throwing. The reason why I priced it so high is because it's difficult to find looms that you want and often I'm stuck paying 450 per loom or so for items that aren't even MW. Looming crossbows and bolts is really the only way to increase the damage they do too, so I feel that crossbow looms are more valuable than looms on other weapons. Since it's masterwork, you also never need to risk trading it to someone else to loom for you if you don't want to loom it yourself.
For trades, I'm not taking as much risk about getting what I want, so I'm willing to tone down that cost a bit depending on loom level and such. I'll accept MW to MW trades without any extra gold.
