ASH is Ancient Smith's Hammer, and it
does increases your chance of success with enhancing... If you've been playing nine years, and don't know this, it's probably just that you don't move in Trammie Smith BOD circles like me!
Here's the
Stratics Enhancing calc with the stats if you're interested. If you enter in 255 durability, it will even show you that the resulting piece will be more than 255 if done this way, and it also shows the increased success with an ASH.
Anyway this does work, and have a few items over 255 durability done this way. It's not really needed, and most people know about it, but I will yay this as it could be handy for others. Little
Yay from me.
