Thats the only way that the duro will go down by that much.
And no, you cant get it back to 98/98...ever...the most you can do is try to get the max duro blue, which is added by a Jade tablet of Master. Im not sure what the max increase on that degree of an item, but even if its 100% increase, your only looking at a max durability of 72.
Thats why you should use steady when going for more than a +4
