There is this link that lets you loop instance items back to its based stat. It also removed diamonds as well since ive done it before.

So does anyone know how to properly do it on other eqs besides instance?

I have a lord gown and a heavy spear with bad diamonds and i would like to remove it using alchemy.

Books are hard to come by so i rather not make another one by scratch.
