I have a question about the upgrade levels and the white stones.
I have used a white stone in a few items(+7 +8 +9) and I have noticed that when the item "fails" it doenst decrease a upgrade level, but when the item "breaks" it decreases 2 upgrade levels.
Also I have seen some videos where they upgrade items from +11 or +13 to +15 and when the item breaks this doenst decreases upgrade levels.
(All of this is when you use a white stone obviously).
So my question is what is the upgrade level when the item can breaks and doenst decrease "upgrade levels"?
Thans for your attention.
