I know they can stack, but have not found any indication that an effect has reach the maximum bonus. Any info is appreciated.
Hey im not sure I 100% understand you. But I’ll try to explain what I know. Normal and Sacred items can be tempered with 1 effect, Ancestral items with 2 effects. When you put the effect on, in the lower part of the screen it tells you how many tempers you have left on the item (when you did it once). As far as I know there is no way to see before tempering. Hope this helps!
