White Angelic Blessing

is it possible to have a legendary potential item like this :

STR+12%
STR+9%
STR+9%
STR+9%

Or can you even have all 4 lines of 12%?

Since this thread is about White Angelic Blessing and you quoted an aswer about it, I will asume you still ask about that item. So firstly, It has no slots, so it cannot have any potential. Secondly 4 lines is not possible on any item (but with Nexon being Nexon, it might get added sometime down the road).
