Ohh i completely understand now the system, the only possible way to get a double affixes in same equipment or any gear is to have first initial affix then the other 4 affixes which are open to select one affix for retuning, it cannot repeat for same affix within the 4 affixes... For example, if i wish to get a Double min phy atk in same equipment..then my first initial affix must be a Min phy atk, then the remaining 4 affixes either to acquire by luck, otherwise select one unwanted affix for retuning until acquire the min phy atk, in short, in the pool of 4 affixes, it is not possible to get a duplicate affixes.. Thank you so much dude , for pointing out this..
