More of a Question instead of Pc but plz take a Look

Hi, not sure if this is this is the right place to put it. but it is about items so i guess this "might" be the ideal place to post this. If is not, sorry, and would greatly apprieate if one can direct me to the correct forum for this.

the question is: do platinum skin weapons such as platinum blade, platinum wand, platinum staff, and bow drop in nightfall or is it a fractions only item. (so i know not start looking for those platinum stuff in nightfall and look like a complete noob ).

while i am at it, are there any other skin that dont drop in nightfall (where it can have the inscription thing). to my knowledge the items (skin) that i know dont drop in nightfall are: zodiac skin, gothic skin, magmas shield, mursaat bow/hammer.

plz correct me if i am wrong and thanks in advance.
