Novus weapon upgrade system findings

[Itseotle]

Something that is still unclear to me..my weapon has 4 stats, 2 main and 2 secondary stats. By upgrading to Novus, is it possible to add a fifth stat or better said a 3rd secondary stat? Or can I only replace the 2 secondary stats I have on it? I am not sure, in the quest they said something about 5 scrolls or something.

You can add any combination of stats that are listed on your scroll, up to a maximum of 5 types of stats. The number that they cap at will lower as you increase the variety of stats.
