How should i raise my damage

Loveless weapons comes from Chaos Pink Bean, or gashapon box events/Wheel of Marvels. You are in Khaini, there are a few legit FM sellers who sells them for pretty cheap.
We also have a certain pair of brothers who sell them, but if you care about ethics, they should not get your business.

While there is the RED event I think i will wait little bit so price will fall down but how rare is Nova equips from the helisium boss?
