More plamdest?

Hello! So I am trying to farm plamdest for a rivalte rifle. Is there any way of getting more out of the 14-15* weapons? Maybe use a great success +50% or something?

Thanks!

If you have tons of RWB5 and UWB, you ciuld exchange them for ★14/15 weapons. If not then you could always run Craddle of Darkness and dismantle the Ares weapons you get, though it may take a while.

Alternatively you could run Final Lament UH and pray for a drop, you can transform any Rivalate weapon into any different weapon type as long as it's +35 and you have 999 Goldest and Sapphard.
