(CLOSE) I PC I OS Celestial Sword Q6 Max DMG

Entirely depends on the inherent mod.

Unid , i think xA.

Might check for +5En by equipping it unident.
If +5 Energy it will definitely attract some attention and should be mid to high xx arms, might even go triple digits if people get hyped
15^50 low-mid xx a
anything else probably x a, but I'm by no means a low req specialist...so might wait for more opinions.

unident maybe 100e-200e, hard to tell
