How far off are you guys? With some coordination, it might still be salvageable. Otherwise you have to wait for the phantom UE as Dejnov mentioned (but that means you won't mlb/flb the axe for that UE.)
You can brick it I suppose, but I think bricks are better spent on good triple-skill weapons instead. Until you can start clearing GO consistently, it's not like you have the ori to FLB anything anyway.
