^ the condition of said dagger directly after exiting a fight.
My offhand is also an Ether Tsukikage, but it's not Rustic. Its durability repairs like normal.
The main hand is not repairing, nor is it benefitting from the Maintenance talent, it seems.
EDIT: After the next battle, it appears to have repaired itself just fine. Still, I wonder why it didn't do so the first time.
