Based off of the Description of Sword Polisher I believe it should be reducing the durability drain of the Melting Curse, however it does not as far as my testing has shown.

How to Replicate: Simply equip a Weapon with Melting and have the Sword Polishers Trait active, it will not reduce the Durability Drain when the round turns over.

Durability consumption reductions don't apply for melting, so this is intended.
