What we don’t know yet

No wiki publishes the dust cost of each polish or the exact numbers for each accessory at +1 and +2. Some guides mention a third level on certain accessories, and New Game Plus has more polishing steps. We will update this as soon as it is confirmed.

Which accessories to polish first

The ones you will always wear: the two key accessories of your build. Since polishing is irreversible, don’t spend crystals on situational accessories like the Flameward or the Thunderward.
