Null Stone Rod- recraft cost?

Can’t find a way to preview without owning the item and attempting a recraft.

Does anyone have one of these to see what recrafting takes? Tempted to gamble on it with cheap mats and no missive, but not if it’s going to take another 5000g of mats to improve.

Edit: NM, got my answer.

Costs 1 ingot, 1 null stone, and 50 dust.

Really glad I didn’t cheap out, recrafts are almost as expensive as a new item now.
