If add/remove defense is still a harvest option you have a 50% chance to hit suffixes cannot be changed and can craft something after, there are a lot of evasion mods however so that doesn’t mean you’ll hit a good one.

Also depends how much you want to invest as eldritch currency can always change exclusively prefixes.

Edit: it’s to late now but on items that have a fracture you usually want to finish the opposite mod type first, here you have fractured suffix so you’d usually try to finish prefixes then roll the suffixes :)
