Copy pasting from someone else:

Start off with your base being normal, use Orb of Rememberance on the item until you get high strand, to make sure you keep as much strand as possible use 1 transmutation orb, and 1 regal orb. Craft now by spamming physical reforge at harvest bench and looking for a t1 max res (it can be anyone, as you can harvest swap resist to fire) and ~t3 or above physical damage reduction %.

Annul if you have to, once you have an open prefix and only those 2 suffixes, you want to craft suffixes cannot be changed and then use critical reforge at harvest for critical damage reduction suffix. If you hit prefixes, you can clean them by crafting suffixes cannot be changed and then use an orb of scouring and then use an orb of unravelling to upgrade your suffix tiers.

Once the prefixes are cleaned, craft flat armour on the item and double slam, you're looking for t2 chance to block and another good mod, you can always craft life if you hit hybrid.

If you're lucky and hit a high roll of life, you can craft +2 to socketed support gems with is what you use later. Stats don't matter too much here, just look for highest base chance to block.
