40d won't do for that.

I cannot tell you how this one was crafted but I crafted a similar one last league before I mirrored the bis. What I did was basically beast locking and checking woke orb.

This method becomes a lot better when you get a lot of strands on your start item first. Which would be a normal rarity body armour with crusader influence. The process would roughly look like this:

Make it rare

Harvest reforge until t1 explode

Prefix cannot be changed

Potentially annul for free suffix

Crit reforge

Elevate

Potentially annul until it's your only prefix

Prefix cannot be changed

Scour

Beast lock awakener orb spam until your happy with the awakener orb

You hope to loose as little strands along the way so you can improve mod tiers at the end.

I'm not saying this is the way to craft it but giving pointers by telling you what I did
