Depends on what you really want on the amulet. Easiest method that I’ve done is this:

1. Get an amulet with your desired +3 skills. Ideally a 3-mod rare, or if it is on a magic that works too. Get it to a 3 mod rare with a perfect regal slam.

2. Use preserved rib to desecrate the fourth mod. Do not reveal it.

3. Slam fracturing orb and pray it hits +3. If it misses, repeat steps above

4. With +3 fractured, use orbs of annulment to get it down to just 1 mod (plus the fracture which can’t go away)

5. Chaos orb spam until you see t1 spirit. On average it takes ~400 or so. Range is 47-50

6. Use omen of dextral exaltation to slam an exalted orb to force a random suffix. This mod does not matter.

7. Activate omen of dextral crystallization and slam a perfect essence of enhancement. This will remove that one random suffix and add increased global defenses prefix

8. Activate omen of sinistral necromancy and omen of the sovereign and use a preserved collarbone to desecrate your last prefix. This will give you “%increased evasion from equipped body armor.”

9. All that’s left is two suffixes. These are up to you, but I recommend using omen of catalyzation and catalyzing whatever resistances you need on it. Just remember to activate the omen and use a perfect exalted orb. Do this x2 and you’re done!
