Need help further crafting this talisman

Is the next step a yolo fracture hoping for 25% chance to seal melee skills? Correct me if I'm wrong but 4 scenarios here:

-Doesn't matter what it hits and I hit crit chance/crit dmg/atk speed and guaranteed desecrated atk speed.

-It hits +melee -> Perfect exalt, if bad suffix -> Omen of dextral crystallisation+perfect essence of haste and guaranteed desecrated atk speed

-It hits +melee -> Perfect exalt, if bad suffix -> Omen of dextral Erasure, until it hits a good mod and guaranteed desecrate atk speed (Whole lot more expensive)

-Doesn't hit and I settle for bad suffix + desecrated atk speed

Would appreciate any help
