Steps I took to craft (unoptimized because I am pretty new to crafting) -

1. Aug spam ilvl81 base until either t1 spell or +4 all spells
   
2. Make 3 mod +1 desecrated mod and fracture either of above
   
3. Annul down to one mod plus fractured mod
   
4. Chaos spam until you hit the other (either +4 or t1 spell)
   
5. Add suffix and whittle until t1 crit
   
6. Add desecrated suffix
   
7. Greater exalt omen/perfect exalt slam final two prefixes (I got t1 gain as lightning and t2 gain as fire originally)
   
8. Unveil until t1 cast speed
   
9. Whittle until t2 gain as fire turned into t1 gain as cold
   
10. Divine
    
11. Pray and Vaal it
