Crafting way forward - +6 staff with spell damage and crit chance

https://preview.redd.it/a1r5ilwtb2kg1.png?width=725&format=png&auto=webp&s=867b7d7f6520a93adaee2bcae8d7f633773eb3f0

1. Got +6 and spell damage with recombination ( will div it later for +6)
2. blocked mana with desecration
3. perfect ex for t1 gain got lucky
4. light and annul - mana

Where do I go from here?

Desired modifiers

1. Prefix: another gain/ cold damage or lightning damage - wasted a lot of lights trying for spell damage that costs life without knowing that it is in the same category as increased spell damage
2. Suffix: at least t3 crit chance since I could have gotten it from greater essence. Not very particular about the third suffix (open to suggestions for COC comet spark blood mage with choir of the storm)

Budget: have 800 div in stash and may be can spam Atziri for another 500 div maybe.

Thanks in advance, kind souls
