You’re pretty stuck with mana regen.
You can sell this, and start over.
Fracture spell dmg
Chaos spam for +6 then slam for t1/2 cast speed.
If you don’t get cast speed? Annul and slam if you remove the stat you don’t want. If you remove +6 back to chaos spamming. Edit: omen Suffix slam*** not just a random perf ex lol
Do this until you have +6 and cast speed. I’ve gotten lucky on first try, and I’ve missed 7. Rng is rng. Then whittle/erasure your prefix. Desecrate for crit.
This staff is not worth a lock, as you can get back to this point for less than a lock. It’s the omen of lights that will get truly expensive going for t1 crit on the next staff.
No need to sell until you have a +6 with cast speed which you can probably get with less than 500d, but RNG can fuck you. So never a guarantee.
