+3 fire staff crafting

Given that you can scour the suffixes with a level bench for 2ex, you’ll probably save currency using that method; however, you might have a potentially unwanted prefix with your +3 staff.

Alternate method 1: (edit, might not work, see note below)
1. Alt spam until +2 fire (best if there is no suffix, but if there is it can be removed later see below). It should take 118 alts at 75% confidence or 197 at 90% confidence. A bit more if you are unlucky.
2. Regal prefix. If it's a suffix you'll need to scour start over or remove the suffix (see below)
3. Continue with instructions posted by woods above (ignoring the part about crafting flat mana since you’ll block your ability to exalt +1)

Total cost: ~200+ alts, 1 regal, 3ex, 5 blessed, scour. You can then re-add multimod and craft the suffixes you want.

Alternate method 2. (Edit: this might not work either)
1. Alt spam +2 fire (with or without a suffix)
2. Regal suffix (if you get a prefix, scour and start over)
3. Add prefixes cannot be changed (2 ex)
4. Scour (not on the bench). This will remove all the suffixes. (Edit: this will probably turn the staff blue, ruining this method. Sorry).
5. Continue using Wood’s instructions.

Total cost: ~200+ alts, 1+ regal(s), 5 ex, 5 blessed, 2 scours. (Add 2 more exalted orbs if you want to multimod 2 suffixes)

Another alternate method was posted by SisterShaniqua which is fairly similar but will cost about 2 ex more (2nd link above).

Happy crafting (at least until this method gets nerfed).

Edit: alt method 1 might not actually work as added mana is probably neither attack or caster, and this could roll with the exalt. However, alt method 2 with a regaled suffix should work. Staffs with item level exactly 55 might be better off with the regal method? I guess it will depend on if you can hit +2 fire on the regal in less than 2ex worth of regals.

Edit 2: I think neither method will work due to the issues I wrote about above. Rip regals :(
