R35+ formula

Yeah I spent about a tricorn a level at the end of GS and BS. Well, 1 or 2 tricorns a level.
Your estimates are right.

At 40 you'll be 5 ranks below Steel Awls (made from 3 steel nuggets(made from 2 bomb ash and iron nug mats). This route is expensive in fire crystals, and the bomb ash you might be forced to farm(nanawa mines 25% rate, I did 150 in 3-4 days), but it pays off through 40 and 41 especially as you get 400-560 per synth with good success:fail ratio. If when 5 below the target synth you use optimal craftsmanship stat and maybe smithy's gloves for control stat, you'll have a great time through those levels. Then at 43 silver javelin heads will be much friendlier to skill on.

I'm sure this route was probably too expensive and I just didn't realize it. I solo'd levels 21-23 on marauder farming the ashes, so it really wasn't bad to farm so many ashes. I would leave the area alone for a good 30 mins then clear it out again. The only competition i had was players on the quest from limsa cooking guild that sent them there to kill 8 bomb embers. I learned how to ask them very quickly and party up if that was the case. Also noteworthy- steel awls NPC for 3,420gil each. I ended up with 2x Steel Awl +1s as well.

edit: looking back, I am glad I did steel in the early 40s, however, it is a good thing I didnt stop farming bomb ashes - steel round knife blade (4x steel nug+1wind/1fire crystals) is the 300SP recipe when you're 49.
