Got bored (landline broken-no "Stranger Things" for me) so I started test run (without Weal). Went with bm/skaen aumaua/raider
Maje(max mech/hylea bounty/adra potion)->Meryel(she walks fastest, lure her out with traps)->Sandswept(4800xp)->Deadlight->Dunnage(Irwena)->Neketaka(retrain in gullet for max stealth/spechulars done/stole everything that wasn't bolted to the floor/ every drop of xp, even hire Rust to kill Spindle-1200xp bestiary/kept effigy husk and bought mantle 7 bolts and skuldr ear(!)->new ship->Hasongo(reptile blood!)->Beina->Dunnage->Crookspur(free wahaki/kill Dhwrgas)->Sayuka(half cpt banquet)->Ori o Koiki(brutish blood!- enchant effigy for AoE)->sayuka(captain banquet)->Bekarna(cape and rest)->Onadere->Ikorno->Vessali
all bounties were done from stealth with kamikaze phantom (effigy&7bolts)
I tried to do Poko Kohara (lv15) but culdn't
went Tikawara(natures resolve)->Nekataka->lv17 :)(giant grub, water dragon), killed Arkemyr(still brilliant from cape after dragon fight, attack first ironclad and only corridor agrro then send spirit ally for spell target practice for Arkemyr)
19 days till Ashen Maw. Ideally (I think) next Poko Kohara->Concelhaut->Nemnok->Belranga->Ashen Maw (I would have north covered, Auranic last) but I have doubts that I can kill Belranga pre lv19 (no wall of draining), rest should be easy with cape and arkemyr departure.
I don't think I will have will to practice all fights with notes and stopwatch and do Ultimate so maybe it can help somebody.
Edit. Just realised that while replaying post Crookspur to figure out how to get cpt banquet I forgot to take master navigator so it should be faster than 19 days till Ashen Maw
