I've learned a fun fact about Sohei Flurry. If you have Weapon Training from Fighter levels, you can flurry with any weapon you have Training in. So essentially a 1 level dip in Sohei gives Fighter multiclasses an extra Full-BAB attack (and extra feat + other monk goodies, such as Wis-to-AC).
Nice find!
Do you think Sohei 11 is worth it for an archer? I'm thinking either 4 Mutagen Fighter/1 Demonslayer/2 Eldritch Archer/11 Sohei/2 Deliverer, or 5 Mutagen Fighter/1 Demonslayer/2 Eldritch Archer/1 Sohei/11 Deliverer. Both Angel.
The 11 Sohei version has 11 attacks, 7 of these are at full BAB + Manyshot. But the 11th attack would only come at lvl 18. Until then it'd have the Ki Extra Attacks.
The 11 Deliverer version has 10 attacks, 6 of these are at full BAB + Manyshot. But it has 5 more AB and 3-4 SA dices.
Well Sohei also gets extra Ki Attack on demand. Still, I'd probably go for more AB and damage.
Yeah, after some testing, the Deliverer version looks to be the better option - much much smoother damage output progression. 1-2 attacks fewer in the end but better time overall.
Sohei version still needs Weapon Training for the extra attack to kick in, so I'll have to start with Sohei for 6 levels and deal next to no damage, then get mutagen, then Eldritch Archer, then Sohei again, then Demonslayer. All to get one extra attack at the end plus another one on demand. Deliverer version gets like 6 or 7 attacks at lvl 8.
What about Hammer the Gap? Can it be good with so many full BAB attacks?
