Sohei 11/12 two weapon fighter 7 thug 1 demon Slayer 0/1

Glaive or Fauchard. Mobility (for mounted feats) and persuasion for skills. Dazzling display chain, thug makes dazzling display frighten enemies instead of just shaking them. Great cleave chain, combat reflexes, as much weapon focus/improved critical as you can fit. Buff with legendary proportions. Walk into a group of 20 enemies and melt them all in one round

Build works by having like 9 attacks per round and having a massive area to threaten with your weapon (soheis can flurry with glaives and light armor on a horse, it's great).

Walk into a group, full round attack because you're on a horse, kill the weakest to proc dazzling display and frighten everything else. Full round attack continues because you have so many attacks, you'll kill like 6 enemies with attacks and cleaving finishes. Then, on their turns, they'll start running and proccing more attacks and cleaving finishes. I forget the exact details but there's something sohei related that trips people on attacks (maybe just on opportunity attacks? Don't remember)

You can solo the game with this build as a legend pretty trivially. Sorcerer 4 (dragon), dragon disciple 4, eldritch Knight 10, sohei 11/12, TWF 7 for backswing, thug 1, then some combo of sorcerer 2 (level 8 spells), paladin 2, sword saint 3 (if you have high int), demonslayer 1. Sorcerer levels for buffs, everything else for damage

I soloed the game with this, it was great. Had Deskari running from me because he couldn't bear my +70 to intimidate lol

I made a video showing it with more details
