The build on Neoseeker is a little messed up so here is my own cleaner version. For one, some of the levels for feats are wrong, but also the order of some feats is weird. It picks up Dodge early on without going for Crane Style (but level 20 Stalwart?), and it picks a level in THF early for martial weapon profiency... which would be fine if it didn't aim for fauchards. Instead, why not just pick up fauchard profiency early and call it a day? You don't really need defensive feats if Jaethal is using a reach weapon, Combat Expertise really only gets picked as a requirement for Trip.
Also that build suggests picking up Seize the Moment as the first Inq teamwork feat, which I think is totally pointless. So anyway, things are mostly just reshuffled in this build. Grab a Masterwork fauchard from Oleg right away and don't think about it until you start getting better ones later in the game. Sure, she could be doing more damage if you gave her a regular melee weapon without Reach, but that makes Jaethal annoying to use since she's harder to heal than normal characters. Precise Strike is a nice damage boost on level 3 so it's not like she will be lacking damage, though that would also work with any other weapon type.

Why pick up Remove Paralysis and Boneshaker early here when I wouldn't do that in other builds like with Amiri? Because we don't multiclass and thus have those spells super early. Remove Paralysis is nice to have because the game does throw a couple of annoying enemies at you that just spam Hold Person - Remove Paralysis helps with exactly that. And Boneshaker is a decent enough ranged nuke for the early game. Not amazing, but still good to have if you ever feel the need to kill something from range.
