How would you allocate stats here?

18/14/12/12/17/7 motherless

Something along these lines? I feel like I'm missing something or doing things out of order, like I think I could allocate Slayer to a better position to try and cheat TWF feat easier. Should I add combat maneuvers to make it more like your Trip Vivi build?

Race: Tiefling (Motherless)
Alignment: Lawful Good

Stats:
Str: 18 > 22
Dex: 14
Con: 12
Int: 12
Wis: 17 > 18 @ 20
Cha: 7

Looks alright, although you don't need TWF feats anytime near earlygame. Backload those pretty far back into the teens - you'd want to use staff for some time anyways and there is only one actually good double sword to care about, so I'd just chug along with a staff for quite a bit. And you can grab some actually good feats like shatter and crane. I also see no compelling reason to get dreadful carnage since you'd likely want a dirge bard anyways. I'd probably take deceitful and intimidating early.

I'd also get wis18 at 4 as that's a welcome AC boost where it counts. And you don't need improved crit at all since twin crystals are keen. Another option would be to start with wis 16 and dex 15 with much the same effect. Would be slightly easier to take TWF feats, I guess, but will saves are more important, so it's whatever you prefer.

Cheers man! Yeah and you were right it's going to take a while to get to the twin crystals. I need to think about this doubly, though playing as a tiefling seems intriquing as I haven't done so before.

Edit: An additional question, how would this build fare until acquiring the late game weapon?

New player here,

I was browsing through the builds, which are awesome, but i was wondering if there is something about a dwarf melee front liner.

I really like the dwarf fantasy but from what i read their stats are not that great for higher difficulties. Is it possible for a build of dual wield dwarf killing machine or an already existing one with modifications for dwarves ?

Got the dlcs etc.

Just a quick question

Whats the earliest decent Greataxe to switch to from Quarterstaff?

Vanquisher. Since you can get it at level 9 give or take. Barring that, just hope your artisans bring in something decent. There are like 4 artisan greataxes and all are not bad.
I mean you can take the v16/M1/Slayer3 build above and it'll be ok on a dwarf, just with slightly worse stat spread. Dwarves in general just don't offer much to build upon. Humans get a feat and can dump int, Aasimars get the most stat total and wings, motherless gets an extra bite... Dwarves just don't get anything special to build on and dwarven weapons are unimpressive to say the least, so that part of the kit is out. And dwarven speed thing is totally useless. They are usable if you think of them as bad tieflings or something. Guess you can say they are ok-ish clerics except humans are better... and ok druids, but the humans are better(and can be master race feyspeakers).

Thanks a lot for your quick input! I will give it a try just for the fantasy

Thank you!

How badly does Valerie Bard and New Amiri build overlap in gear? Like I saw Gyronna does and I wonder how well they will do if I only give it to the person who needs it more.

Also Will Amiri be fine on Hard/Unfair with the build? I really wanna take her with me once for flavor.

Or am I misunderstanding here and she's more of a 2nd row damage dealer with that build and not an off-tank?

Bard val doesn't really need gyronna and paragon. Those are just BIS. Amiri kinda needs those. Off-tanking is somewhat of a meme and regardless of what you do she'd need to have good AC. Give or amiri val Shiny helmet instead of paragon. And gyronna... Val will be ok without.

Thank you. Was more concerned if she can actually hold the line. I just said off-tank because I wasn't sure what to call it.

That amiri kinda has better AC ramp than val does. At least once you get the oak after vordakai and should be roughly equal before.
