3 Thief
6 Fighter (two weapon fighting)
3 Gloom Stalker
I was trying to calculate it ...
And unless i forgot something, it seems like you got to aproximately same Damage as you would have with Rogue on lvl 12 ...
Therefore there are two questions that radicaly affect this build imho:
- Will it be possible to deliver Sneak Attack with Off Hand Attack?
- How often will you miss?
Personaly i lean more towards builds where you try to make the strike count, rather than get more atempts to strike.
