Question about Sembian Fencing

[Teaboar]

I'm curious about how Sembian Fencing works when wielding two weapons. Does it take both main-hand and off-hand attacks to account when calculating the bonus it gives? Does it reduce the total number of attacks down to two even if I'm wearing two weapons? If so, will both attacks be done with the main hand, or how does it split the attacks? I'm considering to take this feat for a rogue with low AB, since to my understanding sneak attack only works on the first attack that hits anyway.

According to the All things Sembian Fencing! thread:

The number of lost attacks used to calculate your bonus is based purely on your BAB. So things like Greater Flurry or fighting with 2 weapons wont increase your bonus. So with a BAB of 12 that would be considered 3 attacks. So the feat would tally 1 lost attack which would gain you a +2 AB. But AB does not stack with items, so if you have a +2 weapon then your AB would not change.

Not sure why you are not getting a +2 tumble bonus though. So for most builds feats like Athkathlan or One Hander are probably better.

As for the sneak attack thing, it's all attacks in your first flurry. See Question about Sneak Attack flurries and BAB thread for more details.

First flurry is assuming you're attacking from stealth and using Hide in Plain Sight (HIPs) to re-engage. Otherwise, it's not worth worrying about. I think the general consensus is going to be that Sembian Fencing is not worthwhile for a sneak rogue with HIPs because generally most things have low AC when flat footed on BGTSCC to where you want to maximize your number of attacks in your first flurry for the most sneak dice possible in the round (rather than giving attacks in the flurry up for ab).

Thank you for the quick reply. It seems like I had misunderstood quite a lot.
