I'm making a level three character for a new campaign, and think I might have stumbled upon a way of getting 4d6 sneak attack damage at level three while dealing damage while grappling.
My character has two levels of Brawler with the "Strangler" arctype, and one level of rogue.
The class feature: Strangle (Ex)
At 1st level, a strangler deals +1d6 sneak attack damage whenever she
succeeds at a grapple check to damage or pin an opponent. The strangler is
always considered flanking her target for the purpose of using this ability.
This damage increases by +1d6 at 2nd, 8th and 15th levels.
Combined with the feat: Strangler (Combat)
Whenever you successfully maintain a grapple and choose to deal damage, you
can spend a swift action to deal your sneak attack damage to the creature
you are grappling.
Because the sneak attack damage from Strangle (Ex) automatically deals 2d6 damage at level two, and Strangler (Combat) allows me to spend a swift action to deal my sneak attack damage (which for now is 1d6 from one level in rogue), do these different sneak attack damages add up?
If I then use the feat: Accomplished Sneak Attacker
Your sneak attack damage increases by 1d6.
Your number of sneak attack dice cannot exceed half your character level
the sneak attack damage from the rogue is increased to 2d6. If I then grapple and choose to deal damage, would I deal my unarmed strike damage (1d6), plus 2d6 sneak attack from Strangle (Ex) and 2d6 from spending a swift action, adding up to 1d6 + 4d6 sneak attack damage?
