Apologies if this has come up before, I did my best to check, but didn't turn anything up.
For reference: Focused Shot (Combat)
Prerequisites: Int 13, Point Blank Shot, Precise Shot
Benefit: As a standard action, you may make an attack with a bow or crossbow and add your Intelligence modifier on the damage roll. You must be within 30 feet of your target to deal this extra damage. Creatures immune to critical hits and sneak attacks are immune to this extra damage.
Deadly Range (Ex) (Sniper, alternate Rogue archetype)
At 3rd level, a sniper increases the range at which she can apply her sneak attack damage by 10 feet. This range increases by 10 feet for every 3 levels after 3rd.
Now, what prompts me to ask this (other than a heaping helping of self-interest, naturally) is this: The standard sneak attack range is 30', same as Focused Shot. Things that are immune to Sneak attacks are immune to focused shot. So, it leads me to wonder if they operate on similar principles. If you can hit the vitals well enough to sneak attack it, can hit them well enough to Focused Shot it? Or is it a flat 30', period, no exceptions?
Focused Shot came out well before the APG and the Sniper archetype were released, so couldn't have been specifically mentioned to be included or excluded. And if there's errata already released on the matter, I can't find it.
... My crossbow sniper curses/damns you appropriately, depending on your response. :P
