For reference:
Ricochet Shot Deed (Grit)
You can ricochet a firearm shot off the wall and still hit your target.
Prerequisites: Grit class feature or Amateur Gunslinger feat, Blind-Fight.
Benefit: You can fire a shot at a wall or piece of solid terrain, and have it ricochet off. When you do, use the square immediately in front of the wall or piece of solid terrain to determine line of sight to a target, and this square is considered the new origin square of the attack. Use that square to determine the effects of cover, and your own square to determine the effects of concealment. You can make this shot as long as you have at least 1 grit point. When making this shot, you can spend 1 grit point to ignore the effects of all cover or concealment. You must choose to spend the grit point before you make the attack roll.
Highlighting mine.
Ok, so I've seen this come up in just a few threads from a while back and none of them really seem to answer my questions.
#1 Can I really shoot at a section of wall with my musket 200ft away, bounce the bullet off it, and hit another target 40 ft further on and have it count as my first range increment (since the space by the wall is now counted as the origin of my shot)?
#2 Same as #1, but now the target is invisible (Total Concealment) and ducking down peering at me from behind a rock (Improved Cover) from 240 ft away. So I spend a Grit point and do the same thing. No penalties involved. If I can roll his Touch AC, then I hit.
???
This seems a bit overpowered, doesn't it? Or am I just reading it wrong? I can't think the average GM would go for #1 at all and would instead count the entire trip of the bullet as the range. For #2, same issue with distance. But spending Grit to remove Cover/Concealment penalties, no problem there.
I think the origin part is only to say what the origin square is for determining line of sight and cover. Not for determining if the shot is in the first range increment.
So...
#1) No
#2) The only real question here is does the spending of Grit negate Invisibility? Invisibility technically provides total concealment, but you still can't visually locate the creature. So you would have to know which square the creature was in. But that aside it would ony be a touch attack if it were within the 1st range increment of your weapon, as determined from where you stand.
This isn't really clarified very well, but I don't think they intended for you to determine the range increment based on the new "origin" square.
I would agree with you that appears to be RAI. The sentence could have been better written, but the intent would seem to include the entire distance the bullet travels. Otherwise it's a bit overpowered.
For #2, the assumption is that you know which square the target is in. Another example might be a Ninja running up, sneak attacking the tank, and then swift vanishing. As you know he could not have moved from that space when your turn comes up, it would be a matter of spending the Grit to bounce a bullet off the wall, floor, or ceiling to get at the Ninja without suffering a miss chance....which makes sense considering Blind-Fight is a prereq for Ricochet anyway. So you are basically spending a Grit to reduce the miss chance from an average 25% to 0%. If you somehow target the wrong square, then the miss chance remains 100% as it does in any other case.
Edit: Looks like I need to amend the above as Blind-Fight doesn't offer any benefit when fighting ranged. Only melee. So it's a useless Feat tax that only comes into play when you suffer a melee attack from an invisible attacker or if you spend the Grit to remove the concealment penalty with Ricochet.
