But you can't use arrows *and* sneak attack together, can you? I used them when I had no sneak attack option or the thunder things to try and knock someone off, but that doesn't come close to the damage my other characters could dish out in the same turn. Hmpf.
I definitely have seen sneak attack fire with special arrows (using the “reaction” trigger for sneak attacking, as it’s true it can’t be actively selected). Not that I use them often, as my multi-class sorceror/rogue is usually casting spells with her actions.
