The design team and the developers have talked about this ability, and we agree that it is problematic, in that it isn't clear, and (depending on how it's interpreted) is either a very poor ability or a very powerful ability.
Problems include:
* text isn't clear whether you can shoot one target multiple times
* two rolls needed to resolve the effect (ranged touch attack and saving throw)
* damage is low if you can't shoot a particular target more than once, but high if you can
* ability starts with 6 shots when you first gain it, but caps out at 10 shots only 4 levels later
There's no easy or obvious fix for the ability as written.
Rather than quickly putting together an official FAQ or errata with a fix, having people find problems with it, and post revisions to that fix, what we're going to do is present a rough idea of what we think the ability should do, let people pick at it for a while, and revise the wording based on this feedback.
Here is the proposed new wording, parsed over several lines for easier reading:
Weird Words (Su): At 6th level, a sound striker can start a performance as a standard action, lashing out with up to 1 potent sound per bard level (maximum 10), each sound affecting one target within 30 feet. Note: "Up to" means you can choose to fire fewer than the maximum number.
No target can be struck more than once. Note: This makes the intent clear.
Each potent sound expends 1 round of bardic performance. Note: This is new, and keeps the cost from being trivial at higher levels for using the maximum number of sounds.
These are ranged touch attacks.
Each weird word deals 1d8 points of damage plus the bard's Charisma bonus. At 10th, 14th, and 18th level, the damage increases by 1d8. Note: Scaling damage is new. Fort saving throw removed.
The bard chooses what type of damage each word deals (bludgeoning, piercing, or slashing).
This performance replaces suggestion.
I'm OK with this but there are additional clarifications needed. My PFS group has several players who play this and the following are continually contested during games.
Can we clarify whether these are weapons and affected by things like point blank shot, cluster shot, etc?
Also can we clarify if these are magical?
Other than that, can please allow a free rebuild in PFS for those who have this build. This was a go-to build for players looking for a high DPR build for bard and this change (specifically not being able to target one target) makes this build less effective than other options.
Outside of that, this looks good for what it is intended to do.
