Description: Not a bug per sé. Though the DC of the force wave isn't on par with for example the Fey Horn, which is lower on the crafting skill but with a higher DC of 20 and a more useful effect.
The DC is 15.. which if failed would get one about 22 sonic damage. I managed 11 damage on a succesful save. I suggest either raising the DC or upping the damage dice slightly.
Verified: As far as the dc is concerned, yes.
Reproducable: As far as the dc is concerned, yes.
