So my party is headed for Armag's Tomb next. The Black Sisters have Shout prepared. My PCs are using a lot of Ioun Stones... The sisters hate the PCs, and are super vindictive, but is it maybe a little TOO far to try and break all their Ioun Stones?
If I read the spell correctly, the PCs would get a Reflex save to keep their stones safe against the spell's damage. Depending on their saves, that may or may not be feasible.
If you want to tone it down, maybe give them a separate save for every ioun stone.
