I think I can see the misunderstanding on that one.

When stoneskin completely negates damage, it does also negate certain 'side effects', believe it or not. The one that comes to mind is Ifrit HM's "fire burst knocking everything away" - if you absorb the whole thing via Stoneskin, you won't be knocked back.

However, I can say with almost complete certainty that Stoneskin does not block the scale cloud (because it does no damage), and doesn't mess with the enmity mechanics specific to that fight. If I'm wrong on that, it might be the one time you genuinely don't want to Stoneskin - but again, almost completely sure it doesn't.
