Notes
The standard scroll for this spell cannot be used by clerics (but can be used by bards (even though bards cannot cast this spell). This has the consequence that clerics have been blocked from using this spell in conjunction with scribe scroll (since otherwise they would obtain a scroll they cannot use).
