Empowered Raymond

Empower Spell (page 122): If I use Empower Spell on a spell that has a die roll with a numerical bonus (such as cure moderate wounds), does the feat affect the numerical bonus?

Yes. For example, if you empower cure moderate wounds, the +50% from the feat applies to the 2d8 and to the level-based bonus.

Apparently the bonus from a per-level effect counts as a variable for Empower Spell.  Aside from the Cure spells, Ray of Enfeeblement springs to mind.
