Like a lot a Magus, I picked Magical Lineage on Shocking Grasp. Like a lot of Magus, I use this with Intensified Spell. So I am the owner of a Pearl of Power (1st). Can I use it to recall the Intensified Shocking Grasp? AFAIK, it should work. Did I understand well?
From metamagic feats errata:
For example, an empowered burning hands uses a 3rd-level spell slot, counts as a 3rd-level spell for making concentration checks, counts as a 3rd-level spell for a magus’s spell recall or a pearl of power.
