Expertise and More Expertise Phasorq

Your two heads hardly ever agree on what to wear, where to go, nor what skills to learn. You've certainly found your main specialty by now, but that doesn't mean your other head has given up dabbling in something else entirely. During your daily preparations, you can focus your dabbling on a particular subject to become trained in one Lore skill of your choice. This proficiency lasts until your next daily preparations. Since this proficiency is temporary, you can't use it as a prerequisite for a skill increase or a permanent character option like a feat.
