There's a new artifact you can now obtain for the Templar / Carnifex class and its mirrors from classlead report #3695.

Artifact: multitalent (400cr)

Syntax: MASTERY ARTIFACT <talent>

Will let the owner select a second talent as part of the Mastery skill. Your second talent cannot share a weapon class with your first talent choice. The cooldown to repick still applies.

Penned by my hand on Tisday, the 4th of Slyphian, in the year 13 AC.
