Ascaros, a Nidalese shadowcaster.

A shadowcaster is a Kuthite spellcaster—often, though not always, a wizard—who melds the Midnight Lord's divine shadow magic with the arcane arts. A shadowcaster's spellcasting is also known as shadowcasting.1

On Golarion

Shadowcasting is widely practiced in Nidal, though cabals of shadowcasters exist in Galt and Taldor.1 Nidal loans shadowcasters to Cheliax in a number of roles, including service in Westcrown's Midnight Guard.2


Many shadowcasters are trained by the shadowcallers at the Dusk Hall in Pangolais.3
