Sorcerer Rogier

Prowess, Reach

Whenever Sorcerer Rogier attacks, create a
glintblade artifact and equip it to Sorcerer Rogier.
When Sorcerer Rogier gets 4 or more glintblade artifacts equipped, he can sacrifice a minimum of 4 glintblades to do X damage to a target where X is
the number of glintblade artifacts sacrificed.

"The pleasure's mine. Rogier's the name. A sorcerer,
as you might have guessed."
