The Artillerist is a military specialist who deals with the construction, transportation, and use of catapults. Both bolt throwers and stone throwers are covered by this career, but cannon and bombards are not. The Artillerist will be the captain of a catapult crew, directing the crewmen (who will be ordinary soldiers or militia) as they load and fire the machine. Artillerists can direct the operation of one catapult for each 10 points of their I score.
