Maester

{w}{w}{x}: You gain {x} life.
{b}{b}{x}: Maester deals {x} damage to target
creature.
There is no limit to what you might learn ... I can
teach you history, healing, herblore. I can teach you
the speech of ravens, and how to build a castle, and
the way a sailor steers his ship by the stars. I can
teach you to measure the days and marks the
seasons, and at the Citadel in Oldtown they
can teach you a thousand things more.
