Called Shot is an ability first learned by level 4 archers in Baldur's Gate II. The archer is a ranger kit in the game. As the class advances the ability becomes more and more powerful.
At level four, the Called Shot reduces the target's THAC0 by one point, making it more difficult for it to hit your party members. At level eight the ability also inflicts a one point penalty to the target's saving throw vs. magic. At level twelve the target loses one point of strength, and at level sixteen two points of missile damage are incurred. These effects are cumulative, and due to the experience cap in the game the archer cannot become stronger than level seventeen. Although they can max out at level thirty-four in the expansion pack Called Shot does not gain any new bonuses.
