Der Meisterbogenschuetze (German for "The Master Bowman") is a trophy/achievement in the Zombies mode DLC map Der Eisendrache that appears in Call of Duty: Black Ops III.
It requires the player to obtain all of the ancient bows, which can only be done by upgrading all 4 Wrath of the Ancients quest.
It should be noted that this achievement/trophy can be unlocked solo or on co-op; the bows can all be upgraded in a solo game with much difficulty, but if four players all have the respective bows upgraded, the achievement will unlock for everyone in the game.
