Bishop is the 3rd attainable rank if the Grendel wants to be upgraded, if not it is Rook.
Total Assault 3 - In the game, Bishops are tall, wear blue armor, and attack you with nothing but their long elastic-like arms. Only 3 Bishops are encountered: 1 in The Drop and 2 in The Zodiac just before you get to the final room.
- Lance-1055-Mentioned in the Novel of TA 3, Lance was the Bishop that Ivy fights in The Drop before she fights the Rose. Although this is never known in the game.
