W.O.D.

The Wall of Dirigibles is the Boss of Easy Difficulty. It is the only boss that doesn't attack. It is a large number of M.O.A.B.s in a tight formation, so it is like a wall of M.O.A.B.s. It appears on level 55.

Trivia
The battle sequence music is an extended cut of Machinimasound's "The Land of the Wizard".
