Drawbridge

The drawbridge is the main single-hex pathway into a castle walls during siege combat. It can be destroyed by catapult fire, the Earthquake spell, and cyclops creatures, but it is more resilient than other sections of the wall. Creatures crossing the drawbridge do not suffer moat damage, and any slain creatures on the drawbridge will trap it in the open position. This is called "drawbridge trapping" and can often be utilized against computer opponents sending melee creatures into combat.
