Well, burn them if you have an army of undead skeletons at your disposal. If so, you can always rebuild those bridges later if it turns out you need them after all. Dubbadgrim has created a terrifyingly “humerus” siege scene for the Colossal Castle Contest complete with a swampy, stagnant moat, fire ballista, and of course, a whimsical skeleton bridge. Those defenders don’t stand a chance!
