Enemies of Castle Defenders spawns in the dungeons. They spawn on top of their blocks, then attack you if you are in range. There are three kinds of enemies. Knights fight with a sword, and once spawned they walk around the area. Archers stay on their block, and throw arrows. Mages fights with fireballs and don’t walk either.
