Large TargetURL Copied!
Large Targets are models that are especially tall, such as Dragons, Giants and Greater Daemons. Such foes cannot easily take cover behind obstacles that would shelter lesser troops. Large Targets cannot claim cover modifiers for obstacles (see thechapter).
However, if youror is a Large Target (or is mounted on one), then the range of their respective and abilities is increased from 12" to 18" to represent the ease with which your troops can see them.
