Dragon Barrier

Summary
Size 1x1

The Dragon Barrier creates a shield that will absorb damage from Dragons and protect nearby buildings.
 * The Barrier created can absorb good amounts of damage. All buildings within the barrier receive no damage until the barrier is destroyed (even those on the edge of the Barrier's range). Once the barrier receives more damage than it can take, it is destroyed.
 * When two or more Dragon Barriers are protecting the same building, the damage that building receives is shared between all barriers.
 * The Barrier does not affect ground units.
