Bone and Ghost Dragons are level 7 creatures of Necropolis town. They are recruited from the Dragon Vault.

Bone and Ghost Dragons are raised from dragon corpses. Both of these creatures have a ferocious biting attack and lower the morale of enemy units by one when they appear on the battlefield. Ghost dragon attacks have a 20% chance of aging their targets. Aged troops have the hit points of all their members halved. Placing Hydras or any living Dragons in the Skeleton Transformer will give you Bone Dragons instead of regular Skeletons. Bone and Ghost Dragons, however, being undead (and therefore non-living), get turned into Skeletons.

Bone Dragons are the only type of dragon that doesn't require any magical resources to recruit.

Aging special ability

Ghost Dragons have aging special ability, which has 20% probability to occur after they have attacked target creature stack and before the stack has a chance to retaliate. It causes maximum health of every creature in the target stack to be halved. The effect lasts for 3 combat rounds, and can only be removed with the Cure or Dispel spell. Additionally, non-living creatures are immune to aging.

When Ghost Dragons successfully ages a stack, any health lost before the aging takes effect remains lost. However, the aging cannot kill the unit, but it will have 1 health left. For example, a Ghost Dragon attacks one Angel and deals 60 points melee damage before the aging occurs. The Angel will have 40 points health left, which is the result of calculation

200÷2-60 = 40

If the damage of the Ghost Dragon would have been 130, the Angel would have had 1 health left, which would have been the result of calculation

200÷2-130 = -30 → 1

The effect of aging has a multiplicative effect with Wyvern Monarchs' poisonous ability. This means, that the creature stack's health could potentially be quartered.
