Breath Weapons (Recharge 5-6). The dragon uses one of the following breath weapons.

Expiration. The dragon releases a wave of death in a 30-foot line that is 5 feet wide. Each creature in that line must make a DC 14 Dexterity saving throw. On a failed save, a creature takes 49 (11d8) necrotic damage and is frightened until the end of its next turn. On a successful save, a creature takes half as much damage and is not frightened. A humanoid reduced to 0 hit points by this damage dies and rises as a zombie under the dragon's control. The zombie acts immediately after the dragon in the initiative count.

Weakening Breath. The dragon exhales gas in a 30-foot cone. Each creature in that area must succeed on a DC 17 Strength saving throw or have disadvantage on Strength-based attack rolls, Strength checks, and Strength saving throws for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
