Limited to Dragonborns, Dragons and certain Magic Pact users. Upon killing an enemy and reducing their hit points to zero, you can use this spell as a bonus reaction to reanimate that enemy as a Dragon of your race type or Draconic Bloodline. The Dragon naturally has XD10 (x = your character level) hit points, an Armor Class of 20, 17 Strength, 15 Dexterity, 15 Constitution, 8 Intelligence, 16 Wisdom, 10 Charisma. The Dragon can only use a basic Slash (Hit +5, Damage 3D6 Slashing Damage). The Dragon has a 60ft walking speed, and a flying speed of 2300ft. The Dragon can carry up to 750lbs, including small constructs and people. The Dragon loses 20ft of walking speed and 1000ft flying speed when carrying over 600lbs, and loses 45ft walking speed and cannot fly while carrying over 750lbs. The Dragon cannot move when carrying over 1000lbs. The Dragon dissapears after an hour, or if it loses all of its hit points, or if the caster releases the spell.
