Draconian Mark

You magically mark one creature you can see within range as your quarry. Until the spell ends, you deal an extra 3d6 damage to the target whenever you hit it with an attack roll. This damage is Acid, Cold, Fire, Lightning, or Poison (your choice when you make the attack).You also sprout a set of wings that gives you a Fly Speed of 60 feet and can hover, you critically score against the marked creature on a roll of 19-20, and the marked creature has disadvantage to attack you.

If the target drops to 0 Hit Points before this spell ends, you can take a Bonus Action to move the mark to a new creature you can see within range. This spell is always treated as Hunter's Mark for features that require casting that spell.
