Traits

Legendary Resistance (3/Day). If the dragon fails a saving throw, it can choose to succeed instead.

Actions

Multiattack. The dragon makes three attacks: one with its bite and two with its claws. Or three with its rapier while in humanoid form.

Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 7) piercing damage plus 5 (1d10) lightning damage.

Claw. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage.

Tail. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 16 (2d8 + 7) bludgeoning damage.

Rapier (Humanoid form only). Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 11 (1d8 + 7) piercing damage.

Lightning Breath (Recharge 5–6). The dragon exhales lightning in a 90-­foot line that is 5 feet wide. Each creature in that line must make a DC 19 Dexterity saving throw, taking 66 (12d10) lightning damage on a failed save, or half as much damage on a successful one.

Bonus Actions

Human Form. The dragon magically transforms into any humanoid that is Medium or Small (usually a human or elf noble), while retaining its game statistics (other than it’s size). This transformation ends if the dragon is reduced to 0 hit points or uses a bonus action to end it.

Reactions

Parry (Humanoid Form Only). The dragon adds 2 to its AC against one melee attack that would hit it. To do so, the dragon must see the attacker and be wielding a melee weapon.

Legendary Actions

The dragon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The dragon regains spent legendary actions at the start of its turn.

Detect. The dragon makes a Wisdom (Perception) check.

Tail Attack. The dragon makes a tail attack.

Rapier (Humanoid Form Only). The dragon makes a rapier attack.

Lair and Lair Actions

 Unlike most blue dragons who live in secluded deserts, blue dragon nobles live in cities, hiding in plane site disguised as elvish or human nobility.

Lair Actions

On initiative count 20 (losing initiative ties), the dragon takes a lair action to cause one of the following effects; the dragon can’t use the same effect two rounds in a row:

  • Part of the ceiling collapses above one creature that the dragon can see within 120 feet of it. The creature must succeed on a DC 15 Dexterity saving throw or take 10 (3d6) bludgeoning damage and be knocked prone and buried. The buried target is restrained and unable to breathe or stand up. A creature can take an action to make a DC 10 Strength check, ending the buried state on a success.
  • A cloud of sand swirls about in a 20-foot-radius sphere centered on a point the dragon can see within 120 feet of it. The cloud spreads around corners. Each creature in the cloud must succeed on a DC 15 Constitution saving throw or be blinded 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.
  • Lightning arcs, forming a 5-foot-wide line between two of the lair’s solid surfaces that the dragon can see. They must be within 120 feet of the dragon and 120 feet of each other. Each creature in that line must succeed on a DC 15 Dexterity saving throw or take 10 (3d6) lightning damage.

Regional Effects

The region containing a legendary blue dragon noble’s lair is warped by the dragon’s magic, which creates one or more of the following effects:

  • Once per day, the dragon can alter the weather in a 6-mile radius centered on its lair. The dragon doesn’t need to be outdoors; otherwise the effect is identical to the control weather spell.
  • Humanoids, Beasts, and Monstrosities that are born within 6 miles of the lair have a high likelihood of being half-dragons.
  • Creatures that spend a year within 1 mile of the dragon’s lair find blue objects fascinating and feel compelled to acquire them at every opportunity.

If the dragon dies, changed weather reverts to normal, as described in the spell, and the other effects fade in 1d10 days.
