  • Arcane Blood. When determining hit points, the dragon uses its Intelligence modifier rather than its Constitution modifier. Additionally, the dragon may use its Intelligence modifier for weapon attack and weapon damage rolls (included in the attack).
  • Legendary Resistance (3/Day). When the dragon fails a saving throw, it can choose to succeed instead.
  • Superior Magic Resistance. The dragon has advantage on saving throws against spells and other magical effects. When the dragon succeeds on a saving throw against a spell or magical effect and suffers an effect on a success, it instead suffers no effect.


  • Multiattack. The dragon makes three attacks: one with its Bite and two with its Claw. The dragon can forgo making a Bite attack in this manner to instead use its Lock Magic or Silence action.
  • Bite. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 34 (5d10 + 7) piercing damage.
  • Claw. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 16 (2d8 + 7) slashing damage.
  • Force Breath (Recharge 5–6). The dragon exhales kinetic force in a 60-foot cone. Each creature in the area must attempt a DC 24 Dexterity saving throw, taking 77 (14d10) force damage on a failed save, or half as much damage on a successful one. Creatures that fail their saving throw are knocked prone and pushed to the end of the affected area.
  • Lock Magic. The dragon suppresses the magic of a magic item it can see of very rare rarity or lower for 1 hour. For the duration, the affected item cannot produce any effects or gain the benefit of any magical properties.
  • Silence. The dragon magically silences a creature it can see within 120 feet of it. The target must succeed on a DC 24 Wisdom saving throw or be unable to speak for 1 minute. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.


  • Magic Eater. When the dragon succeeds on a saving throw against a spell, the dragon can use its reaction to devour the lingering magic. When it does so, it magically regains 28 (8d6) hit points.


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.

  • Claw. The dragon makes a Claw attack.
  • Arcane Power (Costs 2 Actions). The dragon uses its Lock Magic or Silence action.
  • Breath Weapon (Costs 3 Actions). The dragon uses or recharges its Force Breath action.


The sigil dragon is an eternal wanderer until its old age begins to get in the way of its travels. Each one traverses sea, land, and the planes themselves seeking knowledge, arcane prowess, and magic items. Many are known to trade, bargain, or kill to achieve their goals—whatever is easiest in any given scenario. Because they travel most of their lives, they don’t establish lairs. To make up for this lack, each sigil dragon has access to an extradimensional space attuned to its sigil from which it can stow or pull various items and tools, be it gold and trinkets for trade or powerful arcane instruments.

Most notably, sigil dragons are known to covet spellbooks, keeping a vast supply of paper and ink among their belongings, eager to record spells from those they encounter on their travels. Many universities highly prize and desire a business relationship with a sigil dragon, for each one carries with it a steady supply of items and tools fit for scholarly pursuits and cherishes the unique nature of the scrolls they can create.

The strangest of the wondrous dragons presented here, sigil dragons are often referred to as merchant drakes or fortress dragons due to the scales on their head and neck. These scales form a covering that makes it appear as though the dragon is wearing a helmet, masking all expression. Their scales are light blue with patchy black skin underneath, making the dragon appear to be wearing scale mail. Its talons are scythed, its wingtips are sharpened, and it has no horns adorning its head. For much of their life, sigil dragons are no larger than hippogriffs.

As they age, magic suffuses their bodies and grants them magnificent size and prowess, and their scales give off an opalescent sheen. Their most prominent visible trait is a draconic letter floating in the air just in front of their foreheads.
