  • Ethereal Sight. The spriggan can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.
  • Incorporeal Movement. The spriggan can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.
  • Innate Spellcasting. The spriggan’s innate spellcasting ability is Wisdom (spell save DC 12). It can innately cast the following spells, requiring no material components:
  • Siege Monster. The spriggan deals double damage to objects and structures.
  • Undead Nature. A spriggan doesn’t require air, food, drink, or sleep.


  • War Pick. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) piercing damage, or 14 (2d8 + 5) piercing damage while enlarged plus 13 (3d8) necrotic damage.
  • Javelin. Melee or Ranged Weapon Attack: +8 to hit, reach 5 ft. or range 30/120 ft., one target. Hit: 8 (1d6 + 5) piercing damage, or 12 (2d6 + 5) piercing damage while enlarged plus 13 (3d8) necrotic damage.
  • Etherealness. The spriggan enters the Ethereal Plane from the Material Plane, or vice versa. It is visible on the Material Plane while it is in the Border Ethereal, and vice versa, yet it can’t affect or be affected by anything on the other plane.
  • Horrifying Visage. Each non-undead creature within 60 feet of the spriggan that can see it must succeed on a DC 12 Wisdom saving throw or be frightened for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, ending the frightened condition on itself on a success. If a target’s saving throw is successful or the effect ends for it, the target is immune to this spriggan’s Horrifying Visage for the next 24 hours.
  • Enlarge (Recharges after a Short or Long Rest). For 1 minute, the spriggan magically increases in size, along with anything it is wearing or carrying. While enlarged, the spriggan is Large, doubles its damage dice on Strength-based weapon attacks (included in the attacks), and makes Strength checks and Strength saving throws with advantage. If the spriggan lacks the room to become Large, it attains the maximum size possible in the space available.
  • Create Whirlwind. A 5-foot-radius, 30-foot-tall cylinder of swirling air magically forms on a point the spriggan can see within 120 feet of it. The whirlwind lasts as long as the spriggan maintains concentration (as if concentrating on a spell). Any creature but the spriggan that enters the whirlwind must succeed on a DC 16 Strength saving throw or be restrained by it. The spriggan can move the whirlwind up to 60 feet as an action, and creatures restrained by the whirlwind move with it. The whirlwind ends if the spriggan loses sight of it. A creature can use its action to free a creature restrained by the whirlwind, including itself, by succeeding on a DC 16 Strength check. If the check succeeds, the creature is no longer restrained and moves to the nearest space outside the whirlwind.


Standing around four feet tall, a spriggan’s body is hunched and misshapen, its proportions warped in unsettling ways. The creature’s limbs are disproportionately long and spindly, ending in clawed fingers that are capable of tearing through flesh and bone. Its eyes, small and beady, gleam with a malevolent intelligence, and its toothy mouth often twists into a wicked grin, revealing rows of sharp, jagged teeth.

Spriggans are notorious creatures that inhabit cromlechs, ancient forts, and remote countryside areas. They guard hidden treasures and are known to cause blights on crops, steal babies, and generally bring chaos and fear to their surroundings.

Spriggans enjoy causing mischief and harm to those who cross their paths. They can shapeshift at will, assuming the form of a grotesque human or a fearsome giant. In their giant form they use their size and abilities to terrorize and attack unsuspecting victims.

Spriggans are associated with ancient ruins and burial sites. They are believed to be ghosts of giants, retaining immense strength even in their smaller forms. Spriggans are often blamed for storms, crop failures, thefts, and other misfortunes.

They are known to be fond of hoarding treasures and causing havoc. Spriggans often serve as guardians for hidden caches of wealth and artifacts, and their presence is often a warning sign to travelers and adventurers that danger lies ahead.
