  • Plant Speech. trees
  • Plant Form. Small gympie-gympie tree. A creature that touches the tree must make a DC 19 Constitution saving throw or become poisoned.
  • Verdant Burst. When the leshy dies, a burst of primal energy explodes from its body, restoring 4d12 hit points to each plant creature in a 60- foot radius. Any non-plant creature in the radius makes a DC 19, Consaving throw or becomes poisoned. A poisoned creature can repeat the save at the end of their turn. The area fills with gympie-gympie trees, becoming difficult terrain. If the terrain is not viable for these trees, they wither and die after 24 hours.
  • Trichome Cloud. A cloud of broken trichomes surround the leshy. Any creature starting its turn within 30-foot feet of the leshy must succeed a DC 19 Con. saving throw or be poisoned and take 18 (4d8) poison damage. On a success, the target takes half as much damage and is not poisoned. A poisoned creature can repeat the saving throw at the end of their subsequent turns.


  • Multiattack. The Gympie-Gympie leshy makes three attacks with either their Wide Leaf or Nettled Berry attacks.
  • Wide Leaf. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 17 (2d10 + 6) slashing damage plus 18 (2d8) poison damage.
  • Nettled Berry. Ranged Weapon Attack: +10 to hit. Range 40/160 ft., one target. Hit: 17 (3d8+4) bludgeoning damage plus 13 (3d8) poison damage.


  • Wide Leaf. The leshy makes its Wide Leaf attack.
  • Stinger (Costs 2 Actions). The leshy flies towards a target with 60 feet to sting them. This movement does not trigger reactions. The creature makes a DC 20 Dex. saving throw, taking 18 (4d8) poison damage and 18 (4d8) piercing damage on a failure or half as much damage on a success.
  • Lingering toxin (Costs 3 Actions). All creatures within 30 feet of the leshy make a save with disadvantage against Trichome Cloud. If poisoned from this ability, the save cannot be repeated each turn.


The cocktail of toxins within the trichome of the Gympie-Gympie is not fully known. Whatever compounds contribute to this incredibly painful sting, they are stable and long-lasting, which contributes to the extreme duration of Gympie-Gympie stings.

Long dead and dry leaves of the tree are even able to deliver a similar dose as living material, making clean up of a fallen tree especially challenging.

One of the most toxic plants in the world, its nickname “Stinging Tree” undersells Gympie-Gympie’s extreme danger. Covered in needle-like hairs called trichomes, which function as hypodermic needles, the slightest touch can pierce skin, delivering powerful toxins that linger years after exposure.

It takes a skilled hand to create a leshy from such a dangerous plant, and one has to wonder about the strength and intentions of this leshy’s sculpture.

An unusually aggressive leshy, it is best to avoid, as even a successful encounter will leave the party suffering for months to come.
