Traits
Shapechanger. The Leshy can use its action to polymorph into a Medium or Small humanoid, or into a beast or plant of CR 3 or lower, or back into its true form. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.
Innate Spellcasting. The Leshy's innate spellcasting ability is Wisdom (spell save DC 18, +10 to hit with spell attacks). It can innately cast the following spells, requiring no material components:
At Will: Druidcraft (PHB, p.236), Pass Without Trace (PHB, p.264), Speak With Animals (PHB, p.277), Speak With Plants (PHB, p.277), Fog Cloud (PHB, p.243), Entangle (PHB, p.238), Invisibility (self only) (PHB, p.254)

Magic Resistance. The Leshy has advantage on saving throws against spells and other magical effects.
Master of Beasts. Beasts within 1 mile of the Leshy's forest are charmed by it and are friendly to the Leshy and its companions.
Variable Size. The Leshy can use a bonus action to magically change its size between Tiny and Huge. Its statistics remain the same, but its equipment grows or shrinks with it. While Huge, its reach increases by 10 feet.
Forest Camouflage. The Leshy has advantage on Dexterity (Stealth) checks made to hide in forested terrain.
Magic Weapons. The Leshy's weapon attacks are magical.
Actions
Multiattack. The Leshy makes two attacks with its Quarterstaff or two Slam attacks.
Quarterstaff (Staff Form). Melee Weapon Attack: +9 to hit, reach 5 ft., one target.
Hit: 9 (1d8 + 5) bludgeoning damage, or 10 (1d10 + 5) bludgeoning damage if used with two hands.
Slam (Tree Form). Melee Weapon Attack: +9 to hit, reach 10 ft., one target.
Hit: 14 (2d8 + 5) bludgeoning damage.
Vanishing Woodlands. The Leshy conjures magical mist and foliage in a 60-foot radius centered on itself. The area becomes heavily obscured for creatures other than the Leshy. The effect lasts for 10 minutes or until the Leshy dismisses it (no action required).
Guiding Misdirection. The Leshy targets one creature it can see within 60 feet. The target must succeed on a DC 18 Wisdom saving throw or become lost. While lost, the creature can't regain its bearings and automatically fails any ability check to navigate or find its way. This effect lasts until the creature leaves the forest, the Leshy is destroyed, or a remove curse spell is cast on the creature.
Reactions
Confounding Presence. When a creature the Leshy can see within 30 feet makes an attack roll against it, the Leshy imposes disadvantage on the roll.
Legendary Actions
The Leshy can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time, and only at the end of another creature's turn. The Leshy regains spent legendary actions at the start of its turn.
Move. The Leshy moves up to its speed without provoking opportunity attacks.
Whispering Wind. The Leshy casts druidcraft or message.
Summon Beast (Costs 2 Actions). The Leshy summons one beast of CR 2 or lower to aid it. The beast appears in an unoccupied space within 30 feet and acts on the Leshy's turn. It obeys the Leshy's commands and disappears after 1 hour or when it drops to 0 hit points.
Lore
A woodland spirit and lord of animals.
Leshy is the chief spirit of the forest. He has a human appearance with distinctive features: green eyes and long hair, sometimes falling below his shoulders. He is described in various ways, but generally, he may have thick eyebrows and a long green beard. Interestingly, this spirit has blue blood.
He is often depicted wearing his shoes on the wrong feet: the right shoe is on his left foot, and the left shoe on his right.
