Swamp Dryad

The dryad has advantage on saving throws against supernatural effects.

The dryad can communicate with Beasts and Plants as if they shared a language.

The dryad can use 10 feet of movement to step into one living tree within their reach and emerge from a second living tree within 60 feet of the first tree, appearing in an unoccupied space within 5 feet of the second tree. Both trees must be Large or larger.

The dryad makes two Slam attacks and uses Entangling Roots, if available.

Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) piercing damage, and the target must make a DC 18 Constitution saving throw. On a failed save, the target takes 14 (4d6) poison damage and is poisoned for 1 minute. On a successful save, the target takes half as much damage and isn't poisoned.

The dryad chooses a point they can see within 60 feet of them, causing tree roots to pull free of the ground and attack in a 15-foot radius centered on that point. If the dryad is within 5 feet of their tree, the radius of this effect doubles to 30 feet. Each creature in that area must succeed on a DC 18 Strength saving throw or take 22 (4d10) bludgeoning damage and be grappled (escape DC 14).

While grappled in this way, a creature is restrained and their flesh begins to harden and turn to wood.

At the end of a creature's third consecutive turn being grappled in this way, they become petrified and turn into a hardwood statue. The petrified condition ends for that creature if the dryad uses an action to end it, or if the dryad dies.

The dryad targets up to five creatures they can see within 30 feet of them. Each target who can see the dryad must succeed on a DC 18 Wisdom saving throw or be frightened of the dryad (save ends at end of turn). If a target succeeds on their saving throw or the effect ends for them, the target is immune to the swamp dryad's Fey Intimidation for the next 24 hours.

The dryad touches a creature, who regains 18 (3d8 + 5) hit points. Alternatively, the creature removes one disease or neutralizes one poison afflicting them.
