Bog Hag

Plant Camouflage. The Bog Hag has advantage on Dexterity (stealth) checks it makes in any terrain with ample obscuring plant life..

Tree Stride. Once on each of its turns, the Bog Hag can use 10 feet of its movement to step magically into one living tree within 5 feet of it and emerge from a second living tree within 60 feet of it that it can see, appearing in an unoccupied space within 5 feet of the second tree. Both trees must be Large or bigger.

Innate Spellcasting. The hag's innate spellcasting ability is Charisma (spell save DC 13, +5 to hit with spell attacks). She can innately cast the following spells, requiring no material components:

At Will: infestation, ice knife, primal savagery

2/day each: hold person, wither and bloom

1/day each: call lightning, spike growth

Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage.

Illusory Appearance. The hag covers herself and anything she is wearing or carrying with a magical illusion that makes her look like an ugly creature of her general size and humanoid shape. The effect ends if the hag takes a bonus action to end it or if she dies.

The changes wrought by this effect fail to hold up to physical inspection. For example, the hag could appear to have no claws, but someone touching her hand might feel the claws. Otherwise, a creature must take an action to visually inspect the illusion and succeed on a DC 16 Intelligence (Investigation) check to discern that the hag is disguised.
