V from the Trees

Multiattack: V uses any combination of 2 Staff or Radiant Bolt attacks. He can replace one of these attacks with a spell from his Spellcasting feature.

Staff. Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) Force damage plus 18 (4d8) thunder damage.

Radiant Bolt. Ranged Spell Attack: +14 to hit, range 120 ft., one target. Hit: 28 (6d6 + 7) radiant damage, and the next attack roll against the target has advantage.

Spellcasting. The archdruid casts one of the following spells, using Wisdom as the spellcasting ability (spell save DC 22):

At will: cure wounds, entangle, speak with animals, wither and bloom

3/day each: animal messenger, dominate beast, faerie fire, tree stride, polymorph, 

1/day each: commune with nature (as an action), mass cure wounds, greater restoration, transport via plants, animal shapes, earthquake, shapechange

Change Shape (4/Day). The archdruid magically transforms into a creature listed below, or any Beast or an Elemental with a challenge rating of 9 or less. He can remain in that form for up to 9 hours. V can choose whether its equipment falls to the ground, melds with its new form, or is worn by the new form. V reverts to his true form if he dies or falls unconscious. V can revert to his true form using a bonus action. If his new form has hands, he prefers to keep the staff and use it if needed.

While in a new form, V's stat block is replaced by the stat block of that form, except he keeps his current hit points, his hit point maximum, this bonus action, his languages and ability to speak, and his Spellcasting and Staff actions.

Additionally, when using this bonus action, V gains 50 Temporary HP.

The new form’s attacks count as magical for the purpose of overcoming resistances and immunity to nonmagical attacks.

Elemental Defense: Trigger: V takes Acid, Cold, Fire, Lightning, or Thunder damage. Response: V gains resistance to one of those damage types that he chooses. This resistance is lost at the start of his next turn.
