7th level (2 slots): fire storm, reverse gravity, regenerate

8th level (1 slots): animal shapes, feeblemind

Multiattack. The Zenithdruid can cast 1 spell and make 2 attacks

Quarterstaff. Melee Weapon Attack: +8 to hit (+8 to hit with shillelagh), reach 5 ft., one target. Hit: 5 (1d6 + 7 ) bludgeoning damage, 6 (1d8 + 2) bludgeoning damage if wielded with two hands, or 11 (1d8 + 7) bludgeoning damage with shillelagh.

Change Shape (2/Day). The Zenithdruid magically polymorphs into a beast or elemental with a challenge rating of 12 or less, and can remain in this form for up to 12 hours. The zenithdruid can choose whether its equipment falls to the ground, melds with its new form, or is worn by the new form. The zenithdruid reverts to its true form if it dies or falls unconscious. The zenithdruid can revert to its true form using a bonus action on its turn.

While in a new form, the Zenithdruid retains its game statistics and ability to speak, but its AC, movement modes, Strength, and Dexterity, if they are higher, are replaced by those of the new form, and it gains any special senses, proficiencies, traits, actions, and reactions (except class features, legendary actions, and lair actions) that the new form has but that it lacks. It can cast its spells with verbal or somatic components in its new form. The zenithdruid gains 100 temporary hit points.

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

The archdruid can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The archdruid regains spent legendary actions at the start of his turn.

Attack. The archdruid may make an attack.

Cast Spell. The archdruid casts a spell of 3rd level or lower.
