Druidic Grove

Invoking the spirits of nature, you bid them to protect an area outdoors or underground. The area can be as small as a 30-foot cube or as large as a 120-foot cube. Buildings and other structures are excluded from the affected area. If you cast this spell in the same area every day for a year, the spell lasts until dispelled. The spell creates the following effects within the area. When you cast this spell, you can specify creatures as friends who are immune to the effects. You can also specify a password that, when spoken aloud, makes the speaker immune to these effects. The entire warded area radiates magic. A Dispel Magic spell cast on the area, if successful, removes only one of the following effects, not the entire area. That spell’s caster chooses which effect to end. Only when all its effects are gone is this spell dispelled.

Solid Fog. You can fill any number of 5-foot squares on the ground with thick fog, making them heavily obscured. The fog reaches 10 feet high. In addition, the fog makes the area Difficult Terrain. To a creatures immune to this effect, the fog obscures nothing and looks like soft mist, with motes of green and blue light floating in the air.

Grasping Undergrowth. You can fill any number of 5-foot squares on the ground that aren’t filled with fog with grasping weeds and vines, as if they were affected by an Entangle spell. To a creature immune to this effect, the weeds and vines feel soft and reshape themselves to serve as temporary seats or beds.

Spiked Growth. You can full any number of 5-foot squares on the ground that isn't filled with grasping undergrowth with twists and sprouts hard spikes and thorns as if under the effects of the Spike Growth. The areas of spiky growth are completely harmless towards creatures immune to this effect 

Grove Guardians. You can animate up to twelve trees in the area, causing them to uproot themselves from the ground. These trees have the same statistics as an Awakened Tree; except they can’t speak and their bark is covered with druidic symbols. If any creature not immune to this effect enters the warded area, the grove guardians fight until they have driven off or slain the intruders. The grove guardians also obey your spoken commands (no action required by you) that you issue while in the area. If you don't give them commands and no intruders are present, the grove guardians do nothing. The grove guardians can‘t leave the warded area. When the spell ends, the magic animating them disappears, and the trees take root again if possible.

Beings of the Grove. Several fey are summoned to the grove as if through the Conjure Animals and Conjure Woodland Beings. These fey-beasts are friendly to you and creatures you designate as friends immune to the harmful effects. These fey fight against creatures that intrude upon the grove and obey your spoken commands (no action required by you) that you issue while in the area. If you don't give them commands and no intruders are present, the fey do nothing. When the spell ends, or their hit points drops to 0, the creatures disappear.

Vine Walls. Around the perimeter of the area you choose to summon the grove. These walls are under the same effects as the Wall of Thorns. To a creature immune to this effect, the thorns retract and the wall automatically parts to make way for the creature.

Tree Movement. As long as there are trees within the area of the spell, you can move between them as if casting the Tree Stride. Creatures you designate as friendly upon casting this spell can move around the drove using the same method.

Casting this spell on the same spot once every 7 days for a year makes the grove permanent and the effects can no longer be dispelled through the use of a Dispel Magic.
