Druid Groove

You invoke the spirits of joyful nature to protect an area outdoors or underground. The area can be as small as a 30—foot cube or as large as a 90-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 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 Rock. You can fill any number of 5-foot squares on the ground with thick grunge sound, making the are difficult to pass through due to Nevermind by Nirvana blasting at maximum volume. The grunge music reaches 10 feet high. In addition, every foot of movement through the music costs 2 extra feet. To a creature with a hearing disability the music obscures nothing and looks like soft a normal area, with notes floating in the air.

Undergrowth of the 90‘s disco. You can fill any number of 5-foot squares on the ground that aren’t filled with fog with a funky coloured danceboard. Every creature moving through the area must succeed on a dc18 Wisdom saving throw or start breakdancing on the spot. (no matter which creature) They are in prone condition until attacked, the effect stops after the 24 hours or when the caster decides to stop the spell

Groove Guardians. You can animate up to four trees in the area, causing them to uproot themselves from the ground and dance agressively. These trees have the same statistics as an awakened tree, which appears in the Monster Manual, 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 approach them agressively and bodyslam them into dancing with them or  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.
