Augmancy. To cast this spell, you must know how to cast thorn whip. You do not need to learn or prepare this spells to cast it if you know thorn whip and have an appropriate spell slot available.

Until this spell ends, you can cast thorn whip without a target to gain a fly speed under specific circumstances. While you are in an area with a ceiling or ceiling-like canopy that is 30 feet high or less, you can cast thorn whip to gain a fly speed of 45 feet until the end of your next turn, as you propel yourself about the area with a multitude of conjured vines. Using this ability in an area with weak support could result in you falling, and the DM can always decide if a Dexterity (Acrobatics) check is necessary. For example, you may need to avoid trees or pillars in a crowded space.

At Higher Levels. When you cast this spell with a slot level of 7th level or higher, the duration of the spell becomes 1 minute with no concentration required.
