When you Sustain this spell, each creature grabbed or restrained by the plants takes 4d6 piercing damage.

Traits
An action with this trait requires a degree of mental concentration and discipline.
Focus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
Vegetable creatures have the plant trait. They are distinct from normal plants. Magical effects with this trait manipulate or conjure plants or plant matter in some way. Those that manipulate plants have no effect in an area with no plants.
