Tall Grass

2nd-level transmutation

Casting Time:1 action

Range:150 ft.

Components:V, S, M (a blade of grass)

Duration:Concentration, up to to 1 hour

You cause grass in a 20-foot square to grow to a height of 10 feet, making all vision through the tall grass heavily obscured beyond 5 feet.

Large or smaller creatures within the tall grass are lightly obscured when within 5 feet of another creature. Huge or Gargantuan creatures are obscured within the tall grass only if they are prone. Creatures within the area have disadvantage on their first saving throw against a plant-based spell (such as entangle or plant growth).

You can increase the size of the square to 30 feet by making the grass 5 feet tall. If you do, vision is heavily obscured beyond 5 feet at a height of 5 feet, Medium or smaller creatures in the area are obscured when within 5 feet of another creature, and Large or Huge creatures can only be obscured if they are prone.

This spell cannot be cast indoors, underground, or on a worked stone surface, nor in arctic terrain such as ice or very deep snow. It can be cast on any other type of horizontal natural surface. If cast underwater or in boggy terrain, tall grass grows from the ground up and may be partly submerged and partly extending above the waterline.
