Casting Time: Action Range: 150 feet Components: V, S, M (seven thorns) Duration: Concentration, up to 10 minutes
The ground in a 20-foot-radius centered on a point within range sprouts hard spikes and thorns. The area becomes for the duration. When a creature moves into or within the area, it takes 2d4 Piercing damage for every 5 feet it travels.
The transformation of the ground is camouflaged to look natural. Any creature that can't see the area when the spell is cast must take a action and succeed on a Wisdom ( or ) check against your spell save DC to recognize the terrain as hazardous before entering it.
