Spike Growth

2nd-Level Transmutation
Casting Time: 1 action
Range: 150 feet
Components: VSM (seven sharp thorns or seven small twigs, each sharpened to a point)
Duration: (C) 10 minutes

The ground in a 20-foot radius centered on a point within range twists and sprouts hard spikes and thorns. The area becomes difficult terrain 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 at the time the spell is cast must make a Wisdom (Perception) check against your spell save DC to recognize the terrain as hazardous before entering it.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the area of the spell increases by 10 feet for every two slot levels above 2nd.
