concentration, 5 minutes/mana

As two actions, the ground in a sphere centered on a point within 20 meters 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 meter 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 Perception check against your spell save Difficulty to recognize the terrain as hazardous before entering it.

At the start of each of your turns if the spikes are within 20 meters of you, you can cause them to move up to 2 meters in a direction that you choose. If you spend an action, you can move them up to 10 meters.


You can increase the damage by 1d4 for every two additional mana expended.
