Conjure Thorns

You create a thorny area with a 10-foot radius at a point within range. Creatures in that area must make a Dexterity saving throw. On a failure, an affected creature takes 3d6 piercing damage and its speed is reduced by 15 feet for the next minute. A creature affected by this spell can make a Constitution saving throw at the end of each of its turns to end the spell’s effect.

At Higher Levels. When you cast this spell by spending Mana points equal to a 4th-level spell or higher, the damage increases by 2d6 for each level above 3rd. When cast as a 5th-level spell or higher, the piercing damage becomes incisive.
