Beginning at 6th level, nettles and barbs grow menacingly
long and sharp while in your presence. Their typical nuisance
evolves into a debilitating, deadly hazard. When you cast a
spell that has an area of effect, you can also create a thicket
of thorns originating anywhere in the spell's area of effect
that takes up a 10 feet diameter.
When a creature starts its turn in the thicket's area, and
when it enters the area, it takes damage from the thorns. The
damage of these thorns are listed in the Wicked Thicket table
below.
Wicked Thicket
Druid Level Damage
6th 2d4 Piercing
10th 2d4 Piercing + 1d4 poison
14th 2d4 Piercing + 2d4 Poison

When you deal damage with the spells spike growth, or
wall of thorns you may add the poison damage from this
feature to that spell's damage.
