Overgrowth

With a wave of your hand, you cause thick plants to sprout wildly from the ground, forming a complex weave of undergrowth that easily tangles any who try to move through it. This spell will work anywhere that plant life could possibly grow—essentially anywhere except solid rock, though flagstones and cobblestones will permit such rampant growth.

Make a Spellcasting skill check against a TN of 13.

• Success: All squares in a Close Burst 5 are now difficult terrain.
• Failure: All squares in a Close Burst 3 are now difficult terrain.

The plant growth remains once you cease to Sustain this Spell, but it loses some of its density. It no longer counts as difficult terrain.
