You gather wisps of primal magic and form them into a spectral trap, one that lies hidden from your enemies' view. When a foe stumbles into the trap, a thick vine emerges from the ground to wrap around it.

Encounter   ✦     Primal, Zone
Minor Action      Ranged 10

Target: One square

Effect: The target becomes a zone that lasts until the end of the encounter or until an enemy enters it. Without a Perception check (DC 10 + your level + your Wisdom modifier) your enemies notice neither the zone nor your use of this power. When an enemy enters the zone, the enemy's movement ends, you can slide it up to 4 squares, and it is slowed until the end of its next turn.
