Ability Concept: Seeding

You toss a seed. the seed grows and expands towards the bushes within a area radius. once in the brush it makes the brush thicker and into an impassible barrier.
the barrier can be auto attacked to cut it down.

the plant takes 15/8/5/2 secs to finish the growth. the plants have 5 health to chop down.

they last 60-180 secs.

---edit--- could have the thicket destroyed when the seed/root is destroyed so placing this down would force people to go around to remove the obstruction.

think about blocking off the TRI in bot lane. enemy would have to come around to free the obstacle out.
