Blowing Leaves

You can cast a stream of leaves from your hand at a foe
up to 100 yards away, borne on a current of air. The
whirling leaves occupy a two-yard-radius area. They cause
no injury but interfere with vision for 10 seconds, giving -2
to all Vision rolls to see into, out of, or through the area.
Aiming the leaves requires a roll against Innate Attack
(Projectile) plus Talent; standard range penalties (p. B550)
apply. Wind or rain can deflect your aim (GM’s call). The
attack can be blocked with a shield, but not parried. If you
miss, or the target defends, see Scatter (p. B141).
Extra effort can make the interference more severe:
another -1 to Vision for each -10 to Will. You may make a
Power Block (p. 11) with Blowing Leaves.
Statistics: Obscure 2 (Vision; Blockable, -5%; Chi, -10%;
Elemental, -10%; Ranged, +50%) [5].
