Give this character a power action; place up to 6 hindering terrain
markers in distinct, adjacent squares that are all within this character’s range (minimum range value 4). At least one of the terrain markers must be within line of fire when it is placed. The terrain markers remain until the beginning of your next turn. Characters that occupy these terrain markers modify their attack value by -1 unless they can use Smoke Cloud or ignore hindering terrain for line of fire purposes.
