OK, so.
Pick one, two, or three creatures.
Against each of those creatures, make 3 attacks. If the first attack hits, you do 1[w]+mods. If the second attack hits it takes 1[w]+mods and you get to stun, if the third attack hits, you do 3[w]+mods.
Obviously the status effects also apply.
EDIT: This power is extremely poorly phrased, incidentally.
Surprise no one has pointed out that after the first attack, hit or miss, the target is Dazed. Attacks 2 and 3 will have auto-CA.
