All 3 Q shurikens will do damage, but the third shuriken won't do much. They do 50% of the damage the last one did, so the original would do 100%, then the second 50%, and then the third 25%. Since you're using your ult to get all 3 possible shurikens, then chances are they'll die from just the two and the rest of your combo anyway so I wouldn't use your escape to get a measly 25% extra damage. --- I'm very passionate about my Scrolls. I love the way they feel against my skin in the moonlight.
