It will block parrrley, it will block siphoning strike, hell it will even block sonas passive, but it wont block mystic shot because its a spell. Basically it blocks any auto attack, and anything that activates with that attack. IE it will block vorpal spikes from activating if cho attacks you when ur passive is up, but on the next attack the spikes will activate. Additional effects DO apply tho. IE. gangplank parrrleys you, the damage is blocked, but u still get his passive on you.
-edit- It appears I'm wrong, it WILL block the dmg from mystic shot...
