You can read above: "Clearing any of the following two nodes once with a S Rank will result in an increase of Aerial Attack"

So you don't need to go back to E5 I node. You can enable the debuff with S rank at ONLY TWO of the listed node.

However, the debuff will be more effective if you actually S rank all the nodes.

And the debuff will not reset until the end of the event. you only need to do it once.
