^ That's not what he's fully asking, he's asking if rammus has 500 movepseed and you slow him for 20%, you will get 100 movespeed, now if rammus is powerballing at the moment of impact of seismic shard, and rammus over the course of the slow duration increases his movespeed up to 1k, will you then have 200 movespeed or 100 movepseed?

I would assume that you would only have the 100 due to the nature of the speed buff persisting even if the target dies from seismic shard or during the slow, so I'd assume that once it calculates the buff it just leaves that static buff on malphite. But I'm only speculating.
