User blog comment:Willump/Multihit Abilities with Rylai's/@comment-8506165-20150824161304

MF R is multi-hit. I think Kata Q is as well as it applies spell effects on both the hit and the detonation. On that note, Akali Q might be as well.

Are you including DoTs? Glancing through it seems like you've left some left some out (Malza E, Swain Q/E, Morde R) but included others (Cass Q, Singed Q). Technically they're different from multi-hits (I supppose Swain Q is actually multi-hit more than DoT, at that) but they're under the same Rylai's slow classification so I don't know if you meant to test them as well or not.
