Senna gets a wraith from Illaoi E Spirits

Pretty self-explanatory. When Illaoi lands an E and the spirit spawned by it dies near Senna, it drops a wraith for Senna to collect.

If this is intentional, a Senna + Illaoi botlane would be quite the memeworthy duo. Illaoi lands E's for Senna to farm stacks off of and scales to oblivion.
