Cassia’s Fend ability is able to track Tracer when Tracer is recalling.
I was just playing against some AIs a few minutes ago playing as Tracer when I found myself low on health so I decided to recall at the same time the AI Cassia used Fend went all the way around the wall to my last position then teleport-ed to my current position that I recalled to and killed me.
A lot of abilities will track her through recall. For example Kael’s Pyroblast.
Once she starts channelling fend she will not follow you and you can recall safely. However before then if you recall it might retarget and change direction to where you are recalling to.
I just never had that happen before so I was caught off guard by it
