One of Cassiopeia's abilities that slow your enemies goes invisible after cast to your enemies making this ability very hard to dodge, almost impossible.

"Report a Bug" is a board for technical reports of problems occurring in the game. Your report is vague and does not follow the submission instructions making it completely useless.
Thank you for trying to be of assistance, but ineffectual reports such as this are only a hindrance to bug fixing efforts of Riot Games.
