Video + Extra Notes Video shows examples of some dash cancels that can be performed. Generally dash canceling Zhongli Hold E, Xingqiu E/Q, and Diluc N4 is best. Diluc N1's at the beginning of his field time to potentially trigger a Rain Sword. Whether he does or not depends on your swap speed, which is affected by ping.
