Dead by Daylight is a game that constantly has in game events, but also specific actions in matches that are significant to the outcome of the match. Examples could be the start of a chase, injuring a survivor, escaping chase, hooking a survivor/being hooked, being saved from basement hook/encroaching shack to save a teammate from basement, but specifically Mori's should definitely be considered an event regardless. It initiates a cinematic execution that as a killer you have to earn the right to the kill.
