Emblems affect your online Killer or Survivor Grade. If you do well in a Trial and score a lot of points, you will receive a better rank and get more pips to increase your Grade. Emblems for Killer and Survivor Grades are reset every month on the 13th.
There are four levels of Malicious Emblem you can receive: Bronze, Silver, Gold, and Iridescent, depending on how well you do as a Killer in Dead By Daylight. You will know what Emblem rank you have received and your score at the end of the Trial.
The Malicious Emblem requires you to damage Survivors, hook them, kill them, and interrupt them in the middle of the action to score points. You can interrupt Survivors while they are repairing Generators or healing themselves, and the other actions are pretty self-explanatory.
