Dead by Daylight is an asymmetrical horror game where one Killer has to face four Survivors, which have to repair generators and escape through the Exit Gates. To stop and catch Survivors, the Killer can equip Offerings and Perks, which also allow him to kill Survivors instantly.
To mori a Survivor in Dead by Daylight, the Killer has to equip a Memento Mori Offering, which can be found in the Bloodweb. Perks such as Hex: Devour Hope or Rancor also enable the Killer to kill Survivors instantly under certain conditions.
On the other hand, only a few Killers have a Memento Mori built into their power, including The Pig (Amanda Young/Jigsaw) and The Executioner (Pyramid Head).
In the case of The Executioner, if a Survivor reached the second stage on a Hook or in a Cage of Atonement, Final Judgement (Ability) can be used to execute him.
To instantly kill a Survivor with The Pig, the Killer has to put a Bear Trap onto the Survivor. Whenever a Generator is completed, all currently inactive Reverse Bear Traps will become active. Once the timer expires, the active Reverse Bear Trap will automatically sacrifice the Survivor wearing it.
Attempting to leave the Trial Grounds through an Exit Gate with an active Reverse Bear Trap will cause the timer to expire immediately and sacrifice the Survivor.
How do you activate Memento Mori Dead by Daylight?
To be able to mori Survivors in DBD, the Killer has to equip one of the three Memento Mori Offerings (Cypress/Ivory/Ebony). However, Survivors cannot be executed instantly after the Trial started.
To activate a Memento Mori, the Killer has to put a Survivor into the Dying State. Press the Active Ability button while standing over a dying Survivor to activate the Memento Mori.
Depending on which of the three Mori Offerings you equipped, Survivors have to progress two Hook Stages before the mori can be executed. The only exception is the Cypress Memento Mori, which does not require any Hook progression.
Cypress Memento Mori:
Grants the ability to kill the last remaining Survivor by your hand during the next Trial.
“You worked well, the last one is yours.”
Ivory Memento Mori:
Grants the ability to kill one Survivor, who has progressed two Hook Stages, by your hand during the next Trial.
“Grant me the favour of killing one.”
Ebony Memento Mori:
Grants the ability to kill all Survivors, who have progressed two Hook Stages, by your hand during the next Trial.
“I could swear It spoke to the beast. It came to a halt, as if calmly listening to the leaves rustling, and then… grinned.”
How to get a Memento Mori in Dead by Daylight?
There are three different Memento Mori Offerings currently available for all Killers, but they are not available immediately.
To get a Memento Mori, the player has to spend Bloodpoints in the Bloodweb to increase the level of a Killer. Sometimes, one of the three Mementos (Cypress/Ivory/Ebony) will appear in the Bloodweb and can be obtained for 4.000-7.000 Bloodpoints.
Cypress Mori’s Offerings are the most common of the three; Ebony Memento Mori’s are the rarest. That said, you can find Ebony Memento Offerings back to back if you’re lucky.
Side Note: If you bring a Memento Mori Offering to the game as Killer, Survivors cannot see which of the three Memento Mori’s you equipped.
