The Dead by Daylight developers have just unveiled all the changes coming to patch 8.3.0 of the famous asymmetrical horror game. This update brings a massive amount of bug fixes, balance changes, and a rework to one of the oldest systems in the game.

Before the patch hits live servers, you may want to know what perks, add-ons, and Killers have been changed. Here's everything in Dead by Daylight's 8.3.0 update.

On top of the usual bugfixes found every patch, there are significant changes to everyone's least favorite killer, The Skull Merchant, changes to both Survivor and Killer perks, and an update to the Mori's execution system.

Here's a full breakdown of the main changes in patch 8.3.0.

In Dead by Daylight, Killers can bring a Mori to execute Survivors on their final hook state. This execution always plays a special animation unique to each Killer and prevents Survivors from saving their dying teammates with flashlights or palette stuns. If a Killer brought a rarer Mori, they could execute more than one Survivor.

Patch 8.3.0 has changed the long-standing Mori system. Killers can now only execute the final Survivor. This means all the Mori offerings have been reworked, and instead provide bonus bloodpoints for performing the execution. There's also a new system that hides clutter while the Mori is performed, so the animation is no longer blocked by walls, grass, or boxes.

Killers that have Moris built into their kits, such as Pyramid Head or Sadako, will still be able to execute multiple Survivors with their Killer Powers.

There are 10 Survivor perks that have received changes in the DBD patch. Here's a full list of all updated Survivor perk at tier three.

Ten Killer perks have also been updated. Here's a full list of the updated Killer perks at tier three.

Only four Killers were changed this patch. Notably, The Skull Merchant has been completely gutted with six major nerfs, making everyone's least favorite Killer significantly weaker.

The Skull Merchant no longer receives speed boosts when Survivors are scanned, and her drones apply a five percent hindered effect instead of 10. Her drones only have one scan line now, and this beam is always visible.

The Twins also received minor nerfs that make Victor's respawn timer longer after he is crushed, and increase the cooldown of his lunge attack. The Hillbilly has been slapped with a couple of nerfs, making his overdrive state shorter and increasing the amount of time it takes to recover after missing a chainsaw attack.

Finally, The Unknown got a quality-of-life update. This monster now has a new HUD that correctly displays the teleport cooldowns and they can recover from teleporting 15 percent faster. To compensate, their movement speed decreases quicker while charging a ranged attack.
