Serration is a hidden form of damage in Bloodborne.

Saw cleaver 2


Serration is a hidden damage modifier, inherent in weapons, which deals 20% more damage against "Beast-type enemies".

This damage is applied before bonuses such as the open foe bonus for a multiplicative effect. However, there are two category of beings that, though classified as "Beasts", are rather, in the sense of them being animals, rather than "True" Beasts (check the page Beasts to understand the distinctions).

As there are many bosses who are indeed "True" Beasts, it would be wise to upgrade one of these weapons along with your preferred weapon.

(serrated attacks always have a 20% bonus damage against beasts)

Enemies weak to Serrated damage

Bosses weak to Serrated damage


  • Serrated damage only affects "True" Beasts.
  • If a player becomes part Beast by the use of Beast's Embrace, the Serration bonus does not apply to them.


  • Serration is used, in-lore, to cause bloodletting on Beasts.
  • The reason that the Serration bonus does not apply to players who use Beast's Embrace, is likely because becoming a Beast is not just a physical state, but rather a state of mind. In other words, since the players are still conscious of their action, they cannot be Beasts, and therefore the effect does not apply.
