Type	Attributes Combat Game Systems

See also: Critical Rate and Critical Damage

Critical Hits refers to the random occurrence of an attack dealing increased damage to an opponent.

If the attack is a Critical Hit, the CRIT DMG multiplier is applied:

${\text{DMG}}_{\text{CRIT}}={\text{DMG}}\times (1+\%{\text{CRIT DMG}})$

The base CRIT Rate for most characters is 5%, while the base CRIT DMG is 50%. These attributes can be increased by:

• Elemental Resonances
• Talents
• Constellations
• Artifacts
• Weapons
• Food
• Character Ascension Bonuses

Note that Sangonomiya Kokomi's CRIT Rate is decreased by 100% via Flawless Strategy, which means her base CRIT Rate will start negative. A negative CRIT Rate means that attacks will never CRIT.

Critical Hits cannot trigger on enemies that are immune to the type of damage dealt or during enemy i-frames.

Critical Hits appear as larger-font numbers on the screen compared to non-crit hits. Another way to tell if you scored a critical hit is to watch the DMG dealt; a critical hit will have damage multiplied.

CRIT Optimization

Main article: Attribute Optimization

There is a general rule to maximize the product of CRIT DMG and CRIT Rate to maximize the expected DMG.

Let r be the CRIT Rate probability ($r\leq 1$) and d be the CRIT DMG ($d\geq 0$) in decimal form (for example, 150% CRIT DMG would be $d=1.5$).

Suppose the DMG is x without CRIT. The expected damage is therefore:

$E({\text{DMG}})=(1-r)x+r(1+d)x=x(1+rd)$

In general, the goal is to maximize this product by making r and d as large as possible. However, by introducing a constraint on the relation between r and d, it is possible to calculate an optimal ratio between the two. The rule of thumb is to aim for a 2:1 ratio between CRIT DMG and CRIT Rate. See Attribute Optimization for full derivations of these results.

Guaranteed CRIT Hits

General

• Having 100% or more CRIT Rate means that attacks will always critically hit.
• Attacks on an enemy's weak point guarantees a Critical Hit. Note that Bosses do not have weak points.
  • On Elemental Lifeforms, this is usually dead center.
  • On Mystical Beasts, this is on the face of Whopperflowers or Geovishaps.
  • On Ruin Machines, this is on the exposed cores.
  • On most human enemies (Kairagi, Nobushi, Treasure Hoarders, Fatui, etc.), this is directly on the head.
  • On Hilichurls, this is directly on the head.
