Critical hit

All weapons and most spells have a chance of getting a **critical hit**. For weapons and many spells, this means doing higher damage. However, a wide variety of critical hit effects exist, so check the spell to be sure what it does.

## Base CH

The base critical hit (CH) is displayed on the spell or weapon description window under **Critical Hit**:

A Critical Hit of 1/50 means that the spell/weapon has a probability of producing a critical hit 1 time out of 50, in another words, it has 2% chance of dealing critical hit.

## Effect

The effect of a critical hit generally implies increased damage for a weapon or improved efficiency for a spell.

* For a weapon : Effect is described under **Critical hit bonus**.
* For a spell: Effect is described on the **Critical** tab.

## Actual CH

The actual CH is based on the base CH as modified by the equipment and the player's characteristics. For spells and for the *currently equipped* weapon, it can be seen on the spell or weapon description window under **Current Critical Hit** (see figures above). It can also be displayed during a fight by hovering your mouse over the close combat or spell icon.

### Modifiers

Actual CH is or can be affected by:

* the player's Agility
* equipment (see Category:Critical hit equipment)
* spells (eg. Critical Shooting)
* bonus gained from your order

Equipment and spell bonuses are subtracted from the denominator of the base CH. Thus a 1/50 critical rate becomes 1/40 with a +10 CH bonus.

### Calculation

The following formula comes from a ~~stickied post~~ on the official forum.

* Agility = a, your player's agility (a is always >= 0)
* Basecrit = x, where 1/x is the weapon crit rate
* Equipcrit = y, where y is the total +crits on a character
* Finalcrit = 1/z, where z = floor( (x-y) \* ( (e \* 1.1) / ln(a + 12) ) )

Notes:

* The stated formula was obtained empirically (reverse-engineered, so to speak) and may or may not correspond to the actual game code. The variance in low and high crit rates is explained by the following two statements:
* If 1/z is a lower (worse) crit rate than 1/(x-y), then the final crit rate is 1/(x-y).
* If 1/z is a higher (better) crit rate than 1/2, then the final crit rate is 1/2.
* e is Euler's number, a mathematical constant.
* ln is the natural logarithm

### Worked Example

There is a fairly simple method to calculate the final chances of a CH, based on this Agi reference table:

* 1/3 -> 1/2 = 8 agility
* 1/4 -> 1/2 = 42 agility
* 1/5 -> 1/2 = 134 agility
* 1/6 -> 1/2 = 384 agility
* 1/7 -> 1/2 = 1060 agility
* 1/8 -> 1/2 = 2892 agility

You need to combine the information from this table with your current CH rate. An example is given below:

* With a 1/45 weapon and 150 Agi, we know that the Agi would get 1/5 to 1/2 so we need to bring the 'current CH' from 1/45 to 1/5; so the CH bonus from equipment needs to be 40.
* With a 1/50 spell and 750 agi, we know that the Agi gives get 1/6 to 1/2, so we need to bring the 'current CH' from 1/50 to 1/6; so the CH bonus from equipment needs to be 44.
