Critical Hit

> Game rules

A critical hit is like a standard hit with a bonus on the result of the action. Depending on the Agility of the entity, the probability of making a critical hit is given by the formula:

Critical Hit Probability = Agility of caster / 1000

Examples:

0 agility or less => 0% critical hit chance
100 agility => 10% chance
500 agility => 50%
1000 agility or more => 100%

The bonus given to a critical hit is 30% or 1.3 * the base effect (in the code you can use the constant CRITICAL_FACTOR to free you from any changes in ratio based on updates).

All the effects can crit, but some do not change the result, for example antidote, postage, boxing glove, grappling hook, teleport... in critical hit will give the same result as in normal hit.

The only exception to the 30% bonus is for summons, if you perform a summon with a critical hit all the summon's stats are boosted by only 20%.

For items with multiple effects the bonus is applied to all effects.

For damage done by a critical hit, the erosion rate is increased by 10%.

For a critical POISON effect, the rate of erosion increases from 10% to 20% of the damage inflicted.
For every other critical effect, the erosion rate therefore increases from 5% to 15% of the damage inflicted.
