Edit Summary: Created, Added Partial Resistance Calculations

====== Resistance ======
Resistance is a measure of a characters total protection minus the vulnerability from an attack of a given [[:attack_type|attack type]]. Resistances derived from [[:equipment:potions]] override any existing resistance.

===== Protection =====
Protection is a positive increase in resistance and is calculated using the following:

  total protection[attack_types] += ((100-current protection) x additional resistance) / 100

so if a player has 30 fire resistance and casts the [[:spells|spell]] Protection from Fire and gains 60 more fire resistance, their total protection would be:

  total protection[fire] = 30 + ((100-30) x 60)/100
  total protection[fire] = 30 + 42 = 72

As can be seen, the more sources of protection a character has, the less partial resistance each item affords. It is therefore impossible to reach 100 protection without an item that grants 100 protection. Protection cannot exceed 100. 

===== Vulnerability =====
the same formula applies (in reverse) for vulnerability:

  total vulnerability[attack_types] -= ((100-current vulnerability) x additional vulnerability) / 100

so if a player has -5 resistance from their god and -15 resistance from their weapon:

  total vulnerability[fire] = -5 - ((100-5) x 15)/100
  total vulnerability[fire] = -5 - 14.25 = -19

As can be seen, the more sources of vulnerability a character has, the less partial resistance each item affords. It is therefore impossible to reach 100 vulnerability without an item that grants 100 vulnerability. Vulnerability cannot exceed 100. 

===== Total Resistance =====
Resistance is the total protection minus the total vulnerability:

  total resistance[fire] = total protection[fire] - total vulnerability[fire]

Combining the above scenario, our player has:

  total resistance[fire] = 72 - 19
  total resistance[fire] = 53

It should be noted that vulnerability cannot be easily overcome by additional resistance and can have a significant impact even from small total vulnerabilities.
