There are a number of steps involved in deciding whether attacks and spells hits or not and how much damage is done to the enemy.

Order of operations

The list below displays the order of operations for giving or receiving damage:

  1. Initial damage:
    Attacks and spells have a base damage that can be increased by various stats. Stats are generally only applied once per calculation, however in some cases it is possible to benefit from stats twice (e.g. burning).
    1. Flat damage
      • Local modifiers apply on the relevant source, for example most modifiers on weapons.
    2. Damage conversion
      • Converted to modifiers changes one type of damage into another, for example #% of Cold Damage Converted to Fire Damage.[1][2]
      • Added as modifiers adds a percentage of one damage type as another damage type, for example Gain #% of Physical Damage as Extra Cold Damage during effect or You and nearby allies add #% of your Physical Damage as Cold Damage.[1]
    3. Damage modifiers
      • Global modifiers apply globally, for example the many modifiers on the skill tree.
      Damage based on and converted damage benefits from the source damage type bonuses as well.
  2. Avoiding the hit:
    1. Evasion of attacks.[3]
    2. Dodge and Spell dodge.[3]
  3. Avoiding the damage:
    1. Block and Spell block.[3]
  4. Damage shift:
    Part of incoming damage can be shifted to another type of damage.[4] It is usually done by utilizing an item which offers the #% of X Damage taken as Y modifier, for example:
    • Module Error: More than one result found for item using search term "item_name = Lightning Coil". Try using the page parameter instead
    • Cloak of FlameCloak of Flame
      Scholar's Robe
      Energy Shield: (43-53)
      Movement Speed: -3%
      Requires Level 18, 55 Int+(50-75)% to Fire Resistance
      (40-75)% increased Ignite Duration on Enemies
      Reflects 100 Fire Damage to Melee Attackers
      40% of Physical Damage taken as Fire Damage
      He who sows an ember shall reap an inferno.
    • Module Error: No results found for item using search term "item_name = Incandescent_Heart"
    It is important to note that this is not damage conversion,[4] as shifted part of damage does not retain its original damage property so it won't get mitigated either twice or by the more favorable method. For example, if some of the incoming damage is shifted to or from physical, the after-shift value is used in the armour calculation.
  5. Damage mitigation:
  6. Damage taken:
    After damage mitigation, modifiers to Damage taken are applied. Flat amounts are applied first, then the sum of all increases/reductions and lastly with more/less multipliers applied separately:[6]

    The portrait reflected his pain,
    a pain that she could never see.

    Unrelenting
    3 #% more/less X Damage taken Arctic Armour
  7. Taking the final damage:
    1. Non-chaos damage normally damages energy shield protecting life until it's depleted.
    2. For Mind over Matter users, #% of the remaining damage is removed from mana. Mind over Matter only applies if the hit is damaging life.

    Chaos damage always bypasses energy shield. This applies regardless if energy shield is protecting life or mana.


Damage over Time generally follows the same principle, except for being unaffected by damage shifts and armour (the latter needing a hit to calculate reduction), other sources of physical damage reduction will apply as usual. As for damage taken step, modifiers that generally affect Damage taken or Damage taken from Damage over Time will apply, but Damage taken from Hits won't.

Unlucky

If a damage roll is unlucky, the damage calculation will be rolled twice and the lower value will be chosen. Rolls to crit/evade/dodge/block are unchanged and only happen once.[7] This can effectively reduce damage by up to one third if the damage has a very low minimum, with the benefit decreasing rapidly: Damage with minimum at half the maximum will only be reduced by one ninth. Currently unlucky is only found on the unique ring Lori's LanternLori's Lantern

By its light, Lori led her young charges to safety
and bound up their wounds.
Her sword arm was iron, yet her heart gentle
and proof against hate.
