Order of operations
The list below displays the order of operations when an attacker attempts to damage a defender:
- Initial damage
Damage sources have a base damage that can be increased by various stats. Stats are only applied once per calculation.
- Flat damage
- Damage conversion
- 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.
- Converted to modifiers changes one type of damage into another, for example #% of Cold Damage Converted to Fire Damage.
Converted damage can take benefit of bonuses for the damage type it was before and what it converted into.
Hits can be rolled as a critical strike which multiplies the damage by 150% by default.
Incoming, damaging hits can be shifted to another damage type. It is usually done by utilizing an item which offers the #% of X Damage taken as Y modifier, for example:

resulted in some surprising material discoveries.. Avoiding damage stops the damage of a hit. It still counts as a hit, even if it only is 0 damage.
- Elemental and chaos damage is mitigated by its respective resistance.
- Physical damage is mitigated by the sum of all #% additional Physical Damage Reduction modifiers, up to its 90% cap. These modifiers can be calculated from:
- Armour, which grants damage reduction relative to how much Armour you have compared to the initial physical damage hit.
- Other sources of flat physical damage reduction, such as:
- Endurance charges
- Basalt FlaskBasalt FlaskLasts 4.50 Seconds

- Non-chaos damage damages energy shield protecting life until it's depleted, by default.
- For Mind over Matter users, #% of the remaining damage is removed from mana. Mind over Matter only applies if the hit is damaging life.
Damage over Time generally follows the same principle, however this damage source doesn't hit which means that it ignores evasion, damage shifts, armour and other mechanics that requires a hit. Other sources of physical damage reduction will apply as usual though. 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.
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. 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
