Damage conversion is a type of modifier that changes one type of damage into another.
Forms
Damage conversion is used by modifiers on skills, passive skills, equipment, and monsters. It comes in two main forms:
xx% of [Damage Type] Converted to [Damage Type]
- For example the level 1 Module Error: No skills found with q_where = skill.active_skill_name="Cold to Fire" support gem has the modifier 50% of Cold Damage Converted to Fire Damage
xx% of [Damage Type] Added as [Damage Type]
- For example the level 1 Module Error: No skills found with q_where = skill.active_skill_name="Poison Arrow" skill gem has the modifier Gain 30% of Physical Damage as extra Chaos Damage
The difference between these forms is the effect they have on the original damage. Converted to modifiers replace the original damage with the new damage, while Added as preserves the original damage, adding the new damage to the total. These two modifiers do not interfere with one another in any way.
Converted to
For this type of modifier, the original damage is replaced with the converted damage. The amount of any given damage type that can be converted in this way cannot exceed 100%. If the combined value of all Converted to modifiers for a given damage type is greater than 100%, the values are scaled so that the total is 100% (ref) . Conversion from skill gems takes priority over conversion from other sources (such as equipment), and is not scaled. For example:
- A player is wielding a bow that deals 100 Physical Damage,
- a Blackgleam quiver that has 40% of Physical Damage converted to Fire Damage,
- and Hrimsorrow gloves that have 25% of Physical Damage converted to Cold Damage.
- The player is using the skill
Lightning Arrow, which has 50% of Physical Damage converted to Lightning Damage
- The total in this is example is 115% of Physical Damage, and must be scaled. Since it comes from a skill gem, Lightning Arrow's modifier takes priority and is not scaled. The other two are scaled evenly to convert the remaining 50% of physical damage.
- 40 * (50/65) = 30.77% Converted to Fire Damage by Blackgleam
- 25 * (50/65) = 19.23% Converted to Cold Damage by Hrimsorrow
- In summary, the resulting converted damage would be 50 Lightning Damage, 31 Fire Damage, and 19 Cold Damage, and 0 Physical Damage, a total of 100 Damage.
- The total in this is example is 115% of Physical Damage, and must be scaled. Since it comes from a skill gem, Lightning Arrow's modifier takes priority and is not scaled. The other two are scaled evenly to convert the remaining 50% of physical damage.
Damage conversion is done before any increases, or multipliers are applied to damage guaranteeing that they are only applied once.
Damage conversion only flows in one direction between types, possibly skipping types, but never going in reverse:
- Physical → Lightning → Cold → Fire → Chaos
Added as
This modifier does not replace the original damage, instead it takes a portion of the damage and adds it to the total as a different damage type. Damage added in this way can exceed 100% of the source damage type, and does not need to be scaled. For example:
- A player is wielding a bow that deals 100 Physical Damage, and using a Blackgleam quiver, Hrimsorrow gloves, and Lightning Arrow, as in the above example.
- The Lightning Arrow skill is supported by a level 1 Module Error: No skills found with q_where = skill.active_skill_name="Added Fire Damage" gem, which has 20% of Physical Damage Added as Fire Damage.
- The result of the Converted to modifiers is the same as in the above example, the amounts are scaled to a total of 100% as normal. The Module Error: No skills found with q_where = skill.active_skill_name="Added Fire Damage" gem adds an additional 20% of the Physical Damage as Fire Damage
- In summary, the resulting converted damage would be 50 Lightning Damage, 51 Fire Damage, and 19 Cold Damage, and 0 Physical Damage, a total of 120 Damage.
Taken as
On the receiving side, damage may be taken as a different type. This is done before any sort of mitigation.

Passives
The following passives convert damage: Template:Passive table
Corruption
Corrupting a Quiver or Scepter has a chance to replace its implicit mod with
- 10-20% of Physical damage converted to Cold Damage
- 10-20% of Physical damage converted to Lightning Damage
- 10-20% of Physical damage converted to Fire Damage
Interaction with other modifiers
Converted damage is affected by modifiers that apply to be both the original damage type it was converted from, and the new damage type that is was converted to. For example Fire Damage that is added by the Module Error: No skills found with q_where = skill.active_skill_name="Added Fire Damage" gem will be affected by both increased Physical Damage modifiers and increased Fire Damage modifiers.
Also, converted damage can itself be converted. For example:
- A player is wielding a weapon that deals 100 Physical Damage,
- the player is affected by a level 10 Hatred aura which has the modifier 30% of Physical Damage Added as Cold Damage,
- the player is using an attack supported by a level 1 Module Error: No skills found with q_where = skill.active_skill_name="Cold to Fire" support gem, with the modifier 50% of Cold Damage Converted to Fire Damage
- In this example 30% of the Physical Damage is added as Cold damage, and 50% of that Cold damage is converted to Fire. The resulting damage is therefore 100 Physical Damage, 15 Cold Damage, and 15 Fire Damage.
- The Physical Damage was not the result of a conversion, and so is only affected by modifiers that affect Physical Damage, as normal
- The Cold Damage will be affected by any mods that affect either Physical Damage or Cold Damage
- The Fire Damage will be affected by any mods that affect Physical, Cold or Fire Damage
- In this example 30% of the Physical Damage is added as Cold damage, and 50% of that Cold damage is converted to Fire. The resulting damage is therefore 100 Physical Damage, 15 Cold Damage, and 15 Fire Damage.
Example calculation
Imagine a player wielding a sword that deals 100 Physical Damage, and performs an attack with the following modifiers:
- 50% of Physical Damage converted to Cold Damage from a skill gem
- 30% of Physical Damage converted to Fire Damage from gear
- 30% of Physical Damage converted to Lightning Damage from gear
- 30% of Physical Damage Added as Fire Damage from a support gem
- 15% of Physical Damage Added as Cold Damage from a support gem
- 50% of Cold Damage converted to Fire Damage from a support gem
- Adds 30 Cold Damage from a support gem
- 30% more Physical Damage from a support gem
- 70% more Weapon Elemental Damage from a support gem
- 80% increased Physical Damage with Swords from passive skills
- 30% increased Melee Physical Damage from Strength and passive skills
- 20% increased Fire Damage from passive skills
- 15% increased Cold Damage from passive skills
First off, there is more than 100% of physical damage conversion, so the values are scaled to total 100%. As a result, 50% of physical damage will become Cold Damage, 25% will become Fire Damage, and 25% will become Lightning Damage.
The Cold Damage
The amount of Cold damage that has been converted from Physical is 65 (50 Converted to, 15 Added as). 50% of the Cold Damage is Converted to Fire, leaving us with 32.5 remaining Cold Damage. This damage is affected by all Cold and Physical Damage modifiers:
- 80 + 30 + 15% = 125% increased damage
- 30% more damage
- 70% more damage
- 32.5 * (1 + 0.8 + 0.3 + 0.15) * 1.3 * 1.7 = 161.6 Cold Damage
There is also 30 Cold Damage added by a support gem which was not the result of a conversion. 50% of this is Converted to Fire, and the remaining 15 is affected by all Cold Damage modifiers:
The Lightning Damage
There is 25 Lightning Damage that was converted from Physical. This damage is affected by all Lightning and Physical Damage modifiers:
- 80 + 30 = 110% increased damage
- 30% more damage
- 70% more damage
- 25 * (1 + 0.8 + 0.3) * 1.3 * 1.7 = 116.0 Lightning Damage
The Fire Damage
There is 55 Fire Damage that was converted from Physical. This damage is affected by all Fire and Physical Damage modifiers:
- 80 + 30 + 20 = 130% increased damage
- 30% more damage
- 70% more damage
- 55 * (1 + 0.8 + 0.3 + 0.2) * 1.3 * 1.7 = 279.6 Fire Damage
There is also 32.5 Fire Damage that was converted from Cold that was converted from Physical. This damage is affected by all Fire, Cold, and Physical Damage modifiers:
- 80 + 30 + 20 + 15 = 145% increased damage
- 30% more damage
- 70% more damage
- 32.5 * (1 + 0.8 + 0.3 + 0.2 + 0.15) * 1.3 * 1.7 = 176.0 Fire Damage
There is also 15 Fire Damage that was converted from Cold. This damage is affected by all Fire and Cold Damage modifiers:
The Final Damage
In summary we have
- 29.3 Cold Damage
- 161.6 Cold Damage (from Physical)
- 116.0 Lightning Damage (from Physical)
- 279.6 Fire Damage (from Physical)
- 176.0 Fire Damage (from Cold, from Physical)
- 34.4 Fire Damage (from Cold)
For a total of 190.9 Cold, 490.0 Fire, and 116.0 Lightning Damage, a grand total of 796.9 damage.
