Damage conversion

Not to be confused with Damage taken as.

Damage conversion is a mechanic that changes the damage type from a hit into another damage type. Damage conversions do not apply to damage over time.

Path of Exile: Damage Conversion

Mechanics

Damage conversion is done before any increases, or multipliers are applied to damage guaranteeing that they are only applied once. However, converted damage is affected by modifiers that apply to both the original damage type it was converted from, and the new damage type that it was converted to.

Damage conversion is used by modifiers on skills, passive skills, equipment, and monsters. It comes in two main forms:

• #% of [Damage Type] Converted to [Damage Type]
• #% of [Damage Type] Added as [Damage Type] or Gain #% of [Damage Type] as Extra [Damage Type]

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.

Conversion is applied on your character to your damage stats, which have minimum and maximum values. You can see that this happens because you can see that the min and max values of each type are already calculated on your skill, accounting for conversion. For example, assuming that you convert Physical skill 50% to Cold and 50% to Lightning, there will be enough variance in damage ranges to alternate which damage type is higher, enabling the use of .

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%. Conversion from skill gems (both active and support skill gems) take priority over conversion from other sources (such as equipment), and is not scaled. The game does not distinguish between damage converted by passives and by gear; this may be of some importance when dealing with Avatar of Fire.

Damage conversion only flows in one direction between types, possibly skipping types, but never going in reverse:

Physical → Lightning → Cold → Fire → Chaos

The reason is that conversion is an iterative process from one damage type to the next, so if it goes backwards there'll be an infinite loop. Converted damage can be converted further itself.

Example ▾ [Expand] ▾

• A player is wielding a bow that deals 100 Physical Damage,
• a quiver that has 50% of Physical Damage converted to Fire Damage,
• and gloves that have 50% of Physical Damage converted to Cold Damage.
• The player is using the skill , which has 50% of Physical Damage converted to Lightning Damage

The total in this is example is 150% 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 proportionally to convert the remaining 50% of physical damage.

50 * (50/100) = 25% Converted to Fire Damage by Blackgleam

50 * (50/100) = 25% Converted to Cold Damage by Hrimsorrow

In summary, the resulting converted damage would be 50 Lightning Damage, 25 Fire Damage, and 25 Cold Damage, and 0 Physical Damage, a total of 100 Damage.

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.

Example ▾ [Expand] ▾

• A player is wielding a bow that deals 100 Physical Damage, and using a quiver, gloves, and , as in the above example.
• The skill is supported by a level 1 gem, which has 25% 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 gem adds an additional 25% of the original Physical Damage as Fire Damage

In summary, the resulting converted damage would be 50 Lightning Damage, 50 Fire Damage, and 25 Cold Damage, and 0 Physical Damage, a total of 125 Damage.

Added as chaos

Please note that there are also items which grant the Unholy Might buff, which grants 30% of physical damage as extra chaos damage, but those are not listed here.

A notable interaction of the mods #% of Elemental Damage as Extra Chaos Damage and #% of Non-Chaos Damage as Extra Chaos Damage is that they apply for each valid damage type rather than a total of the valid damage types.

For example, the mod #% of Elemental Damage as Extra Chaos Damage would instead translate to:

• #% of Lightning Damage as Extra Chaos Damage
• #% of Cold Damage as Extra Chaos Damage
• #% of Fire Damage as Extra Chaos Damage

And the mod #% of Non-Chaos Damage as Extra Chaos Damage would instead translate to:

• #% of Physical Damage as Extra Chaos Damage
• #% of Lightning Damage as Extra Chaos Damage
• #% of Cold Damage as Extra Chaos Damage
• #% of Fire Damage as Extra Chaos Damage

Example ▾ [Expand] ▾

• A player is wielding a bow that deals 100 Physical Damage,
• a quiver that has 50% of Physical Damage converted to Fire Damage,
• and gloves that have 50% of Physical Damage converted to Cold Damage,
• and finally, a rare amulet with the mod 10% of Non-Chaos Damage as Extra Chaos Damage.
• For the purposes of this example, let's assume the player has no other damage modifiers.

The player has 100 physical damage, 50 of which is converted to fire from and 50 of which is converted to cold from .

The player has 20 chaos damage:

10 from 10% of Non-Chaos Damage as Extra Chaos Damage applying to the 100 base physical damage.

5 from 10% of Non-Chaos Damage as Extra Chaos Damage applying to the 50 converted cold damage.

5 from 10% of Non-Chaos Damage as Extra Chaos Damage applying to the 50 converted fire damage.

Therefore in total, the player has:

50 Fire + 50 Cold + 20 Chaos = 120 total damage.

Passive skills

The following passives convert damage or add damage as another type

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.

Since 100% of the physical damage has been converted, there is no remaining pure physical damage; if there were, this unconverted damage would be affected by all Physical Damage modifiers.

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:

15% increased damage

70% more damage

• 15 * (1 + 0.15) * 1.7 = 29.3 Cold Damage

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:

20 + 15 = 35% increased damage

70% more damage

• 15 * (1 + 0.2 + 0.15) * 1.7 = 34.4 Fire Damage

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.
