Health

Other

Like most attribute values, Health is increased by single multiplier formed from effects that additively stack with each other. The health gained from leveling is an exception, stacking additively with base health before multipliers

Total Health = (Base Health + Warframe Rank Bonuses) × (1 + Modifier from Mods) + Other Bonuses

• Base Health refers to the Warframe's health at Rank 0.
• Warframe Rank Bonuses are increases to a Warframe's health that apply as the Warframe goes from rank 0 to 30. These are normally +100 at rank 30, though there are exceptions. Importantly, unlike capacity, they are not impacted by mastery rank, meaning that two players with newly built frames will always have the same bonuses regardless of their mastery.
• Modifier from Mods is from mods such as  Vitality and  Vigor, increasing the Health by 100% and 50% at their maximum ranks, respectively. The  Physique Aura mod increases it by 20% at maximum rank. Each additional squad member that brings Physique will increase your Modifier by an additional 20%, to a maximum 80% addition in a four-player mission, which can be further increased with  Coaction Drift. Lastly, the bonus from some Arcane helmets contribute to this modifier.

Health Reduction

Having equipped a Bleeding Dragon Key reduces total health by 75%, after all other calculations. During missions, this is indicated by a symbol to the left of the shield/health bar (shown on the right).

Healing

Main article: Healing

Unlike shields, health does not naturally regenerate over time, except when either the  Rejuvenation or  Dreamer's Bond Aura mod is equipped by at least one member of the squad. Otherwise, damage inflicted upon health must actively be healed by picking up Health Orbs, by receiving the effects of certain Warframe abilities, or by using certain mods, weapons, consumable equipment, or Arcane Enhancements.

Bleedout & Death

Main article: Death

When health is reduced to 0, Warframes enter the Bleedout state. In bleedout, Warframes can barely move and are restricted to firing their sidearm. If they do not receive the appropriate attention from an ally within 20 seconds, they are killed in action. It is quite difficult to complete missions successfully when all players are dead, so players typically strive to keep health above 0 at all times.

Effective Health

Damage calculations get complicated when damage resistances are involved. Effective health (EHP) is a common metagame concept which states that because each hit point you have actually absorbs more than one point of damage, you effectively have more hit points than indicated. In WARFRAME, effective health can be increased by armor, sources of damage reduction, negative damage type modifiers, resistance mods, and health classes.

Calculation

Effective health against a particular damage type can be calculated as such:

${\displaystyle { \begin{aligned} \text{EHP} &= \text{Nominal Health} \cdot \frac{\text{Net Armor} + 300}{300} \cdot \frac{1}{1 - \text{Net Damage Reduction} } \cdot \frac{1}{1 + \text{Damage Type Modifier} } \\ \qquad &= \frac{ \text{Nominal Health} \cdot (\text{Net Armor} + 300) }{ 300(1- \text{Net Damage Reduction})(1 + \text{Damage Type Modifier}) } \end{aligned} } }$

Nominal health refers to listed health points as displayed in-game; in other words, it is the total health after mods and buffs are applied

Net damage reduction refers to total damage reduction outside of armor

Enemy Health Scaling

Main article: Enemy Level Scaling

For health, the ranges of level differences from base to current level at which scaling transitions is between 70 & 80.

Grineer

The formula by which Grineer health scales is as follows:

${\displaystyle f_{1}(x)=1+0.015(x-{\text{Base Level}})^{2.12}}$

When Current Level - Base Level < 70

${\displaystyle f_{2}(x)=1+{\frac {24{\sqrt {5}}}{5}}(x-{\text{Base Level}})^{0.72}}$

When Current Level - Base Level > 80

Corpus

The formula by which Corpus health scales is as follows:

${\displaystyle f_{1}(x)=1+0.015(x-{\text{Base Level}})^{2.12}}$

When Current Level - Base Level < 70

${\displaystyle f_{2}(x)=1+{\frac {30{\sqrt {5}}}{5}}(x-{\text{Base Level}})^{0.55}}$

When Current Level - Base Level > 80

Infested

The formula by which Infested health scales is as follows:

${\displaystyle f_{1}(x)=1+0.0225(x-{\text{Base Level}})^{2.12}}$

When Current Level - Base Level < 70

${\displaystyle f_{2}(x)=1+{\frac {36{\sqrt {5}}}{5}}(x-{\text{Base Level}})^{0.72}}$

When Current Level - Base Level > 80

Corrupted

The formula by which Corrupted health scales is as follows:

${\displaystyle f_{1}(x)=1+0.015(x-{\text{Base Level}})^{2.1}}$

When Current Level - Base Level < 70

${\displaystyle f_{2}(x)=1+{\frac {24{\sqrt {5}}}{5}}(x-{\text{Base Level}})^{0.685}}$

When Current Level - Base Level > 80

Murmur, Sentient, and Unaffiliated

The formula by which enemy health scales is as follows:

${\displaystyle f_1(x) = 1 + 0.015(x - \text{Base Level})^2}$

When Current Level - Base Level < 70

${\displaystyle f_2(x) = 1 + \frac{24 \sqrt{5} }{5}(x - \text{Base Level})^{0.5}}$

When Current Level - Base Level > 80

Eximus

Eximus health scaling is the same across all factions

The formula by which eximus health scales is as follows:

${\displaystyle f_1(x) = 1 + 0.015(x - \text{Base Level})^2}$

When Current Level - Base Level < 70

${\displaystyle f_2(x) = 1 + \frac{24 \sqrt{5} }{5}(x - \text{Base Level})^{0.5}}$

When Current Level - Base Level > 80

In addition, the base health is also increased between certain breakpoints:

• Between level differences 0 inclusive and 15 inclusive, base health stays the same as listed in the Codex.
• Between level differences 15 exclusive and 25 inclusive, base health is linearly increased from +0% to +25% (e.g. for each level, enemy gains 2.5% base health).
• Between level differences 25 exclusive and 35 inclusive, base health is linearly increased from +25% to +150% (e.g. for each level, enemy gains 12.5% base health).
• Between level differences 35 exclusive and 50 inclusive, base health is linearly increased from +150% to +350% (e.g. for each level, enemy gains 13.33% base health).
• Between level differences 50 exclusive and 100 inclusive, base health is linearly increased from +350% to +500% (e.g. for each level, enemy gains 3% base health).
• Above level difference of 100, base health will stay +500% (6x) of its Codex value.

${\displaystyle {{\text{Health Multiplier}}={\begin{cases}f_{1}(x),\;&x\leq 15\\(1+0.025*(x-15))*f_{1}(x),\;&15<x\leq 25\\(1.25+0.125*(x-25))*f_{1}(x),\;&25<x\leq 35\\(2.5+2/15*(x-35))*f_{1}(x),\;&35<x\leq 50\\(4.5+0.03*(x-50))*[f_{1}(x)\times (1-S_{1}(x))+f_{2}(x)\times S_{1}(x)]\;&50<x\leq 100\\6*f_{2}(x),\;&100>x\\\end{cases}}}}$

Where the Health Multiplier is the value that multiplies an enemy's base health to its current health.

Enemy EHP

Effective Hit-points is a stat that indicates how much gross damage must be dealt to a target until the net damage thereby inflicted depletes its entire health pool. Effective Hit-points is not a fixed stat for any given enemy, it is heavily dependent on the damage type used against the target, as well as the various buffs and debuffs in effect for both the attacker and the enemy in question. For the following considerations, however, these influences are disregarded, as they do not alter the course of the graphs except for clinching or stretching them as a whole, which manifests as a scaling of the Y-axis.

For Enemies with Health only

For targets without shields and armor, the standardized effective hit-point scaling is synonymous with standardized health scaling, the health graph and formula apply.

For Enemies with Health and Shields

The standardized effective hit-points of shielded enemies are simply the sum of their shields and health, except for the case when the  Toxin damage portion of the gross damage depletes the target's health faster than the rest of the gross damage depletes its shield. Exact effective hit-point calculations considering damage types also become significantly more complex if  Toxin damage is involved, but this is disregarded here. The level scaling of standardized effective hit-points of shielded enemies is influenced by the ratio of base shields to base health:

${\displaystyle \text{EHP Multiplier} = \text{Health Multiplier} + \text{Shield Multiplier}\times\frac{\text{Base Shields}}{\text{Base Health}}}$

In the cases where you are trying to one-shot shielded enemies without  Toxin damage, their effective hit-points will actually be higher due to their shield gate mechanic. Only 5% of total damage dealt will only damage the enemy's health when their shield gate is active. However, attacking enemy weakpoints ignores the shield gate.

For Enemies with Health and Armor

The standardized effective hit-points of armored enemies are simply the health divided by the compliment of the damage reduction granted from armor. Because armor adds damage reduction to incoming damage on health the level scaling of standardized effective hit-points of armored enemies is influenced by the base armor itself:

${\displaystyle \text{EHP Multiplier} = \text{Health Multiplier}\times\left( 1 + \frac{\text{Base Armor}\times\text{Armor Multiplier}}{300} \right)}$

For Enemies with Health, Shields, and Armor

The standardized effective hit-points of enemies that are both armored and shielded are more complex than the simple EHP cases from the previous sections above. The level scaling of standardized effective hit-points of these enemies is influenced by the ratio of base shields to base health and base armor, making the formula at least 3 variable:

${\displaystyle \text{EHP Multiplier} = \text{Health Multiplier}\times\left( 1 + \frac{\text{Base Armor}\times\text{Armor Multiplier}}{300} \right) + \text{Shield Multiplier}\times\frac{\text{Base Shields}}{\text{Base Health}}}$
