Understand Flame Repellent
Useful when…
- Use when Heat Resistance is an intended defensive benefit for a Warframe setup.
Effect and slot
Flame Repellent is a standard Warframe mod with Vazarin polarity and base drain 4. It grants +10% Heat Resistance at rank 0, +40% at rank 3, and +60% at maximum rank 5. It cannot be equipped with Flawed Flame Repellent.
Rank progression and fusion costs
The listed fusion costs are 10 Endo and 483 Credits from rank 0 to 1, 40 Endo and 1,932 Credits from rank 2 to 3, and 160 Endo and 7,728 Credits from rank 4 to 5. The known effects show +40% at rank 3 and +60% at rank 5; rank 4's effect is not specified.
Related defensive choices
Flawed Flame Repellent is a lower-rank, lower-drain version that reaches +20% Heat Resistance at rank 3, and it cannot be equipped together with Flame Repellent. Adaptation grants +10% resistance to the damage type that hits the Warframe for 20 seconds per stack, up to 90%, so its conditional stacking effect differs from Flame Repellent's stated Heat Resistance. Adept Surge is a Conclave Exilus mod with +10% Mobility and -25 Health, not a Heat-resistance substitute.
Acquisition sources
Listed sources include Ancient Healer, Ancient Protector, Flameblade variants, Mutalist Moa variants, Tusk Predator, and Thermic Raknoid. The listed chance is 0.76% for the named sources other than Thermic Raknoid, which is listed at 3.79%.
Limitations and tradeoffs
- The effect is limited to Heat Resistance, so its value depends on the damage a build needs to withstand.
- It uses a standard Warframe mod slot and cannot be equipped with Flawed Flame Repellent.
Common mistakes to avoid
- Treating Heat Resistance as resistance to every damage type.
- Trying to equip Flame Repellent together with Flawed Flame Repellent.
