Quick Thinking is a mod that uses the Warframe's residual energy pool as an emergency buffer to prevent death whenever a player drops to 2 Health.

Notes

• Stacks with  Gladiator Finesse for a total of 300% efficiency.
• The Warframe's Armor and any sources of damage reduction will still reduce incoming damage and as such, the amount of energy drain.
• While under the effects of Quick Thinking (2 HP and losing energy instead), strong hits will cause the Warframe to stagger. Be wary, as repeated strong hits can effectively stun-lock you in place until you die. Weak hits will not induce this effect.
  •  Pain Threshold drastically reduces the stagger duration, allowing one to avoid being stun-locked.
  • A max rank  Primed Sure Footed will completetly remove the stagger.
• Damage taken while Quick Thinking is in effect does not count as taking Health damage; as such,  Rage and  Hunter Adrenaline do not convert incoming damage into energy, and  Vex Armor and  Vexing Retaliation do not trigger their effects.
• Quick Thinking has the lowest priority of all death prevention effects, such as  Nidus' or  Wukong's passives or  Phoenix Renewal. Only after all other means of preventing lethal damage are exhausted, Quick Thinking will start draining energy.
• If a single attack is sufficiently strong enough to kill in one strike (i.e. damage value in excess of the total available health after armor damage reduction, plus the possible energy-converted buffer), the player will instead enter bleedout immediately and not lose any energy. This is to avoid wasting energy, as the player would've been killed regardless.
• Ability Efficiency has no effect on the amount of energy lost while under the effects of Quick Thinking.
• Due to Hildryn's unique mechanic of using her shields to power her abilities instead of having an energy pool, this type of mod does not work with Hildryn.

Tips

• Using  Flow or  Primed Flow is more or less a necessity to take full advantage of Quick Thinking.
• Using Zenurik school's Void Dash upgrade Energizing Dash is very useful for keeping your energy and thus your effective health up.
•  Energy Siphon aura can also help regain lost energy.
• This mod is a good defense against damage that bypasses shields such as damage, which can take down a player by surprise.
• Quick Thinking works exceptionally well with  Trinity, as she can spam  Energy Vampire for an endless supply of energy.
•  Desecrate helps recover health and energy orbs, and the mod itself works well with  Nekros because of this. 
• This mod also works well with  Limbo due to the Rift Plane's ability to restore energy, as well as his increased energy pool. 
• Magnetic procs, such as those from an Ancient Disruptor or Sensor Bar, will instantly drain energy to 0 for several seconds, rendering this mod useless during that time. Also,  Rage and  Hunter Adrenaline will not replenish energy if a portion of health is lost during a Magnetic proc.  

Trivia

• Prior to Update 11.1 (2013-11-27), it could be combined with  Rage, to convert energy to health for your Warframe many times in a row with 96% efficiency.

Patch History

Update 21.3 (2017-08-02)

• Reduced the frequency that Quick Thinking can stagger lock a player. This is actually undoing a bug fix where Quick Thinking wasn't staggering players as often as it was intended to, but this is the new intention now! Essentially Quick Thinking is back to the way it was pre Update 21.

Update 17.10 (2015-11-04)

• Fixed the Quick Thinking Mod not properly taking damage reduction into account before removing energy from a Client.

Hotfix 14.6.1 (2014-09-11)

• The 14.6.0 fix resolves issues where Rage + Quick Thinking gave effective permanent invulnerability because energy was being added to pool that was never dealt to player. With this change in mind, the combination of Rage and Quick Thinking may seem less efficient as before due to no longer giving effective invulnerability. The scope of this change is being monitored to ensure the usefulness of these Mods as a combination.

Hotfix 14.0.8 (2014-07-24)

• Fixed Quick Thinking not working as described or intended.

Update 11.6 (2014-01-08)

• Increased stagger threshold and made stagger only occur on big hits instead of on accumulated damage; this should prevent situations where Quick Thinking would save you only to let you get knocked down and killed again.

Update 11.1 (2013-11-27)

• Reduced effectiveness of the interaction between Rage/Quick Thinking mods to prevent indefinite immortality in all game modes.
• The Quick Thinking mod no longer saves you from suicide damage.

Update 10.3 (2013-10-09)

• Added missing mod card image for Quick Thinking.
