World On Fire
Blast nearby foes with a burst of fire, and follow that up with a barrage of fireballs against any enemy who dares approach. Over time, these fireballs burn hotter as they consume more energy.

Initial Energy Drain: 3 s-1
Overheated Energy Drain: 6 s-1

Strength:250 / 300 / 350 / 400 (initial damage)
500 / 600 / 700 / 800 (overheated damage)
10% / 20% / 25% / 35% (status chance)
Range:7 / 10 / 12 / 15 m (initial radius)
3.5 / 5 / 6 / 7.5 m (overheated radius)
Misc:5 (number of targets)
6 s (overheat delay)
9.5 s (overheat buildup)

  • Ember ignites the environment, slamming her hand into the ground and dealing 250 / 300 / 350 / 400 Heat b Heat damage initially to a maximum of 5 enemies within an initial radius of 7 / 10 / 12 / 15 meters. Immediately after, Ember sustains wisps of burning flames in orbit around her, creating an aura that triggers a series of fiery explosions; each explosion inflicts 250 / 300 / 350 / 400 Heat b Heat damage to the same maximum number of enemies within a similar range. All instances of damage have a 10% / 20% / 25% / 35% status chance, while explosions occur at a rate of roughly 2 to 4.5 per second.
    • Damage and status chance are affected by Ability Strength.
    • Heat b Heat status effect deals 50% of World on Fire's base damage per tick over 7 ticks in 6 seconds. Ignited enemies will also panic and flail around for a brief period.
    • Initial radius is affected by Ability Range.
    • Enemies are prioritized upon World on Fire's activation. Higher priority will be given to enemies that pose the most immediate threat to Ember, such as enemies within close range.
    • Explosions will occur directly on enemies as long as they are within the initial radius.
    • With the exception of the initial explosions on activation, multiple explosions do not occur simultaneously.
  • After World on Fire remains active for 6 seconds, Ember's flames begin to overheat over the course of 9.5 seconds. As the flames overheat, damage per explosion gradually increases by 100% while the aura radius shrinks by 50% and energy drain per second increases by 100%.
    • Overheat percentage is displayed on the ability icon from 0% to 100%.
    • Overheat delay, buildup time, damage bonus, radius reduction, and energy drain rate penalty are not affected by mods.
  • World on Fire drains 3 energy per second, 6 at full percentage; it will remain active so long as Ember has energy. World on Fire will end if Ember runs out of energy or if deactivated; it can be reactivated by pressing the ability key (default 4 ).
  • Targets all types of enemies (e.g., mining machines, cameras, and turrets) excluding Void Laser Traps and Void Death Orbs.
  • Can be used while sliding and in the air.
  • World on Fire's visual after effects (debris) will appear gold when cast by Ember Prime.
  • Flame particle effects from wisps and explosions are affected by Ember's chosen Warframe energy color.
