Damage/Heat Damage

Fire damage is one of the core 4 elemental damages (ones that you can mod onto your weapon). It is extremely strong against Infested, having a x2 multiplier to all light units.

Unlike many other games with Fire damage, in Warframe it does no additional damage over time, but rather another flat bonus. Corpus Crewman, Grineer, and Infested enemies hit by fire damage have a high chance to either break out of cover or stop moving to try and put out the flames, similar to a knockback. In both instances, this makes them more vulnerable to additional damage from ranged weapons, or consecutive melee strikes.
