=== Weapon List ===
The '''Firebug''' is the flame-spewing maniac that keeps the Zed horde from overrunning your squad. Armed with a variety of fire-producing weapons, the Firebug can put large groups of Zeds in a panic by keeping them burning until they are little more than cinders. While Firebugs often score fewer Zed kills than other perks, they instead usually lead in assists as they hose down large numbers of Zeds with their gouts of problem-solving fire.

=== Bonus Experience ===
<div class="toclimit-3">__TOC__</div>
The Firebug is awarded bonus experience for killing Crawlers with Perk weapons.
 
{|class="wikitable" style="text-align: center; background-color: #E5EECC;"
==General Information==
!
 
! scope="col" | Normal
Being a flame weapons specialist, the Firebug sets multiple ZEDs on fire at time, making them suffer from the [[Mechanics_(Killing_Floor_2)#Gameplay_-_Damage_over_time_.28DOT.29|damage over time]], stumbling and forcing them to panic which effectively decreases overall threat of the enemy crowd. Flame weapons of the Firebug provide a [[Mechanics_(Killing_Floor_2)#Weapons_-_Fire_.2F_flame_weapons|wide variety]] of ways to apply the damage.
! scope="col" | Hard
 
! scope="col" | Suicidal
Firebug skill choices let them focus on either killing ZEDs faster via improved flame damage and afterburn or on controlling the ZEDs flow through the various [[Mechanics_(Killing_Floor_2)#Gameplay_-_Afflictions|incapacitations]] methods.

=== Skill utilisation ===
===Perk Notes===
 
* Damage modification (passive + skills): Passive damage bonus, ''Bring the Heat'' skill and ''Inferno'' skill affecting damage of all on-perk weapons (including Knife) or on-perk damage types. Damage ROUNDED.
* Skill (Barbecue): ''Barbecue'' increases DOT duration by x2.5 times. This skill stack with the ''Napalm'' skill for total of x5 longer DOT duration.
* Skill (Firestorm): [[Caulk_n%27_Burn|Caulk n' Burn]], [[Flamethrower_(Killing_Floor_2)|Flamethrower]] and [[Microwave Gun]] change their flame / beam model to another model that is approximately x1.4 times extensive.
* Skill (Ground Fire): Skill does not work with the Residual Flames. Calculation specifics: skill mutiplies DEFAULT Ground Fire damage value by 2 and adds this value to PERK AFFECTED Ground Fire damage value. Example: Bloat (neutral to fire) vs lvl 25 + Ground Fire. Bring the Heat OFF: Damage = (10x1.2) + (10x2) = 32. Bring the Heat ON: Damage = (10x1.55) + (10x2) = 36.
* Skill (Heat Wave): Skill forces ZEDs to stumble as long as they are not in cooldown and can do such special move. Effective radius - 3 meters.
* Skill (Napalm): Initial damage - 7, DOT duration - 5s x3.5 (boosted by the skill itself), DOT interval - 1s, DOT damage scale, of initial damage - x0.4. When ZED is being attacked by the player with the flame-spraying weapon there happening AOE check around this ZED (check interval - 0.25s, check radius is twice as wider (x2) than ZED's collision cylinder). All the other ZEDs within this radius take napalm damage and become "napalm infected" for the duration of DOT. "Infected" status prevents them from taking / spreading napalm damage to other ZEDs. When this status gets worn off it is become possible to cause another AOE check by attacking these ZEDs. Unlike surrounding ZEDs, initial target is almost never gets marked as "infected" hence always take Napalm damage. ZEDs also spread napalm upon bumping into each other.
* Skill (Napalm and Barbecue interaction): Due to calculation specifics both skills provide total DOT duration multiplier of x5, however when selected alone Napalm provides DOT duration multiplier of x3.5 while Barbecue alone increases DOT duration only by x2.5.
* Skill (ZED Shrapnel): Explosion can be activated by all on-perk weapons or on-perk damage types. Chance - 20%, damage - 10, radius - 2 meters, falloff - linear, knockdown / melee hit / stumble power - 500.
 
===On-perk Weapons===
 
Following weapons and damage types are associated with the Firebug. They are getting damage bonuses and buffs to their attributes from the respective skills:
 
Beam_Microwave
 
Flame_CaulkBurn
 
Flame_Flamethrower
 
HuskCannon
 
Knife_Firebug
 
MolotovGrenade
 
MolotovSplash
 
Pistol_Flare, Pistol_DualFlare
 
Shotgun_DragonsBreath
 
SMG_Mac10
----
Ballistic_DragonsBreath
 
Explosive_HuskCannon
 
Explosive_Shrapnel
 
Fire
 
Fire_FlareGun, Fire_FlareGun_Dual (child of Ballistic_Handgun)
 
Fire_FlareGunDoT


Initial skill selection for the Firebug is fairly straightforward. Fully Stocked is beneficial in the early part of each game, granting full ammunition when spawning with the Caulk'n'Burn, and upon the purchase of any new weapon in the Firebug sphere. Once the player has bought all their preferred weapons for this perk, it's no longer required to opt for Fully Stocked, and instead beneficial to switch to Flaratov Cocktail. This skill grants a longer burn time for the Firebug's perk grenade, a weapon which is highly effective at causing the affliction "Fire Panic".
Fire_Mac10 (child of Ballistic_Shotgun), Fire_Mac10DoT


Level 10's skills present another easily deduced choice. Although Fuse might be beneficial in situations where the enemies aren't fast enough to close in on the player, the higher up the difficulty levels a player progresses, the more likely they are to find less damage-over-time benefit from Fuse due to the increasing speed of enemies. Additionally, the generally short range of all Firebug weapons inhibits effective use of Fuse with three of the four base weapons, trench gun excluded - however, the fairly limited ammunition supply of the trench gun doesn't warrant opting for Fuse under most circumstances. Heat Wave, on the other hand, attaches the ability to cause the affliction "Stumble" to any enemy that isn't already on a stumble cooldown. Particularly regarding trash zeds, Heat Wave has a great deal of utility to it, allowing the player to keep most enemies from harming them whilst said enemies continue to take burn damage.
HuskCannonDot (child of Fire)


Level 15 is yet another lop-sided choice between Zed Shrapnel and Zed Napalm. Zed Napalm causes zeds that come into contact with already burning zeds, to catch fire also and take damage. The damage that is transferred though is limited and of little value. Zed Shrapnel conveys a 30% chance for a killed zed to explode and damage other enemies, making this skill choice exponentially more effective, particularly against groups of enemies. Additionally, the damage type of Zed Shrapnel is explosive, meaning that sirens will take 2x the actual damage caused by Zed Shrapnel, relative to their range from the explosion.
Microwave_Beam, Microwave_Blast


Level 20 presents a mostly straightforward choice also, depending on the weapons used. Because the Flamethrower has higher impact damage than the Caulk'n'burn, the Range skill [which boosts range of applicable weapons by 50%] is beneficial in keeping enemies at bay. The Splash Damage skill doubles the splash damage of all Firebug weapons [trench gun excluded] which is arguably more beneficial for the Caulk'n'Burn/Microwave Gun loadout. Considering that ground-fire statistics are effectively the same for the Flamethrower and the Caulk'n'Burn, the Range skill grants more benefits for directly burning enemies with either weapon rather than setting fire to the ground.
==Strategy==


Level 25 has arguably limited benefits either way. Regarding Combustion, unless a high-level Commando is frequently chaining kills to extend zed-time, it's not guaranteed for a Firebug to be able to kill an enemy in the time it takes for zed-time to finish. Despite this, it's arguably a more effective choice than Scorch, which merely alters fire-time to be ~90% of real-time rates of fire.
Due to the natural resistance to fire, Scrakes and Fleshpounds should be the lowest priority for Firebugs. Instead focus on killing small ZEDs and clearing escape routes as your team will likely fall back upon engaging the big ones.


=== Weapons and team strategy ===
Conserve your ammo by using [[Mechanics_(Killing_Floor_2)#Weapons_-_Flame_tracing_.2F_post-firing|tap-firing]] tactics.


In order to understand how best to use this perk, it's important to understand the function of the weapons, the skills, the afflictions these can cause and how these combine to create particular beneficial circumstances for the team.
[[Mechanics_(Killing_Floor_2)#Weapons_-_Fire_.2F_flame_weapons|Learn your weapons]] - despite the plain notion of how flame weapons should be utilized, they actually offering a wide choice of ways to deal the damage including afterburn, ground fire and splash damage.


The starting weapon is the Caulk'n'Burn. For lower level Firebugs [less than level 10] this weapon will be tricky to use effectively without taking much damage. The Heat Wave skill grants the ability for any Fire weapon to cause the affliction "Stumble" when the zed is within a short distance of the player, vastly improving the effectiveness of the starting weapon. This affliction operates on a cooldown depending on the enemy that suffers the affliction; clot variants can be stumbled almost at will, gorefasts can only be stumbled once every 2 seconds, scrakes can be stumbled once every eight seconds, and fleshpounds only once every 10 seconds, regardless of which Fire weapon is used in conjunction with the Heat Wave skill. The Caulk'n'Burn is highly effective against trash zeds from wave 1 to 10, regardless of the difficulty - assuming the player has access to, and uses, the Heat Wave skill.
If your teammate is in trouble save them a second of two by utilizing your special ability to stumble ZEDs via ''Heat Wave'' skill - it can even stumble an enraged Fleshpound!


The tier-2 weapon is the Incendiary Trench Gun. This weapon has a maximum capacity of 46 rounds, has a penetration power of 2, and is able to create an affliction called "Fire Panic". Other Fire weapons can create this affliction, granted, however the Incendiary Trench Gun is the weapon that is most effective at doing so. Somewhat vexing to Firebugs is the Husk - this enemy has relatively high HP, and causes problems to Firebugs due to its inherent 50% resistance to fire type attacks. The Incendiary Trench Gun can be a solution to this problem in that the ballistic damage is capable of decapitating the Husk with a single point-blank shotgun blast. This is effective on all difficulties excluding Suicidal at >4 players, and Hell on Earth difficulty at >2 players for a level 25 Firebug. Bear in mind that there is only a small amount of head HP remaining after a point-blank shotgun blast to a Husk, and that a small number of 9mm shots can precede or follow this attack. Whilst the Incendiary Trench Gun is often regarded as being a sub-par weapon, its ability to cause the Fire Panic affliction, inflict ballistic damage to Husks and penetrate more than one trash zed with each shell, provides a greater degree of utility to the Firebug than it is generally regarded as having.
Even if your weapons are not as much effective against [[Husk_(Killing_Floor_2)|Husks]] as many others, you still might want to focus on killing that ZED. Your fire resistance ability and [[Incendiary Trench Gun]] will aid you in this mission.


The Flamethrower is a highly effective but often overlooked weapon. Both the Flamethrower and the Caulk'n'Burn generally use 4 units of ammunition per "burst". However, the Flamethrower's total ammunition capacity is 33% higher than the Caulk'n'Burn, each "magazine" is twice the size of the Caulk'n'Burn, and the impact damage itself from the Flamethrower has a base level of 25 against the Caulk'n'Burn's 10. In all, the Flamethrower is a superior weapon, boasting substantial benefits that outperform the 2 extra weight carried. Using the Range skill with the Flamethrower allows the Firebug to keep most trash zeds under control almost indefinitely if the ammunition is used diligently. The one problem that arises in the minds of most players is that the use of the Flamethrower precludes the use of the Microwave Gun - the tier 4 weapon for Firebugs.
Your [[Molotov_Cocktail|Molotovs]] not only set ZEDs on fire but also spawn a light emitting flare that lasts for roughly 30 seconds. Very helpful if you play on dark maps like [[Catacombs]].


The Microwave Gun is a peculiar weapon to the Firebug. This weapon operates on the Microwave damage type, rather than specifically Fire type. This weapon is best used directly against an enemy's body at lower levels, and best used when pointed at the ground close to an enemy at higher levels when using the Splash Damage skill. In all instances, however, it is beneficial to tap-fire the weapon as the damage continues for a short period of time after the weapon has stopped firing. This tactic of tap-firing with short gaps in between allows for less ammunition consumed for effectively the same result. The splash damage of the Microwave Gun has a fairly large radius, meaning that aiming at the ground at a particular enemy's feet will still damage other enemies inside that attack's area-of-effect. This is especially effective for dealing with large groups of weaker enemies, with the bonus of not requiring the player to aim precisely in order to achieve good results. Microwave damage is 2x effective against scrakes. However, as the player moves up the difficulty levels, scrakes have substantially larger health pools - this makes the 2x bonus against scrakes progressively less and less effective. Considering the amount of ammunition required to kill a scrake on Hell on Earth, 6-player HP values, a player might only have enough ammunition to dispatch approximately 5 scrakes in a wave. This excessive use of Microwave Gun ammunition renders the Firebug less effective in clearing trash zeds, which is the most efficient and productive use of its ammunition.
===Perk Utilization===


The Firebug does well to understand how important their role really is. Although being the most efficient and effective killer of trash zeds in the game isn't the most glorious of roles, it is arguably the most important. As such, Firebugs that forgo the short-term glory of attacking scrakes, will dramatically increase their team's chances of survival by dealing with the more numerous and dangerous-in-numbers weaker enemies. Firebugs that possess a degree of lateral thinking and forethought will consistently be able to keep trash zeds away from the team's position, simply by circumventing scrakes and fleshpounds, and concentrating on the other, weaker, enemies.

Two common loadouts will be centred around the level 20 skills - Range and Splash Damage. Splash Damage offers considerable benefits for players opting for the Caulk'n'Burn/Microwave Gun loadout. Range on the other hand, is arguably more beneficial for the Flamethrower, as this weapon's splash damage value and radius is no better than that of the Caulk'n'Burn. Flamethrower loadouts with either the Caulk'n'Burn or the Incendiary Trench Gun allow 1 spare unit of weight for use of the HMTech-101 Pistol: a helpful addition to the arsenal of any team-oriented player. Its capacity to heal other players at range, and its base damage of 20 - which can decapitate most trash zeds in one shot - cannot be underestimated.
By contrast, if the team has decided that they will kill Scrakes and Fleshpounds by decapitation, then Firebugs do well to observe this team idea by avoiding big ZEDs entirely. Because flame weapons cause body HP damage almost exclusively, most attacks upon Scrakes / Fleshpounds with flame weapons will not assist in achieving a decapitation due to the difference in head and body HP pools. In actuality, using flame weapons to attack big ZEDs that result in "Fire Panic" and "Stumble" [[Mechanics_(Killing_Floor_2)#Gameplay_-_Afflictions|afflcitions]], will negatively impact a team's ability to smoothly decapite them. As such, it is important for the team to discuss their intentions and make their roles clear so that the chances of survival for all players on the team is maximised.


If the team has decided that body damage to scrakes is the method they will choose to kill them, then the Firebug does well to cause the "Fire Panic" and "Stumble" afflictions previously mentioned. For Firebugs not using the Incendiary Trench Gun, Fire Panic can still be achieved by using the Molotov perk grenade. These afflictions are capable of causing incapacitation to scrakes [particularly when used in succession] for periods long enough to kill them outright.

The Firebug is the flame-spewing maniac that keeps the Zed horde from overrunning your squad. Armed with a variety of fire-producing weapons, the Firebug can put large groups of Zeds in a panic by keeping them burning until they are little more than cinders. While Firebugs often score fewer Zed kills than other perks, they instead usually lead in assists as they hose down large numbers of Zeds with their gouts of problem-solving fire.

General Information

Being a flame weapons specialist, the Firebug sets multiple ZEDs on fire at time, making them suffer from the damage over time, stumbling and forcing them to panic which effectively decreases overall threat of the enemy crowd. Flame weapons of the Firebug provide a wide variety of ways to apply the damage.

Firebug skill choices let them focus on either killing ZEDs faster via improved flame damage and afterburn or on controlling the ZEDs flow through the various incapacitations methods.

Perk Notes

  • Damage modification (passive + skills): Passive damage bonus, Bring the Heat skill and Inferno skill affecting damage of all on-perk weapons (including Knife) or on-perk damage types. Damage ROUNDED.
  • Skill (Barbecue): Barbecue increases DOT duration by x2.5 times. This skill stack with the Napalm skill for total of x5 longer DOT duration.
  • Skill (Firestorm): Caulk n' Burn, Flamethrower and Microwave Gun change their flame / beam model to another model that is approximately x1.4 times extensive.
  • Skill (Ground Fire): Skill does not work with the Residual Flames. Calculation specifics: skill mutiplies DEFAULT Ground Fire damage value by 2 and adds this value to PERK AFFECTED Ground Fire damage value. Example: Bloat (neutral to fire) vs lvl 25 + Ground Fire. Bring the Heat OFF: Damage = (10x1.2) + (10x2) = 32. Bring the Heat ON: Damage = (10x1.55) + (10x2) = 36.
  • Skill (Heat Wave): Skill forces ZEDs to stumble as long as they are not in cooldown and can do such special move. Effective radius - 3 meters.
  • Skill (Napalm): Initial damage - 7, DOT duration - 5s x3.5 (boosted by the skill itself), DOT interval - 1s, DOT damage scale, of initial damage - x0.4. When ZED is being attacked by the player with the flame-spraying weapon there happening AOE check around this ZED (check interval - 0.25s, check radius is twice as wider (x2) than ZED's collision cylinder). All the other ZEDs within this radius take napalm damage and become "napalm infected" for the duration of DOT. "Infected" status prevents them from taking / spreading napalm damage to other ZEDs. When this status gets worn off it is become possible to cause another AOE check by attacking these ZEDs. Unlike surrounding ZEDs, initial target is almost never gets marked as "infected" hence always take Napalm damage. ZEDs also spread napalm upon bumping into each other.
  • Skill (Napalm and Barbecue interaction): Due to calculation specifics both skills provide total DOT duration multiplier of x5, however when selected alone Napalm provides DOT duration multiplier of x3.5 while Barbecue alone increases DOT duration only by x2.5.
  • Skill (ZED Shrapnel): Explosion can be activated by all on-perk weapons or on-perk damage types. Chance - 20%, damage - 10, radius - 2 meters, falloff - linear, knockdown / melee hit / stumble power - 500.

Strategy

Due to the natural resistance to fire, Scrakes and Fleshpounds should be the lowest priority for Firebugs. Instead focus on killing small ZEDs and clearing escape routes as your team will likely fall back upon engaging the big ones.

Conserve your ammo by using tap-firing tactics.

Learn your weapons - despite the plain notion of how flame weapons should be utilized, they actually offering a wide choice of ways to deal the damage including afterburn, ground fire and splash damage.

If your teammate is in trouble save them a second of two by utilizing your special ability to stumble ZEDs via Heat Wave skill - it can even stumble an enraged Fleshpound!

Even if your weapons are not as much effective against Husks as many others, you still might want to focus on killing that ZED. Your fire resistance ability and Incendiary Trench Gun will aid you in this mission.

Your Molotovs not only set ZEDs on fire but also spawn a light emitting flare that lasts for roughly 30 seconds. Very helpful if you play on dark maps like Catacombs.

As such, it is important for the team to discuss their intentions and make their roles clear so that the chances of survival for all players on the team is maximised.
