Team Fortress 2/Pyro

The Pyro is specialises in close quarters combat, dealing out damage rapidly with his flamethrowers. He can also inflict afterburn, which will weaken and kill enemies that manage to escape. The Pyro is deadly when flanking and ambushing. His flames can cause panic and confusion if caught by surprise with it. Outside of that, his air blast ability is a great support and defensive tool. With it, he can deflect projectiles, push enemies away, extinguish flaming teammates and even stall Ubers. Whether if used for deadly ambushes or for supporting the team, the Pyro performs his job greatly.

Weapons
The Pyro is mostly designed for close range combat, though he does have secondaries to help him at longer ranges. His melee weapons are also great for finishing off enemies at point blank. Flamethrowers with cheap airblasts are suitable for any situation, though the Backburner and the Phlogistinator's crits are deadly when flanking large groups.

Flamethrower/Rainblower
The Flamethrower is a very powerful weapon, but has a very short range. The Flamethrower shoots out lots of particles that does tiny damage which racks up due to the amount of particles. The particles lag behind the visible flames rendered in a server. When you hit a player with any one of the particles they will be set on fire and take a further 60 damage over 10 seconds. A common strategy is to set your opponent on fire and run, leaving your enemy to die by the flames. Keep in mind that your chances of succeeding will be much higher if you catch your enemy off guard, if the enemy knows you're coming you will likely fail. Disguised spies will be set on fire if you flame them. A good way to spy-check is to puff some fire into your teammates. If you do set a "teammate" on fire it is a disguised spy, you should proceed to bake him.
 * Ammunition: 200
 * Point Blank Damage: 6.82 per particle (~153.45 DPS)
 * Medium Range Damage: 4.09 per particle (~92.07 DPS)
 * Afterburn Damage: 60 over 10 seconds
 * Critical Hit: 12-21 per particle (~276.21-460.35 DPS)
 * Armageddon Damage: 400 (Decreases by half for each subsequent target)
 * Armageddon Duration: 5

The flamethrower cannot fire underwater, however, holding down your jump key (default spacebar) will allow you to skim across the top and fire into the water.

The flamethrower's alternate fire will let out a burst of compressed air at the cost of 20 ammo. This burst of air can reflect projectiles, extinguish teammates, shift stickies and bounce enemy players around. Airblasted projectiles become critical hits when returned to the enemy. Keep in mind when reflecting projectiles that the airblast isn't simply a mirror: Rockets, grenades, midair stickies and flares will all be redirected to where your crosshair is pointing. You can use it on ubered people too, try and separate the enemy medic from his patient or just bounce both enemies away until the uber wears off. It can also be useful to stop enemies like scouts from running away: Airblast them into the air to buy you some time to get in between them and wherever they're trying to go. Whenever you see a teammate on fire who isn't likely to head back to resupply, put him out with your airblast.

The Rainblower reskin not only automatically puts you in Pyroland vision, it also has its own taunt kill called Armageddon. When activated, you will create a rainbow above you (spew fire out of your mouth) and generate a massive fireball that damages and ignites nearby enemies. The damage is relatively low for a taunt kill, but its area is wide enough to hit multiple enemies nearby.

Backburner
The Backburner is the unlockable Flamethrower designed for ambushing. It inflicts crits when burning an enemy from behind, but air blasting requires 50 ammo instead of 20.
 * Ammunition: 200
 * Point Blank Damage: 6.82 per particle (~153.45 DPS)
 * Medium Range Damage: 4.09 per particle (~92.07 DPS)
 * Afterburn Damage: 60 over 10 seconds
 * Critical Hit: 12-21 per particle (~260.21-460.35 DPS)

The crits from behind means you get much more with an ambush. While the Flamethrower is good for 1-on-1 confrontations, the Backburner can devestate most of the enemy team if caught by surprise. Your airblasts cost much more ammo, and can quickly run out, so save it only for emergency situations, and don't directly engage Soldiers.

Degreaser
The Degreaser grants you a faster switch time between weapons, but direct damage and afterburn damage is reduced.
 * Ammunition: 200
 * Point Blank Damage: 6.14 per particle (~138.15 DPS)
 * Medium Range Damage: 3.68 per particle (~82.8 DPS)
 * Afterburn Damage: 40 over 10 seconds
 * Critical Hit: 11-18 per particle (~248.4-414.45 DPS)

The Degreaser isn't as good as your other flamethrowers on it's own, but combined with the right weapons, it can become a deadly tool in your arsenal. Set alight an enemy, airblast if you need to then quickly switch to your Axtinguisher or Flare Gun and you can finish them before they even realize what has happened. You will be at a slight disadvantage against other Pyros as you have to rely on your other weapons to outdamage them.

Phlogistinator
The Phlogistinator lacks the ability to airblast or deal random crits and has a 10% damage penalty. It does have a unique meter called Mmmph. Any fire damage wil fill up the mmmph meter, and when it's full pressing the alt-fire button will make the Pyro taunt and activate the mmmph buff. During the taunt the Pyro receives a 75% resistance to damage. For ten seconds after activation you'll be fully-healed and get unlimited crits.
 * Ammunition: 200
 * Point Blank Damage: 6.14 per particle (~138.15 DPS)
 * Medium Range Damage: 3.68 per particle (~82.8 DPS)
 * Afterburn Damage: 40 over 10 seconds
 * Critical Hit: 11-18 per particle (~248.4-414.45 DPS)
 * Buff Effect: Refills health completely and unlimited crits
 * Damage Dealt for Effect: 221 fire damage
 * Effect Duration: 10 seconds

The Phlogistinator requires the user to employ similar tactics when using the Backburner due to the lack of airblasts. You must use ambush techniques to take down opponents, and live long enough to fill your Mmmph meter. You can also use other forms of fire damage like the Flare Gun to build meter. Once it's full, try to save it until you come across a large group of enemies and unleash it. With the crits you can quickly take out an entire team without having to worry about your health.

Shotgun
The shotgun is the Pyro's standard ranged weapon. The shotgun is an incredibly useful weapon for the pyro, good for finishing off burning enemies, dealing damage while running away from combat, dealing damage while running towards combat and fighting underwater. You should be using the shotgun almost as much as the flamethrower.
 * Clip Size: 6 - Reserve Ammo: 32
 * Point Blank Damage: 86-90
 * Medium Range Damage: 24-67
 * Long Range Damage: 3-26
 * Critical Hit: 120
 * Hadouken Duration: 3 seconds
 * Hadouken Damage: 500

All your secondary weapons except the Scorch Shot give you the Hadouken taunt kill. The Pyro will cup his hands together then let's out a short burst of energy that will instantly kill any enemy hit by it. The taunt is too slow to be viable as a killing tool, but it can be a good humiliation kill.

Flaregun
The unlockable alternative to the shotgun. While this gun does little direct damage, it sets people on fire, making it perfect for long range harassing. Snipers in particular can't aim properly while on fire, so one of your greatest weaknesses, long range, can be somewhat negated by good use of this gun.
 * Clip Size: 1 - Reserve Ammo: 16
 * Base Damage: 30
 * Afterburn Damage: 60 over 10 seconds
 * Critical Hit: 90
 * Hadouken Duration: 3 seconds
 * Hadouken Damage: 500

In addition, the flaregun scores critical hits on targets that are already on fire, dealing 90 damage. While this doesn't sound like a lot, it is just enough to guarantee that a 125 HP class will die in 2 flares launched one after the other (30 for the first flare + 90 for the second + afterburn damage = 120+). Repeated, accurate hits will quickly whittle away enemy health.

Detonator
The Detonator is pretty much similar to the Flare Gun, except that you can detonate your flares by right-clicking, igniting enemies nearby. The downside to that is that you will only inflict mini-crits to burning enemies, as well as doing more damage to yourself if you're caught in the blast.
 * Clip Size: 1 - Reserve Ammo: 16
 * Base Damage: 30
 * Afterburn Damage: 60 over 10 seconds
 * Detonation Damage: 10-20
 * Flare Explosion: 56
 * Self-Damage: 39-68
 * Critical Hit: 90
 * Hadouken Duration: 3 seconds
 * Hadouken Damage: 500

The strategy for the Detonator is pretty similar with the Flare Gun. It's detonation feature negates the difficulty of aiming the flare. You can also detonate flares at your feet to perform a flare jump, a rather weak counterpart to the rocket jump, which is useful for getting onto ledges just out of reach and to place yourself in unusual ambush positions.

Reserve Shooter
The Reserve Shooter let's you switch weapons faster (but slower than the Degreaser), and deal mini-crits to airborne enemies within a few seconds after taking it out. However, it only has 3 shells a clip.
 * Clip Size: 3 - Reserve Ammo: 32
 * Point Blank Damage: 86-90
 * Medium Range Damage: 24-67
 * Long Range Damage: 3-26
 * Critical Hit: 120
 * Hadouken Duration: 3 seconds
 * Hadouken Damage: 500

The Reserve Shooter is deadly powerful with the Pyro's air blast. Air blasting an enemy into the air and emptying a clip into them will leave them with little health left, if not straight up kill them. Degreaser coupled with this weapon makes the switch time ridiculously fast, but you can also use another flamethrower for better damage.

Manmelter
The Manmelter fires energy bolts similar to flares. These shots travel 50% faster and cannot be deflected by airblasts, but cannot inflict random critical hits. The gun itself does not require ammo or reload, though there is a cooldown period between shots. Holding alt-fire with it let's you suck up flames and extinguish teammates, which will give you one guaranteed crit for every teammate extinguished.
 * Clip Size: 1 - Reserve Ammo: Infinite
 * Base Damage: 30
 * Afterburn Damage: 60 over 10 seconds
 * Critical Hit: 90
 * Hadouken Duration: 3 seconds
 * Hadouken Damage: 500

The Manmelter's projectiles are much easier to land than normal flares, due to the increased speed. The alt-fire is a cheaper way of extinguishing teammates as it uses no ammo, and works well with the Backburner or the Phlogistinator which have limited or no airblasts to use. The stored crits combined with the faster projectile speed can take down an enemy much quicker, possibly even better than connecting a Flare Gun shot on a burning enemy.

Scorch Shot
The Scorch Shot only deals half the damage of your other flare guns, but its flare is unique in that it will knock players back and ignite nearby enemies on a successful hit. The knockback will be stronger the further your target is from you. It can also be used to destroy stickies.
 * Clip Size: 1 - Reserve Ammo: 16
 * Base Damage: 15
 * Afterburn Damage: 60 over 10 seconds
 * Critical Hit: 45
 * Execution Duration: 3 seconds
 * Execution Damage: 400

The Scorch Shot is a bit like a long-distance flamethrower. You get to ignite a group of enemies with one shot and knock your main target back similar to an airblast, which can throw them off cliffs. It is especially good against a Medic and his patient, as you're bound to ignite both with a single flare due to the nature of the projectile. You can also push Ubered foes back from a safe distance.

Fire Axe/Frying Pan/Saxxy/Conscientious Objector/Freedom Staff/Bat Outta Hell/Memory Maker/Lollichop
The Fire Axe is often outperformed by your Flamethrower, as it is much better for close range. It is an alternative weapon when you're underwater. It is also good for flanking, since enemies will usually regard axe hits as merely stray bullets, until you ignite them with the Flamethrower. The Fire Axe is also better against enemy Pyros than the Axtinguisher, since you can't light them on fire.
 * Attack Interval: 0.8 seconds
 * Normal Damage: 65
 * Critical Hit: 195

Note that the Lollichop will automatically give you Pyroland vision and has a different taunt animation, though these changes are entirely aesthetic.

Axtinguisher/Postal Pummeler
The Axtinguisher is the alternative fireaxe. It does half damage normally, it always crits against flaming enemies. It also doesn't randomly crit. This makes it a superior choice in many situations, but if you take the flaregun and this weapon you will barely be able to fight underwater at all.
 * Attack Interval: 0.8 seconds
 * Normal Damage: 33
 * Critical Hit: 195

This weapon is quite useful for flanking, as enemies usually do not have enough time to return damage if you catch them by surprise. An effective technique is the Puff n'Sting, in which one ignites the enemy, airblasts them into a wall then hit with the axe. This will usually disorient players until the lethal blow.

Homewrecker/Maul
The Homewrecker does more damage to buildings and destroys sappers in one hit, but does less damage against other players. It can destroy any buildings at full health in two hits, as well as one-shot Combat Mini Sentry Guns.
 * Attack Interval: 0.8 seconds
 * Player Damage: 42-55
 * Building Damage: 130
 * Critical Hit: 147

The Homewrecker makes you an even better Spy counter. Staying near an Engineer base can make it almost impossible for Spies to take down. You can easily ignite any disguised Spy and destroy any sappers they placed faster than an Engineer. As for destroying buildings, you should mostly go for unattended Dispensers or Teleporters away from the Engineer or a Sentry Gun. Assuming the Engineer is taken down and you manage to sneak up to a Sentry, you can circle-strafe the sentry gun while whacking it to avoid taking damage.

Powerjack
The Powerjack heals you 75 health after a kill, but makes you more vulnerable to melee attacks. Since you must be in melee range to kill enemies with it, make sure to take enemies by surprise with this, and use the self-heal to restore any health lost in a melee fight.
 * Attack Interval: 0.8 seconds
 * Normal Damage: 65
 * Critical Hit: 195
 * Self Heal: 75

Back Scratcher
The Back Scratcher does more damage and heals more health from health packs. However, the healing rate of Medics and Dispensers on you is decreased.
 * Attack Interval: 0.8 seconds
 * Normal Damage: 81
 * Critical Hit: 244

The Back Scratcher is useful when you rely more on health packs and less on Medics for surviving, which is useful when your team lacks Medics or you fight behind the enemy frontlines. The higher damage also makes it a better alternative close-range option.

Sharpened Volcano Fragment
The Sharpened Volcano Fragment does less damage than the Fire Axe, but ignites enemies upon a hit. Your Flamethrower is a better weapon for close-range ignition, but this weapon makes less noise than the Flamethrower's low burn sound, so it can be a stealthier way of igniting enemies. It is very useful in Medieval Mode, as it is 1 of the only 2 weapons capable of igniting enemies.
 * Attack Interval: 0.8 seconds
 * Normal Damage: 52
 * Afterburn Damage: 60 over 10 seconds
 * Critical Hit: 156

Third Degree
The Third Degree deals damage over all enemies connected by a medigun's beams. That is, hitting either the patient or the Medic healing him will damage them both. If there are several Medics healing each other in a chain or healing a single target, hitting one of them will damage all of them. This ability helps you take down enemies being pocketed by Medics that afterburn usually can't do. It also has no drawbacks so it should be used over the Fire Axe anytime.
 * Attack Interval: 0.8 seconds
 * Normal Damage: 65
 * Critical Hit: 195

Neon Annihilator
The Neon Annihilator will deal critical hits on wet enemies, which include any enemy in a body of water, one that has just exited a body of water and someone covered in Jarate or Mad Milk, but lacks the ability to get random crits. It is also able to damage sappers, but will do 20% less damage against players. It is a counterpart to the Axtinguisher, as while the Axtinguisher amplifies your main strength, the Neon Annihilator makes up for a major weakness, which is water. Since this weapon crits against wet players, it means you have a way to continue dealing damage while close to a body of water, though not every map has water, making it a bit situational. You can also work with an allied Scout or Sniper to force crits using their Jarate or Mad Milk.
 * Attack Interval: 0.8 seconds
 * Normal Damage: 52 (65 against buildings)
 * Critical Hit: 156 (195 against buildings)

The Gas Jockey's Gear
This set let's you move faster than a Medic, but makes you more vulnerable to bullets. The speed buff is very useful for a variety of situations. You can use it to chase down slower classes easily, which makes up for your Degreaser's lower afterburn. You can also stop Spies from trying to escape by chasing after them after igniting them. Your increased vulnerability to bullets means you are better off ambushing an opponent than chargin straight for them. Watch out especially for Scouts, Heavies and Sentry Guns, and use your speed to escape a difficult gunfight.
 * Consists of Degreaser, Powerjack and the Attendant hat.
 * Set Bonus: 10% faster movement speed on wearer and 10% vulnerability to bullets for wearer.

The Infernal Imp
This set is purely cosmetic.
 * Consists of the Blazing Bull hat, the Fallen Angel item and the Tail From the Crypt item.

Using the Pyro
The Pyro is almost exclusively a short-range class. They can only harass at long range, but their combination of average speed and fair amount of health make them harder to hit than Soldiers or Heavies and tougher than Scouts or Medics, and so able to avoid much hassle from Snipers or Soldiers firing rockets and able to withstand the minuscule damage from a long range minigun. Usually, the Pyro should try to get toe-to-toe with enemies as much as possible, since that's when the flamethrower is most damaging, and ambushing enemies by coming up behind them or dropping off a higher ledge often works very well. Remember though: Don't go point blank with Soldiers or Heavies unless you're certain you can pull it off. Point blank, the minigun rips you to shreds so unless you get a string of crits (backburner is good for this), it's best to light and run.

Two pyros working together do far, far better than combos such as dual demoman. One pyro can light enemies up while the other hits them with the axtinguisher, two pyros with the backburner trapping an enemy in a sea of crits or one pyro can blast an enemy straight into an ambush spot.

Offensively, a Pyro is a very effective anti-Scout class. Heavy/Medic combos can be taken down easily too, if the Pyro hides and then runs straight at the Medic and is careful not to hit the heavy, often the heavy won't notice his medic has died until it is too late.

The afterburn of the Pyro's flames also means that you can set enemies on fire, toast them for a bit, then run off and let the burning finish the job. This works well against low-health classes like Medics, Scouts and Spies (although not that well against Soldiers and Heavies). If you are under threat from enemy Spies, a paranoid Pyro who goes around trying to burn everyone on their team is a good way of rooting out disguised spies, since they catch fire and will continue to burn whilst cloaked, revealing them as an invisible blur surrounded by flames.

Pyros can also deflect incoming rockets, flares, grenades, etc, as well as put out burning teammates with the flame throwers secondary attack.

Pyros are also effective against enemy Pyros. Their flame-retardant suit means that although they can take damage from fire, they don't actually burn, and a skillful Pyro can take out an enemy Pyro with little trouble and shrug the flames off afterwards.

Defeating Pyros
Unless you have another close-range weapon like the rocket launcher or minigun and have a method of healing nearby, close-range assaults against a Pyro will likely result in your death. Staying outside the range of the flamethrower whilst continuing to attack an enemy Pyro works far better, since the range of the flamethrower is very short and many other weapons continue to be effective outside that range.

Good aim as a Sniper also helps; Pyros don't move as quickly as Scouts or Medics but they are still quite fast, but susceptible to Snipers if they can aim well. Soldiers or Heavies grinding them down from a distance also works. Basically, to beat them, stay out of the flames. As outlined before, Scouts and Spies are generally at a disadvantage when it comes to Pyros.
