Pyromaniac

Pyromaniac is a perk in Fallout 2, Fallout 3, Fallout: New Vegas, Fallout: The Roleplaying Game, and Fallout Tactics. It is a skill in Fallout: Brotherhood of Steel.

Fallout 2 and Fallout Tactics
In Fallout 2, the most violent fire-based death animation will always be used, similar to that of the Bloody Mess trait.

Affected weapons

 * Flamer (Fallout) and Flamer (Fallout Tactics)
 * Improved flamer

Fallout 3
With the Pyromaniac perk, you do +50% damage with fire-based weapons, like flamers and Shishkebabs. This only increases the base damage done by these weapons, not the lingering "burn" effect.

Affected weapons

 * Shishkebab
 * Flamer
 * Firelance
 * Heavy incinerator
 * Rapid-torch flamer
 * Slo-burn flamer

Bugs

 * The Burnmaster, the Nuka-grenade, and the Zhu-Rong v418 Chinese pistol are unaffected by the perk. The guide lists these as being affected by this perk, but the weapons aren't on the form list - this is most likely an oversight by the developers.
 * Any flamers that are brought back by the Gary-23 glitch from Operation: Anchorage are also unaffected. The reason for this was probably because weapons from the expansion were not meant to be brought back, thus they are not affected by this perk.

Fallout: New Vegas
With the Pyromaniac perk, you do +50% damage with fire-based weapons, like the flamer and Shishkebab.

Affected weapons

 * Flamer
 * Shishkebab
 * Incinerator
 * Heavy incinerator
 * Incendiary grenade
 * Fire bomb
 * Sonic emitter - tarantula
 * Sterilizer glove
 * Saturnite fist super-heated
 * Flare gun
 * Gehenna
 * Cleansing Flame

Bugs

 * While fire-based, ammunition is not affected by the Pyromaniac perk.
 * Even though weapons like the Shishekebab are affected by the Pyromaniac perk, the additional burning damage is not boosted.
 * While this perk requires an Explosives skill of 60 to be unlocked, the only explosive items affected by the perk are the incendiary grenade and the fire bomb. This was confirmed by Joshua Sawyer to be unintentional; the perk was meant to be dependent on the Energy Weapons skill, which governs most ranged fire-based weaponry.
 * This perk does not affect the cosmic knife super-heated, despite it being capable of setting enemies on fire.

Fallout: The Roleplaying Game
The damage dealt using fire-based weapons increases by +1d6 per rank. Each time this perk is taken, the level requirement increases by 4.

Affected weapons

 * Flamer
 * Heavy Incinerator
 * Molotov cocktails
 * Shishkebab
 * Flamer barrel mods

Fallout: Brotherhood of Steel
Each level of this skill increases the player characters Critical Chance for +5% (up to a maximum +25) when using fire-based weapons. To take it, the player must be Level 5.
