Pyromaniac

Pyromaniac is a Fallout 2, Fallout 3, Fallout Tactics, Fallout: New Vegas and Lionheart perk as well as a Fallout: Brotherhood of Steel skill.

Fallout 2 and Fallout Tactics
The in- game description of this perk reads as follows:

''This Perk will make your character do horrible things with fire &mdash; to other people. +5 points of damage with fire-based weapons.''

In Fallout 2, the most violent fire-based death animation will always be used.

Fallout 3
With the Pyromaniac perk, you do +50% damage with fire-based weapons, like the Flamer and Shishkebab.

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 this 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.
