The shishkebab, in addition to its Melee damage, will also set the target on fire, dealing 2 damage per second for 5 seconds. The Pyromaniac perk will also increase the shishkebab's melee damage and boost fire damage from 2 to 3 damage per second for 5 seconds. Any humanoid companion can use a shishkebab. Like all custom weapons, it can be upgraded with v2 or v3 schematics.
As it is constantly on fire, the shishkebab will set off gas leaks if the player walks through one with the sword drawn. The same applies if a companion has it equipped.
When equipped, the player character and their companions will also wear an oven mitt on their right hand - presumably as protection from the heat.
The shishkebab is one of the weapons that can burn Harold in the quest Oasis.
Repeated slashes on a dead body may form an "eternal fire" on the body itself, or the place where the body is laying. This does not affect gameplay, and usually disappears upon leaving the area and returning. This effect can also be seen on dismembered limbs.
Oddly, the shishkebab weighs less than half the total weight of the components used to create it. This could be because parts that were not needed were discarded when creating the weapon.
A series of twelve tally marks appear on the shishkebab's gas tank, but are not present on the motorcycle gas tank item.
Despite using a small gas tank, the shishkebab requires no refueling.
Originally called the "shishkesword", according to the label on a piece of concept art.
