The Flame Thrower (or flamethrower) is a close range weapon that also serves as a basic raiding tool. Fire sprayed from a flamethrower may obscure a target's vision and rapidly drain their health.
The Flame Thrower will start to steadily spawn fireballs once the trigger has been held long enough, and each one will damage and slow players or burn any wooden items they touch. Take care- fireballs spawned from spraying can and will burn bodies away (but their loot will fall out of them if they do).
Raiding with a flamethrower is accomplished by continuously spraying a wooden structure with fire until it shatters. Structures without a base for the fireballs to land on are very inefficient to raid with a flamethrower, since fireballs will not damage the targeted area.
