Speedy Exit	Wildfire increases your movement speed, aiding both offense and defense.
Slow Cook	Enlarges ground fires and strengthens their negative effects.

Up In Flames	Further increases Molotov radius with small branching explosions.
From The Ashes	Allows you to revive yourself once per match with Wildfire.

Best Firebug Weapons for This Build

This build relies on straightforward weapons suitable for close combat and quick igniting of enemies.

Early Game Weapon:
For starters, the IR-50 Brimstone is excellent. It delivers good damage and ignites foes and ground easily, helping you stick to your build from the beginning. Upgrading to a better secondary weapon like the Pyre .357 can be considered if you have extra funds, but it’s not necessary immediately.

Late Game Weapon Options:
When you reach the later stages, some strong choices include:

Weapon	Reasoning
Dragon’s Breath	A shotgun that ignites enemies with high damage, especially effective with its secondary fire mode firing two shots simultaneously. Great for taking down tougher foes quickly.
Incinerator M7	A flamethrower that spreads flames across enemies and ground, making fire effects more accessible. It doesn’t deal as much damage as the Dragon’s Breath but excels in effect interaction over raw damage.

Both options provide solid performance. The Dragon’s Breath is better for solo or small team play, helping to eliminate big enemies faster. The Incinerator M7 is ideal for large groups, especially when playing with many allies, as it makes managing vast numbers of enemies easier.
