Brotato Arsonist Build Guide & Fire Puddle Strategy

Feuerpfützen und Explosionen mit dem Arsonist meistern

🔓Have 12 fire puddles on the ground at the same time
⚡

Is Arsonist good in Brotato?

Arsonist is a strong specialist built entirely around burning and explosions. If you lean into elemental damage and explosion scaling, his fire puddles can clear entire waves, but you must accept doing almost no traditional melee, ranged, or engineering damage.

💪

Strengths

  • Insane AOE clear thanks to fire puddles from explosions and burning deaths
  • Scales extremely well with Elemental Damage and Explosion Damage/Size
  • Built‑in +5% Speed helps you kite enemies through fire zones
  • Burning kills can chain, creating overlapping puddles that melt tanky enemies
  • Very synergistic with burning items and elemental pets from the DLC pool
⚠️

Weaknesses

  • Melee, Ranged, and Engineering modifications are reduced by 100%, so most generic weapons and items lose value
  • Weak single‑target burst unless you stack multiple burn sources on bosses
  • Positioning dependent – you need to herd enemies through your flame zones
  • Relies heavily on finding the right elemental and explosion items
  • Can feel fragile if you neglect Max HP, armor, or regeneration while scaling damage

Arsonist Stats & Passive Ability

Base Stats
Explosions leave a puddle of fire that scales with explosion size, dealing 4x4 (+100%) burning damage
50% chance for enemies dying while burning to leave a puddle of fire dealing 4x4 (+100%) burning damage
+5% Speed
Melee Damage modifications are reduced by 100%
Ranged Damage modifications are reduced by 100%
Engineering modifications are reduced by 100%
🎮

Arsonist completely abandons traditional melee, ranged, and engineering scaling and instead turns the whole map into a maze of fire. Any explosion you create drops a fire puddle that scales with Explosion Size, and burning kills have a 50% chance to spawn additional puddles. This means your damage engine is a mix of burning uptime, explosion frequency, and how well you can herd enemies through those zones. Because Melee, Ranged, and Engineering modifications are reduced by 100%, most generic damage items and hybrid weapons lose their value. You want to focus almost entirely on Elemental Damage, Explosion Damage, Explosion Size, and survivability stats like Max HP, armor, dodge, and HP Regeneration. Play evasively with your innate +5% Speed: kite packs through Molotovs, rocket blasts, and burning zones while your puddles slowly erase anything that steps into them.

Strategy

🌱Early Game

In the early waves your goal is to get consistent burning on as many enemies as possible while staying alive. Take Molotov Cocktail or Wand as soon as you can – both apply burning and Molotov already creates fire puddles that scale naturally with Arsonist’s kit. Supplement them with Shredder or Rocket Launcher if they appear, because even low‑tier explosions instantly become fire puddles. On level‑ups, prioritize Elemental Damage and Max HP first, then HP Regeneration or dodge if survivability feels shaky. In the shop, grab cheap elemental power like Boiling Water, Toxic Sludge, and Fuel Tank, plus utility such as Coffee or Gummy Berserker for Attack Speed and Beanie or Terrified Onion for Speed. Try to keep your weapons count reasonably high so you can tag enemies with burns quickly and start chaining fire puddles as soon as waves get denser.

⚡Mid Game

By mid game (waves 7–13) Arsonist wants to fully lean into explosions plus burning. Aim for a core of 4–6 weapons that all either explode or apply burns: Molotov Cocktail, Shredder, Rocket Launcher, Fireball, Flamethrower, and Wand are your best candidates. The more overlapping explosions you cause, the more permanent fire zones cover the map. Item‑wise, start stacking big multipliers: Explosive Shells, Plastic Explosive, and Dynamite massively increase how far your fire puddles reach and how hard they tick. Pick up Greek Fire to convert every burn into percentage current HP damage, which helps a lot versus elites and bosses once your fire carpets are down. Complement damage with sustain: Shmoop, Alien Magic, Mushroom, Campfire, or Sad Tomato give HP Regeneration; Alien Baby, Broken Mouth, Padding, and Warrior Helmet add Max HP and armor so you can afford to stand near packs while guiding them through flames.

🔥Late Game & Bosses

In late game waves and boss fights, you play almost like a zoning control character. Your objective is to cover as much of the arena as possible with overlapping explosions and fires, then run circles around elites and bosses while they sit in an ocean of burning puddles. Fireball, Rocket Launcher, Shredder, and Molotov Cocktail are still your best tools for instantly seeding huge fire zones. Make sure Explosion Size and Elemental Damage are very high by this stage, with several of Explosive Shells, Plastic Explosive, Greek Fire, Fuel Tank, and Wolf Helmet or Gnome if you find them. Round out defenses with Tardigrade, Octopus, Medikit, Leather Vest, or Warrior Helmet so that stray hits don’t immediately end the run. Against bosses, keep moving, drag them through existing fire carpets instead of chasing, and rely on Greek Fire’s percentage damage plus your stacked burns to chew down their health even if their raw HP is high.

Best weapons for Arsonist

Molotov Cocktail is perfect for Arsonist because it already creates fire puddles and applies burning, which then chain into even more puddles via his passives. It scales purely with Elemental Damage, dodging his penalties to Melee, Ranged, and Engineering.

Elemental DamageAttack SpeedExplosion SizeSpeed

Shredder fires many exploding projectiles that reliably trigger Arsonist’s explosion‑to‑puddle passive. It clears crowds at range, stacking multiple fire zones in front of you and multiplying the impact of Explosion Damage and Size bonuses.

Elemental DamageExplosion DamageExplosion SizeAttack Speed

Rocket Launcher provides large, infrequent explosions that drop oversized fire puddles. With high Explosion Size and Greek Fire, a single rocket can set up a deadly zone that deletes waves and chunks bosses as they walk through it.

Explosion SizeExplosion DamageElemental DamageRange

Fireball combines strong burning damage with on‑hit explosions, double‑dipping Arsonist’s synergies. Each cast both burns enemies and creates an explosion that drops a fire puddle, quickly turning whole packs into chain‑reacting infernos.

Elemental DamageExplosion DamageAttack SpeedRange

Flamethrower excels at tagging huge numbers of enemies with burning as they enter your kill zones. While it doesn’t explode by itself, it guarantees that almost every enemy is burning, maximizing the chance for burning deaths to spawn extra puddles.

Elemental DamageAttack SpeedRangeSpeed

Wand is a simple, reliable burning applicator that scales with Elemental Damage and ignores Arsonist’s melee/ranged penalties. It’s an excellent early‑game weapon or filler in your lineup to guarantee consistent burn uptime.

Best items for Arsonist (core item pool)

Greek Fire converts every burn tick into percentage current HP damage, which stacks brutally with Arsonist’s constant burning and puddle spam. It lets your fires scale into late game and makes elites and bosses melt as long as they stay ignited.

Explosive Shells gives huge boosts to Explosion Damage and Size, directly scaling how hard Arsonist’s fire puddles hit and how wide their coverage is. The generic Damage penalty barely matters because your true DPS comes from burns and puddles, not base weapon damage.

Plastic Explosive massively increases Explosion Size, which in turn increases the size of the puddles left by Arsonist’s explosions. Bigger explosions mean more reliable coverage of the arena and easier kiting of entire packs through overlapping fire zones.

Dynamite is a straightforward multiplier to all your explosions, and therefore to your puddle DPS. It stacks well with Explosive Shells and Plastic Explosive, turning every Shredder shot and rocket into a devastating fire starter.

Fuel Tank gives a chunky Elemental Damage boost with penalties to stats Arsonist barely cares about, thanks to his 100% reduction to Melee and Ranged modifications. It’s efficient scaling that directly improves your burns and puddles.

Toxic Sludge is efficient flat Elemental Damage in exchange for a small amount of dodge. The damage increase applies to every burn tick and synergizes well with Greek Fire and Blazemander, while the dodge loss can be offset with other defensive items.

Boiling Water trades a small amount of Max HP for pure Elemental Damage, which is ideal for an offense‑first Arsonist. Early copies dramatically speed up your clear, and later you can compensate the health loss with Max HP and armor picks.

Campfire gives both Elemental Damage and HP Regeneration – exactly what Arsonist wants – for a small Speed penalty. You can offset the Speed loss with Beanie, Terrified Onion, or Fossil: Left Leg while enjoying the double offensive and defensive scaling.

Candle reduces enemy spawns but gives Elemental Damage and HP Regeneration. Fewer enemies mean less clutter on screen while your fires still annihilate everything; the generic Damage reduction is negligible because burns and puddles do most of the work.

Snake lets burning spread to an additional enemy, which is perfect for amplifying Arsonist’s fire‑on‑death puddle chains. One ignited target can quickly turn into a whole pack burning and dropping puddles when they die.

Eyes Surgery makes burning activate faster, effectively front‑loading your burn damage so enemies die sooner and start spawning puddles earlier in each wave. The extra Elemental Damage stacks well with Greek Fire, while the Range penalty is minor for most elemental setups.

Arsonist High‑Difficulty Strategy

🌱

Early Game

On high difficulty, play very safe early: pick Molotov or Wand and focus on Elemental Damage, Max HP, and a bit of Attack Speed. Avoid greedy economy items that cost HP or defense unless you already feel comfortable. Kite small groups through Molotov puddles instead of diving into the middle of packs.

⚡

Mid Game

In mid game, lock in a full set of explosive and burning weapons – Molotov, Shredder, Rocket Launcher, Fireball, Flamethrower, and Wand are ideal. Prioritize Explosive Shells, Plastic Explosive, Dynamite, Greek Fire, and strong defensive pieces like Shmoop, Leather Vest, Warrior Helmet, and Octopus. Use your Speed to herd enemies into overlapping fires while avoiding getting surrounded.

🔥

Late Game

Late game, you should control the arena with massive explosion‑sourced puddles. Maintain movement and drag elites and bosses through your carpets of fire instead of face‑tanking. Stack more Explosion Size and Elemental Damage if you see them, then fill remaining slots with armor, HP Regeneration, and panic‑savers like Tardigrade or Medikit so random hits don’t end the run.

💡 Arsonist thrives on long fights and dense waves when his puddles can stack up. On high difficulty, your success hinges on quickly establishing a burning engine, scaling Explosion Size and Elemental Damage, and never neglecting defenses. Think of every rocket, grenade, and Molotov as setting up space control that you then exploit by kiting enemies through a constantly expanding inferno.

Arsonist FAQ

1How do I unlock Arsonist in Brotato?▼

Arsonist is unlocked by having 12 fire puddles on the ground at the same time in a run. Focus on burning and explosion weapons like Molotov Cocktail and Rocket Launcher, then stack Explosion Size so each blast leaves a larger puddle.

2Which weapons are best for Arsonist?▼

Arsonist wants elemental and explosive weapons that create puddles or apply burns: Molotov Cocktail, Shredder, Rocket Launcher, Fireball, Flamethrower, and Wand are top picks because they either explode constantly or reliably ignite enemies.

3Which stats should I prioritize on Arsonist?▼

Prioritize Elemental Damage, Explosion Damage, and Explosion Size first, followed by Max HP, HP Regeneration, armor, and some Speed. Melee, Ranged, and Engineering modifiers are heavily reduced for Arsonist, so generic damage from those stats is rarely worth buying.

4Are melee or ranged damage items good on Arsonist?▼

Generally no. Arsonist reduces Melee Damage, Ranged Damage, and Engineering modifications by 100%, so most items that only grant those stats do almost nothing for you. Focus instead on Elemental Damage and explosion‑centric items like Explosive Shells and Dynamite.

5How do I handle elites and bosses with Arsonist?▼

Set up overlapping fire zones using Rocket Launcher, Fireball, Shredder, and Molotov Cocktail, then kite elites and bosses through them instead of standing still. Greek Fire helps a lot by adding percentage HP damage to every burn, letting bosses slowly melt even if their raw HP is huge.
