GW2 Flamethrower Scrapper build guide

Full Berserker with Dragon on the rings and accessories — a pure power, precision and ferocity setup, no condition or boon duration to chase. Engineer wears medium armour, so the named ascended Berserker set is the Leatherworker's Zojja's pieces. Your trinkets are stat-selectable ascended, so pick Berserker on the amulet and back and Dragon on the rings and accessories. Exotic Berserker is within a few percent and fine for all of open world.

One picture. You deal damage, that damage becomes barrier, so you stop dodging and just keep attacking — and disabling foes tops up the boons that make you hit harder.

Impact Savant is the engine. A share of every strike you land comes back as barrier. On a power build that is a constant wall of health you did not have to heal for — which is why dodging becomes optional and you can simply camp your two skill bars. Rune of the Scholar rewards staying healthy — bonus damage while your health is high — and Impact Savant keeps that barrier up, so the tankiness and the damage feed each other.

Two of your three utility slots are kits — the Flamethrower and the Elite Mortar Kit — so your five-skill bar is really twenty skills. Medic Gyro is your heal; Blast Gyro and Shredder Gyro bring wells for damage, superspeed and crowd control; and the Flamethrower is where you live for clumps of enemies.

Healing skill

Medic Gyro is your healing skill — a well that heals you and nearby allies over a few seconds. Every engineer utility also has a unique toolbelt skill, and Blast Zone blasts your heal’s toolbelt skill for you automatically, so pressing heal drops a free blast finisher for extra Might or healing. On top of the barrier from Impact Savant, that is a lot of low-effort sustain for one button.

Three lines: Firearms for critical damage, Alchemy for sustain and the disable payoff, and Scrapper for barrier, superspeed and the boons that turn into damage.

How the engine actually works

Firearms is your damage multiplier. High Caliber gives extra critical chance against anything at close range — which, on a hammer-and-flamethrower build, is everything — and No Scope turns those crits into Fury, which becomes Ferocity, so your criticals hit harder the more you land.

Heavy Metal then raises your critical chance and critical damage against foes below a health threshold, so your damage ramps as targets drop. It is an execute trait, and it is why packs melt once they are softened up. Some flamethrower builds run Juggernaut in this slot instead, for pulsing Stability and Might while the kit is out; this one takes No Scope and Heavy Metal for the extra critical damage, since Might is already covered elsewhere.

Alchemy is sustain and setup. Health Insurance boosts the healing you receive, and Blast Zone drops a blast finisher whenever you use your heal's toolbelt skill — free might or healing off a field.

The key trait is Equal and Opposite Reaction: every time you disable an enemy you gain Quickness and Stability. Weave your crowd control in on cooldown and you keep both up almost permanently — the Quickness speeds your rotation, and the Stability is what powers the Scrapper line.

Scrapper turns Stability into damage. Mass Momentum grants Might while you have Stability, Applied Force converts stacked Might into bonus power, and Object in Motion increases your strike damage for every boon you are holding — Stability, Swiftness and Superspeed all count.

And underneath it all sits Impact Savant, the Scrapper grandmaster minor, converting a share of your strike damage into barrier — the passive that makes this build so hard to kill. The exact major picks come from the build code above; decode it in-game to confirm.

There is barely a rotation — you camp two skill bars and press the good buttons off cooldown. The priority: keep crowd control flowing (for Quickness and Stability), stay on the Flamethrower for clumps, and drop to Hammer for cleave and reflects.

Blast the lightning field. Thunderclap (Hammer 5) drops a lightning field — whirl Electro-whirl (Hammer 2) inside it, and Thunderclap also procs Relic of Fireworks for a strike-damage burst.

Combos and crowd control

Crowd control is your damage. Every disable feeds Quickness and Stability through Equal and Opposite Reaction, and Stability is what the whole Scrapper line runs on. Do not sit on your CC — spend it on cooldown.

Flamethrower for packs, Hammer for single targets. Flame Jet is a short-range cone that shreds clumps at mid range; Air Blast (Flamethrower 3) reflects projectiles and knocks foes back, and Napalm (Flamethrower 5) lays a fire field you can blast for Might. On a single target the Hammer’s melee cleave and its reflects (Electro-whirl, Shock Shield) do more. Between them the Hammer and Flamethrower are your main damage source, and the boons your crowd control hands out are the damage modifiers on top — the strong area damage and crowd control the kit is known for.

Barely dodge. Impact Savant keeps a wall of barrier up as long as you are dealing damage, so your job is to keep attacking, not to reposition. Save your actual dodges for the big telegraphed hits.

What it is best at, and what it is not:

This is the comfort pick of the Scrapper builds — low-intensity, forgiving, low on mechanical complexity, extremely tanky, and it never has to stop attacking. It gives up the permanent-Quickness group support of the meta Power Hammer Scrapper and the raw single-target of a burst build. Take it to relax through open world, hold a spot in a meta event, and never think about your health bar.

Best for: solo open world, meta-event trains, and anyone who wants a build they can play tired. Not for: speed-killing a lone champion or topping a damage meter.

Paste this into the in-game build template. The traits and skills above are generated from this code, so they cannot contradict it.
