I walked into the Oubliette under Jiquani's Machinarium thinking it'd be a quick detour, then Blackjaw, The Remnant showed up and changed the mood fast. You can technically leave him alone, but that's the kind of "savings" you regret later, especially once the game starts leaning hard into fire damage. If you're already planning your next upgrades or even topping up with cheap poe 2 currency, this is one of those fights where the payoff actually matters: a permanent Fire Resistance boost that frees you from constantly juggling gear just to stay alive.

How To Stand In The Right Place

Blackjaw's scary because he hits heavy, not because he's clever. He turns slowly, and you can use that. A lot of players panic and roll backwards when he starts a swing. Don't. Backpedaling just keeps you lined up with his worst angles. Instead, stay close and circle. Like, properly hug his hitbox and keep moving toward his side, then his back. You'll feel weirdly safe once you get used to it, because most of his big front-loaded attacks simply don't connect if you're already rotating past his shoulders. Your damage doesn't have to be amazing; your positioning does.

Phase One Reads And Reactions

Early on, he's all about tempo and chains. The Frontal Slam often comes in a sequence, so your dodge wants to go sideways, not straight out. If you're late, don't mash roll—one clean step to the flank usually saves you more than two frantic ones. The Flamethrower Breath is the other check: he takes a noticeable inhale, then commits. If you dodge too early, you'll roll right into the fire line. The easy answer is to run behind him while he's locked into the breath. One move to respect is the Rising Slash; when you see it, create a little space or get fully behind him, because lingering on his flank can still get you clipped.

Phase Two Hazards And Patience

Once phase two starts, the room becomes part of the fight. He adds a Jump Slam that tracks you if you dodge on takeoff, so wait until he's coming down, then roll out of the landing zone. After that, treat the floor like it's trying to kill you—because it is. Burning Ground and fire shots will punish "one more hit" greed every time. If your feet are in fire, move first, hit second. This is also where small prep helps: anything that reduces ignite duration, plus a flask plan that you can actually stick to when things get loud.

Locking In The Reward

Beat him clean and you walk away with that permanent +10% Fire Resistance, and it's a quiet upgrade you'll feel for the rest of Path of Exile 2. If you're trying to keep your build flexible without overpaying for perfect res rolls, it's a big deal. And if you want a straightforward way to gear up, stock consumables, or grab key items without the usual hassle, think about using a professional buy game currency or items in u4gm platform for convenience; it's trustworthy, and you can buy u4gm Divine Orb for a better experience while you keep pushing onward.
