Key takeaways
- Poise is the real health bar. Every boss has a hidden poise meter that light attacks chip and heavy attacks reset. Break it at roughly 40% and you get a free stagger long enough for a full three-hit combo. This is why trading light hits is almost always better than fishing for one big swing.
- Range band matters more than damage. Standing 1.5–2 m away — just at the edge of your weapon’s reach — forces most bosses into their slow overhead instead of their gap-closer. Step in to 1 m and they open with the fast two-hit jab instead. The same boss, two completely different fights.
- Never trade two hits. Boss recovery animations look longer than they are. The rule that holds across every encounter: one light plus one heavy, then reset. The second heavy is what kills runs.
Every boss in Broken Blade can be beaten repeatably with the same three-step loop: bait the combo finisher, roll through the final hit, and punish the exposed weak point with two heavy attacks before disengaging. None of these fights are damage races — they are pattern tests, and each one has a fixed punish window you can memorize in three or four attempts rather than thirty.

Rustbound Warden — the first real wall
Attack patterns
- Three-hit cleave. 18-frame wind-up on swing one, 9 frames on swings two and three. Roll through the third swing, not away from it — the arc extends 2 m behind the boss’s feet.
- Shield bash. Unblockable and tracks your position for about 0.4 seconds before launching. Strafe left; there is no hitbox on the left side below shoulder height.
- Ground slam. A shockwave ring expands to 6 m over half a second. Roll toward the boss to stay inside the ring rather than sprinting out of it — you will not outrun it.
Weak point and punish window
After the slam the Warden kneels for roughly 1.8 seconds, exposing the left knee joint at 2.5× damage. Two heavy attacks fit comfortably in that window. A third will always eat the recovery swipe.
Positioning
Orbit toward the boss’s shield side — your right when facing it. The cleave arc only covers 180° on the weapon side, so circling shield-side reduces your dodge count by about half. Keep the arena’s broken pillar at your back; the Warden’s charge clips it and cancels early, giving you a free punish.
Twin Fangs — the duo fight that isn’t a duo fight
Only one of the two is ever aggressive. The passive one re-engages roughly 9 seconds after the aggressive one finishes a combo, which means you have a hard 9-second window to deal damage, reposition, or heal. Kill the spear-wielder first: it has lower poise, a shorter punish window, and its lunge is the one that catches you mid-heal.
- Spear lunge. Telegraphs with a 0.6-second crouch. Its back is exposed for 1.2 seconds after the lunge whiffs — this is the entire fight.
- Axe overhead. Slow, high damage, breaks guard. Simply walk backward; it has no forward tracking once committed.
- Paired charge. Triggers below 50% combined health. Hug the arena wall — the charge path is always a straight line between the two bosses.
Ashfall Sentinel — the arena is the boss
The arena is roughly 22 m × 18 m with four pillars spaced at 6 m intervals. The Sentinel’s attacks ignite the floor in 4 m patches that burn for 6 seconds, so the pillars are your only safe line-of-sight breaks. Fight in the outer ring, not the center — the center has no cover and the vent cycle covers it completely.
- Phase 1 (100–70% health). Single-target fireballs, dodge sideways. Two free hits after each.
- Phase 2 (70–35%). Adds a rotating beam. Never dodge backward from it — strafe with the rotation and you can attack while it sweeps past.
- Phase 3 (below 35%). Vent cycle every 20 seconds. The core opens for 2.4 seconds and takes 2× pierce and lightning damage. This is the only phase where you should be greedy.
The Broken Blade — the mirror fight
The final boss copies your weapon class, so the counter-intuitive advice is to enter with the moveset you know best, not the one with the highest damage. Its poise never breaks from chip damage; it only staggers after you land a full three-hit combo without being interrupted, which means the entire fight is a test of the “one light, one heavy, reset” rule. Punish windows are only about 0.9 seconds, so single heavy attacks are the correct answer here — two-hit punishes will get you killed.
Boss cheat sheet

|---|---|---|---|---|---|
| Rustbound Warden | 4,200 | Left knee after slam | Blunt | 1.8 s | 18–22 |
| Twin Fangs | 2,600 each | Spear-wielder’s back | Slash | 1.2 s | 24–28 |
| Ashfall Sentinel | 6,800 | Core during vent cycle | Pierce / Lightning | 2.4 s | 32–36 |
| The Broken Blade | 9,500 | None — poise break only | Any (mirrored) | 0.9 s | 40+ |
Pick your build by situation, not by tier list
Equip load determines your dodge frames, and that single number changes which bosses are hard. Light load (under 30%) gives 13 invincibility frames at 0.22 seconds; medium (30–70%) gives 11 at 0.18; heavy (over 70%) gives 9 at 0.15 but adds hyper armor to heavy attacks.
| Your situation | Load target | Weapon | Why it works |
|---|---|---|---|
| First playthrough, stuck on Warden | Heavy (70–85%) | Blunt hammer, 12+ poise armor | Hyper armor lets you finish the knee punish without being knocked out of it |
| Struggling with Twin Fangs | Medium (50–65%) | Fast slash, 1.0–1.2 m reach | Balanced frames let you dodge the lunge and still land the back punish |
| Ashfall Sentinel, low health pool | Light (under 30%) | Pierce spear + lightning buff | Fast rolls clear the 4 m fire patches that heavy rolls do not |
| Final boss, no-hit attempt | Light (under 25%) | Anything you’ve used for 10+ hours | Mirror fight punishes unfamiliar recovery frames hardest |
| Co-op with a friend | Medium | One blunt, one pierce | Boss health scales roughly 1.6× but stagger thresholds do not |
Positioning rules that carry across every arena
- Fight in the outer ring of any arena. Center-fighting removes your escape lane and puts you inside area attacks.
- Keep one pillar or wall within two dodge rolls. Every boss with a charge has a straight-line path you can break on geometry.
- Heal only during a punish window, never during a reset. Healing mid-combo is the single most common cause of a lost attempt.
- Circle consistently in one direction per boss and never reverse. Reversing puts you in front of the follow-up swing.
The low-risk repeat loop
Rest at the checkpoint, restock 6–8 throwing knives and 3 healing items, then run the boss with a single goal for the first two attempts: don’t attack, just count the combo enders and dodge. On attempt three, add punishes only on the windows you’ve confirmed. This costs about 10 minutes per boss and removes nearly all randomness from the fight, because none of these bosses have a genuinely unreactable attack once you know which swing ends the string.
FAQ
What level should I be for each boss?
The levels in the cheat sheet above are comfortable, not required. Weapon upgrade level matters more than character level — a +6 weapon at level 20 outperforms a +3 weapon at level 30.
Is blocking ever better than rolling?
Only against the Axe overhead in Twin Fangs and the Sentinel’s single fireballs. Everything else is either unblockable or drains enough stamina that you lose the punish window.
Does co-op make fights easier?
Usually yes, but boss health scales roughly 1.6× while stagger thresholds stay fixed. Two players running blunt weapons break poise faster than the health increase compensates for.
