After four Nightlords and three expedition days, Heolstor the Nightlord — also called the Night Aspect — is the final obstacle between you and Nightreign’s ending. He’s the only boss in the game with two separate health bars, which means three distinct stages, each with different threats and a specific HP trigger that changes everything. Most guides say bring Holy weapons and be patient. Both are true, and neither is sufficient.
This guide covers the six exact HP values across all Depth levels, what the boss does at each phase transition, which damage types actually work in which phase (including a conflict between two major sources that will send you into the fight with the wrong weapon if you don’t know about it), and the three-character co-op setup that handles the fight most reliably. Verified on patch 1.03.5 — no changes to Heolstor have been documented in any update since launch.
HP Thresholds by Depth Level
Heolstor is the only Nightlord with two HP bars. Phase 1 (The Shape of Night) and Phase 2 (Heolstor’s true form) are separate enemies with separate pools. There are also two internal transitions — one within Phase 1 and one within Phase 2 — that don’t reset HP but change the moveset entirely.
| Stage | Depth 1 (Solo) | Depth 2 (Duo) | Depth 3 (Trio) | Trigger |
|---|---|---|---|---|
| Phase 1 — The Shape of Night | 4,984 HP | 9,968 HP | 14,952 HP | Fight begins |
| Phase 1 Internal Transition | ~60% of Phase 1 HP remaining | Dark arm emerges, greatsword drawn | ||
| Phase 2 — Heolstor the Nightlord | 11,215 HP | 22,428 HP | 33,644 HP | Phase 1 HP fully depleted |
| Phase 3 — Sky Splitter Transformation | ~50% of Phase 2 HP remaining | Boss flies skyward, rift tears open | ||
The jump from Phase 1 to Phase 2 HP is significant at every Depth. At Depth 3 in a full trio, you’re dealing with roughly 49,000 total HP across two bars. Phase 2 alone is more than twice Phase 1’s health — which is why conserving your resources during Phase 1 is the single most important tactical decision in this fight.
Pre-Fight Checklist
Check all of these before entering the Night Aspect expedition:
- Level 14 minimum. Level 13 is survivable but unforgiving. Level 14 is the recommended entry point for a standard difficulty run.
- At least one Holy weapon in the group. Holy is the only damage type that triggers Heolstor’s stagger — without it, you lose your critical-hit windows.
- Know your Phase 1 element. Holy still works in Phase 1, but Fire is equally effective there (-20% negation against the Shape of Night) and lets you save Holy weapon durability for Phase 2.
- No Strike builds for Phase 1. Strike has +10% damage negation against the Shape of Night — meaning it’s slightly weaker than neutral damage types.
- Scarlet Rot tools ready. Heolstor isn’t immune to rot, and the first application builds at 252. Sustained rot between your attack windows adds up.
- Save all Ultimate Arts through Phase 1. Use them only on Phase 2 openers or to interrupt the Cover of Darkness / Dark Shroud.
- Memorize the Sky Splitter color key. Light blue sky = Frost element. Yellow sky = Madness. Knowing this before the fight means you’re not reading the arena while dodging explosions.
- Four Nightlords defeated. Night Aspect only unlocks after completing the required remembrance quests for each of the other four expedition bosses.
Phase 1 — The Shape of Night
The Shape of Night moves slowly. Its attacks are telegraphed sweeping slashes and dashes that cover distance but give you time to read the wind-up. This phase feels manageable, and that’s the trap — the most common mistake in this fight is spending Ultimates, burning Flasks, and taking chip damage here, then entering Phase 2 already depleted.
The Shape attacks one target at a time and switches targets frequently. In co-op, use this: while Heolstor is targeting one player, everyone else gets free hitting time. The hit-and-back rhythm is the same as every Soulsborne boss — land one or two hits per opening, never three.
Damage priority in Phase 1: Holy (-35% negation, stagger), Fire (-20% negation), Slash (-15% negation), Pierce (-10% negation). Strike has +10% negation here — slightly resistant. Focus on Holy for the stagger or Fire to preserve your Holy item charges. Both are stronger here than they are in Phase 2.
The Phase 1 Internal Transition (~60% HP)
At approximately 60% of the Shape of Night’s HP — around 3,000 HP at Depth 1, 8,400 HP at Depth 2, or 8,970 HP at Depth 3 — a second dark arm erupts from the boss’s body, drawing a darkened version of the Dark Moon Greatsword. This isn’t a full phase transition: there’s no cutscene, no HP reset, no safe window. The boss immediately begins using that sword.
This internal shift matters for two reasons. First, the Shape of Night’s dashes become longer and its combo length increases, so the brief opening windows you had before get shorter. Second, it’s your signal to back off slightly and reassess positioning. Players who tunnel-vision on DPS through this moment get caught by the extended sweep radius.
Continue applying pressure, but treat this like a sub-phase. Let the combo play out once to see the new timing, then resume. You’re still not spending Ultimates yet.
Phase 2 — The Entry Danger Window
When Phase 1 HP hits zero, darkness spills from the Shape’s body and Heolstor’s true form emerges. There’s a brief cutscene-like transition — and immediately after it, Heolstor opens with the Lunging Stab & Dark Explosion. This attack can kill most characters in one hit. Sprint or dodge the moment you regain control; don’t stand still to watch the transformation animation.
Phase 2 Heolstor wields three weapons simultaneously — a straight sword, a rapier, and the greatsword — and cycles through all three in combos. The visual variety catches people off guard because the attack animations are completely different depending on which weapon is active. The hitboxes also scale with each weapon type, so the rapier thrusts have shorter range but faster recovery, while the greatsword swings cover a wide arc.
Damage priority changes in Phase 2. Holy still works (-20% negation, still triggers stagger). Lightning now matches Holy numerically (-20% negation), but here’s the critical distinction: Lightning does not trigger the stagger effect. If you’re using Lightning for the damage bonus, you’re dealing the same raw damage as Holy but losing your critical-hit windows. Against this boss, Holy is the correct weapon type in both phases — it’s not just about damage output, it’s about earning the riposte.
Slash damage note — source conflict: Fextralife’s wiki lists Slash as a Phase 2 weakness, while the Eldenpedia (wiki.gg) records Slash at +10% negation in Phase 2, meaning it’s slightly resistant. These sources directly contradict each other. Until this is community-resolved, avoid building around Slash for Phase 2 and stick with Holy, Lightning, or Pierce (-15% negation) instead.
Phase 3 — Sky Splitter Transformation (~50% Phase 2 HP)
At approximately 50% of Heolstor’s second health bar, the boss flies into the air and tears open the sky. Don’t use an Ultimate here — it won’t interrupt the transition and you’ll waste it. Sprint away from the boss’s position and stay mobile.
The rift absorbs power from a random Nightlord’s element, imbuing Heolstor’s next attacks with one of: Fire, Lightning, Holy, Poison, Sleep, Madness, or Frostbite. The sky color tells you which element you’re dealing with before the attacks land: light blue means Frost, yellow means Madness. The ground cracks in a star formation before explosions detonate — dodge the first explosion by rolling through it, then jump just before the second burst triggers.
After the Sky Splitter resolves, Heolstor returns to his Phase 2 moveset but is now faster and more aggressive. This is the moment to coordinate your stagger push: get your Wylder’s Onslaught Stake or Raider’s jump attack to connect while the boss is still mid-animation from the landing. Holy stagger here gives you an extended riposte window and potentially another one if Duchess is restaging your Ultimate Arts.
Full Attack Reference
| Attack Name | Phase | What Happens | Counter |
|---|---|---|---|
| Backstab | 2 | Teleports behind target, three-hit combo | Sidestep or roll through second hit; don’t panic-roll after teleport |
| Pouncing Combo | 2 | Three side-to-side slashes covering arena distance | Roll laterally into the slashes, not away; rolling away extends your exposure |
| Winding Thrust | 1, 2 | Charged pounce into ground impale | Dodge sideways at the moment of ground contact, not at the wind-up |
| Greatsword Lunge | 2 | Charges magic in blade, shoots forward; overhead plunge follow-up causes ground explosion | Start roll as he lunges to go through the attack; roll again as blade contacts ground |
| Cover of Darkness / Dark Shroud | 2 | Homing dark projectiles blanket the arena | Sprint in a wide circle until projectiles expire, or interrupt with a stagger Ultimate |
| Night Rain | 2, 3 | Boss kneels; purple wisps rain down with weak homing | Sprint wide circles around Heolstor until the rain stops; Ultimates can interrupt |
| Sky Splitter | 3 | Boss flies up, rift opens, explosion in star formation with random element | Roll through first explosion, jump before second; read sky color for element prep |
| Finisher Combo | 2, 3 | Long multi-hit combo ending in wide explosion; glowing ground fissures appear | Back away after the final hit; time rolls through the fissure explosions, don’t stand still |
Parry note: Heolstor is the only Nightlord in the game that can be parried. Three successive parries with the Executor’s Cursed Sword skill trigger a critical attack. The explosion-type attacks (Cover of Darkness projections) can also be deflected by the Executor by facing the boss directly — the same mechanic used against dragon lightning. The Executor’s critical hit attack power was buffed in patch 1.03.2, making this approach more rewarding than it was at launch.
Best 3-Player Party Setup for Co-Op
Three character combinations stand out for this boss. The deciding factor isn’t raw damage output — it’s stagger access and survival reliability across all three phases. For a full breakdown of every Nightfarer’s mechanics, see our Nightreign character guide; for coverage of the other four Nightlords you need to clear before this fight, the Nightlord guide covers all expedition bosses.
Composition 1: Guardian + Wylder + Ironeye (Best for Most Groups)
This is the most consistent team for players who don’t want to rely on technical execution for the win.
- Guardian (buffed in patch 1.03.2 with increased damage negation and Guard Boost) draws aggro consistently and keeps Heolstor focused, giving Wylder and Ironeye uninterrupted windows. Guardian’s passive buffs extend to the party — especially valuable during the Sky Splitter chaos in Phase 3.
- Wylder is the stagger engine. Onslaught Stake with a Holy weapon connects reliably and staggers Heolstor at close range. After every stagger, Wylder gets the riposte. Run Holy-infused weapons through both phases; Phase 2 is where the stagger-into-riposte loop earns its keep, since Phase 1 is manageable even without ripostes.
- Ironeye marks Heolstor to increase all damage taken, then outputs consistent ranged pressure during phases where melee access is limited — particularly the Sky Splitter animation and Night Rain. Ironeye’s Single Shot Ultimate staggers reliably from range and is safe to use when the boss is targeting Guardian or Wylder.
In practice: Guardian taunts, Wylder staggers and ripostes, Ironeye marks and fires. You’ll stagger Heolstor 4-6 times per phase at Depth 3 with this rotation.
Composition 2: Wylder + Duchess + Ironeye (Burst Kill Option)
If your group is comfortable with the fight and wants to run a faster kill, Duchess is the multiplier. Her Restage ability reactivates critical strikes and Ultimate Arts on the boss — meaning Wylder’s Onslaught Stake and Ironeye’s mark+Ultimate burst can be repeated within the same stagger window. In a coordinated group, Phase 2 can be over before Phase 3 even triggers.
The tradeoff: no dedicated tank means Heolstor switches targets constantly. This composition requires all three players to be comfortable dodging Phase 2’s opener (Lunging Stab) and the Phase 3 Sky Splitter independently, without Guardian absorbing pressure.
Composition 3: Guardian + Raider + Executor (Parry Specialists)
Raider was buffed in patch 1.03.2 — increased attack speed, expanded range on Totem Stela, and a new passive that boosts attack power at low HP. Paired with Guardian’s aggro control, Raider handles melee stagger duties while Executor chains parries on Phase 1’s more predictable attacks. Three successful parries from Executor triggers a critical hit that bypasses poise and resets the stagger counter.
This is the highest-skill-ceiling option but also the most damage-per-window output when executed well. Raider’s Totem Stela covers a wide zone that Guardian can bait Heolstor into, and Executor can freely parry during those moments of controlled positioning.
Advice by Player Type
| Player Type | Priority | Avoid |
|---|---|---|
| New player | Run Composition 1 (Guardian + Wylder + Ironeye). Let Guardian hold aggro, focus on dodging and using one attack per opening. Watch Phase 2’s opener — sprint the moment the transition ends. | Spending Ultimates in Phase 1. Running Strike weapons against Shape of Night. Standing still during Sky Splitter. |
| Casual player | Slot Scarlet Rot tools alongside your Holy weapon — rot will deal passive damage during your recharge periods and you don’t need to time it precisely. Ironeye’s mark does extra work here by amplifying rot damage too. | Building around Slash for Phase 2 — two major community sources contradict each other on whether it’s a weakness or resistance. Stick with Holy and Lightning to stay safe. |
| Hardcore / optimizer | Run Composition 2 (Wylder + Duchess + Ironeye) with timed Restage coordination. Aim to end Phase 2 before the ~50% Sky Splitter trigger. Three-parry Executor in Composition 3 maximizes critical damage per stagger window after patch 1.03.2 buffed Cursed Sword crit power. | Wasting Duchess Restage on Phase 1 — save it for Phase 2’s stagger windows where the riposte damage is maximized. |
Rewards
Defeating Heolstor unlocks the game’s ending and drops three rewards:
- Night of the Lord Relic (Blue, Large) — applies an affinity buff to your equipped weapon whenever you swap weapons during a run. The buff matches whatever element your previous weapon carried, effectively giving you a free greased weapon on every swap. It also increases the additional affinity damage from the buff itself.
- Sacred Erdtree Grail — unlocks a third Yellow Relic slot, giving you access to three Yellow Relics simultaneously in future expeditions.
- Character skins — cosmetic unlocks for your Nightfarer roster.
The Night of the Lord Relic is genuinely useful for weapon-swapping builds — particularly Wylder and any character running dual-element setups. It’s not just a collectible.
Frequently Asked Questions
What level should I be to fight Heolstor?
Level 14 is the recommended baseline. Level 13 is survivable, but Phase 2’s Lunging Stab opener is lethal at that level if you’re caught in it. Reach 14, clear your rune-gathering passives during Day 3, and don’t enter the Night Aspect expedition underleveled — the HP pools scale significantly at Depth 3.
Can you solo Heolstor?
Yes. At Depth 1 (solo scaling), Phase 1 is 4,984 HP and Phase 2 is 11,215 HP. The fight’s rhythm doesn’t change solo — you’re just doing all the stagger and aggro work yourself. Run a Holy weapon Wylder or Executor and focus Phase 1 with Fire options to conserve your Holy charges. The main difficulty solo is Phase 3’s Sky Splitter, where there’s nobody else for Heolstor to target during the projectile rain.
Is Holy damage required, or can Lightning replace it?
Lightning deals the same raw damage as Holy in Phase 2 (-20% negation for both). But only Holy triggers the stagger effect. If your build doesn’t have Holy access, Lightning is your next best damage option — just don’t expect stagger windows from it. You’ll need to rely on poise-breaking combos or jump attacks from Wylder and Raider to create those openings instead.
Why does the Executor work so well here?
Heolstor is the only Nightlord that can be parried, and the Executor’s Cursed Sword skill is purpose-built for parry chains. Three successful parries trigger a critical attack that ignores normal poise thresholds. Phase 1 (the Shape of Night) has more telegraphed, predictable attacks that are easier to parry reliably. The Executor’s critical hit damage was increased in the January 2026 patch (1.03.2), so the payoff per successful parry chain is higher than it was at launch.
Does Scarlet Rot work on Heolstor?
Yes — Heolstor is immune to Poison, Bleed, Frostbite, Madness, and Death Blight, but Scarlet Rot applies at 252 buildup. Once inflicted, rot ticks damage between your attack windows without requiring additional actions. Sleep also applies (threshold 542), though the buildup requirement makes it impractical compared to rot in a standard fight. Apply rot early in Phase 2 and let it work while you dodge Sky Splitter.
