If you’re playing Wylder in Elden Ring Nightreign, you’ve probably made both of these mistakes: firing Onslaught Stake uncharged because you panicked, then watching the boss absorb it with its stance bar intact; or holding a fully charged blast for the perfect moment, only to trigger it right as a Nightlord enters phase two and its stance meter resets entirely.
The mechanic isn’t communicated clearly in-game. There’s no visible stance bar, no indication of how close a boss is to staggering, and no signal that timing matters as much as execution. This guide fixes that with a per-Nightlord stagger hit count table, the confirmed HP thresholds where stance resets during phase transitions, and specific deployment windows for each boss where Onslaught Stake either forces a stagger or cleanly cancels a dangerous mechanic.
Mechanics verified as of June 2026, Patch 1.03.x. Stagger hit counts reflect community testing from the Elden Ring Nightreign wiki and may shift with future patches.
Quick Start: Onslaught Stake at a Glance
- Fully charge against any grounded, stationary Nightlord — most break in one charged hit
- Fulghor and Caligo are the exceptions: both require two charged hits, or three uncharged
- If a boss is approaching 50–60% HP and starting enrage animations, hold — stance resets at phase transitions
- Against Gnoster, save Onslaught Stake until the two insects merge into a single target
- Killing any enemy with Onslaught Stake retains 75% of your Ultimate Art Gauge — prioritise kill shots when possible
- Use uncharged only to interrupt a specific dangerous move immediately, or to keep partial gauge for a rapid second attempt
How Onslaught Stake Works
Onslaught Stake is Wylder’s Ultimate Art — an iron stake that detonates in a large fire explosion directly in front of you. The initial hit splits evenly between fire and physical damage, meaning boosting either stat increases the skill’s total output equally. A fire-up relic and a phys-up relic both contribute identical damage to the direct detonation.
The charged and uncharged versions aren’t just different flavours of the same attack:
- Uncharged: Deals approximately 60 stance damage, flings Wylder backward from the blast, and retains a small portion of the Ultimate Art Gauge
- Charged: Deals approximately 120 stance damage, plants Wylder’s feet to prevent knockback, completely drains the gauge, and produces a larger explosion radius with a longer stagger window
During the entire wind-up animation — from the moment you hold the button to the moment of detonation — Wylder is fully invulnerable. A Nightlord committing to a telegraphed slam or wide swing is a direct opportunity: start charging immediately and tank straight through the hit while the stake builds.
One mechanic many Wylder players miss: if you kill any target with Onslaught Stake, you recover 75% of the gauge cost. Against weaker field elites near the night-three encounter area, timing the skill to land a killing blow means entering the Nightlord room with your gauge nearly recharged. This is the most efficient use of the skill outside of stagger sequences.

Onslaught Stake Stagger Table — Hits Required Per Nightlord
Stance is an invisible resistance bar that depletes when you deal specific types of damage to a boss. When it reaches zero, the boss staggers and becomes vulnerable to a critical hit follow-up. The bar recovers quickly if you stop dealing stance damage, so consecutive hits in the same window are what matter — a second Onslaught Stake fired immediately after the first lands counts; one fired ten seconds later almost certainly does not.
The hit counts below reflect community-tested data. Values assume no relic damage bonuses beyond the base skill — fire or physical relic buffs increase stance damage proportionally and can reduce these thresholds by one hit in some cases.
| Nightlord | Uncharged Hits | Charged Hits | Key Note |
|---|---|---|---|
| Gladius, Beast of Night | 2 | 1 | Phase 2 torpedo clones — hold during clone phase |
| Adel, Baron of Night | 2 | 1 | Best window after Adel’s air attack recovery |
| Maris, Fathom of Night | 2 | 1 | Use during calm tidal phase, predictable movement |
| Libra, Creature of Night | 2 | 1 | Position carefully before Condemned phase |
| Heolstor, the Nightlord | 2 | 1 | Confirmed stance: 130. Best window: charge walk-under |
| Gnoster, Wisdom of Night | 2 (combined form only) | 1 (combined form only) | Wasted in split form — save for post-merge |
| Fulghor, Champion of Nightglow | 3 | 2+ | Coordinate second hit with a teammate |
| Caligo, Miasma of Night | 3 | 2+ | First charged hit also cancels Frost Shard |
| Harmonia, Weapon-Bequeathed (DLC) | Data pending | Data pending | Phase 2 revival at ~70% HP — treat as hard tier |
| Straghess, Traitorous (DLC) | Data pending | Data pending | Limited community testing; expect 2–3 charged |
The pattern is clear: five base-game Nightlords break in one charged hit (easy tier), two require two or more charged hits (hard tier), and Gnoster is a timing problem rather than a hit count problem. If you’re new to Wylder, start by landing clean single-charged stagger sequences against Gladius and Heolstor — the immediate win rate increase from a confirmed stagger on those two encounters is the fastest way to build the habit.
For a comparison of how Recluse and Executor stack up against each Nightlord in terms of raw DPS, see our Recluse vs Executor guide — Onslaught Stake’s stagger value changes the team math considerably on hard-tier bosses.
HP Thresholds: When Stance Resets
The most wasteful Onslaught Stake use is a fully charged hit that lands exactly as a Nightlord enters its second phase. Phase transitions reset or significantly refresh the stance bar, meaning you’ve spent your entire gauge and still don’t get the stagger.
Here’s what’s confirmed or community-reported for each boss:
- Heolstor, the Nightlord: Phase 2 triggers at approximately 60% HP, marked by Heolstor drawing the massive greatsword from his back. If you’re burning through his health quickly in the first phase, hold Onslaught Stake until the transition completes and his new attack pattern begins.
- Gnoster, Wisdom of Night: Phase 2 at approximately 50% HP, when Animus and Pest merge into a single combined target. This transition is also the signal to fire immediately — the merge animation is the optimal Onslaught Stake window.
- Gladius, Beast of Night: Phase 2 produces torpedo-clone versions of Gladius moving erratically across the arena. The real Gladius is difficult to identify and hit during this window. Hold Onslaught Stake and wait for the clone phase to resolve before committing.
- All Nightlords (general): Based on observed combat across multiple encounters, most phase transitions occur in the 50–60% HP range. Clear audio and visual cues — roaring, a body glow, a brief pause in attack frequency — reliably signal the transition. When you see those signs, hold the gauge and confirm the transition before firing.
A useful rule: if a Nightlord has been at 50–60% HP for more than ten seconds without a dramatic animation shift, the transition likely already happened and the stance bar has reset. You’re clear to begin building toward the next charged hit.
Boss-Specific Deployment Windows
The hit count table tells you how many Onslaught Stakes you need. The deployment window question is different: when does the boss give you the physical opportunity to land them cleanly?
Caligo, Miasma of Night
Caligo has an explicit interrupt use that’s separate from the stagger sequence. When she begins building the Frost Shard attack — a slow, increasingly bright visual build-up followed by a wide ice explosion — firing Onslaught Stake mid-build cancels the attack entirely. This works even uncharged. It’s worth doing as a pure defensive move even when you don’t have a second charged hit ready for the follow-up stagger. The practical approach: use the first charged hit for the Frost Shard cancel, then coordinate the second charged hit with a teammate for the stance break. See our Caligo boss guide for the full attack pattern timing.
Gnoster, Wisdom of Night
In split form, Onslaught Stake’s blast connects to whichever insect it hits, but the stance damage doesn’t transfer between the two — so you’re spending full gauge for partial effect. Hold the skill until the two merge at the ~50% HP threshold. After the merge, the best window is the 15 seconds following Gnoster’s orbital laser attack, when Animus lands and remains briefly grounded on the arena floor. Both a charged Onslaught Stake and a well-timed teammate ultimate connect cleanly in that window and will break stance with one charged hit. See our Gnoster boss guide for laser timing and positioning.
Heolstor, the Nightlord
Heolstor’s charge attack locks him into a straight-line path across the arena. Walking under his body during the charge gives you a clean, close-range blast directly below his hitbox — Heolstor can’t pivot mid-charge, so the window is reliable and repeatable. His confirmed stance value is 130; one fully charged Onslaught Stake at base values breaks it in a single hit. See our Heolstor boss guide for full phase-two strategy after the stance break.
Fulghor, Champion of Nightglow
Fulghor moves fast and rarely stands still long enough for a comfortable charge wind-up. The most consistent window is after his multi-hit combo finishes — when the chain ends, he pauses briefly before resetting. Start charging the moment his last hit lands and fire before he begins moving again. Because Fulghor needs two charged hits, the second attempt must be coordinated with a teammate targeting the same recovery pause. For full attack pattern breakdowns and the safe-zone map, see our Fulghor boss guide.
Gladius, Adel, Maris, Libra
All four break in a single charged hit and offer relatively generous grounded windows. The approach for each: wait for any slam, dive, or heavy attack to complete, then fire during the recovery pause before the boss resets. These four encounters are the ideal practice runs for developing the charge timing before attempting coordinated two-hit sequences on Fulghor and Caligo.
Relics That Change the Numbers
Two relic interactions directly affect what Onslaught Stake deals:
Fire Spread (Art activation spreads fire in area): Adds a lingering flame patch to the blast zone after detonation. This secondary effect scales with fire damage bonuses only — not physical damage upgrades. If you’re running a physical-heavy build, the fire spread contributes less than it appears to from the visual effect.
Giant’s Red Braid with Fire Spread active: Community testing found this combination increases total Onslaught Stake damage by approximately 22% compared to the base skill. The braid amplifies fire output, and the fire spread’s lingering flame directly benefits from that amplification, turning the ground-fire DoT from a cosmetic effect into a meaningful secondary damage window.
For pure stance damage (not total damage), fire or physical relic bonuses increase the approximately 60 or 120 stance values proportionally. Against Fulghor and Caligo specifically, a strong enough relic setup can push you closer to one charged hit to stagger instead of two — worth testing if your build supports high fire or physical output. For full relic priority breakdowns and which choices matter most per Nightfarer, see our Relic System guide.
How to Use Onslaught Stake by Playstyle
The right approach depends on how deeply you want to optimise. These recommendations reflect genuinely different priorities, not the same advice restated:
| Player Type | Core Priority | Fire When | Hold When |
|---|---|---|---|
| New / Casual | Consistent stagger, simple execution | Boss is grounded after any heavy attack | Gnoster is in split form; boss is below 60% HP and glowing |
| Efficient Optimiser | Gauge economy | To land a killing blow on elites for 75% gauge refund; immediately after confirmed phase transition | If HP transition is imminent; if fire spread relic isn’t deployed and DoT window would be wasted |
| Cooperative Hardcore | Coordinated two-hit stance break on Fulghor / Caligo | Second Wylder fires within 3 seconds of first hit landing; use Caligo Frost Shard cancel as the setup hit | Solo on Fulghor or Caligo without teammate coordination — the gauge cost isn’t justified without the break |
Frequently Asked Questions
Can Onslaught Stake be used in midair?
Yes. Firing midair propels Wylder horizontally in the direction you’re moving — aim backward while jumping and you’ll travel forward while the stake fires behind you. This has a practical non-combat use: extending Wylder’s jump range to reach elevated platform positions or cross gaps. Stance damage is the same regardless of whether you fire from the ground or the air.
Can it revive downed teammates?
Yes. Wylder needs to deal 40 damage to a downed teammate for the first revival bar, or 240 total damage for all three bars. A direct Onslaught Stake hit handles all of that in one blast. The most reliable setup is when a teammate is crawling toward a group of enemies — you eliminate the enemies and trigger the revival simultaneously. Don’t redesign your stagger sequencing around this, but keep it in mind when a teammate goes down mid-boss encounter.
Should I ever fire uncharged instead of charged?
Yes, in two situations: when you need to interrupt a specific dangerous incoming attack and cannot wait for the full charge wind-up, and when you want to retain partial gauge for a rapid second shot in the same stance-damage window. Two consecutive uncharged hits on an easy-tier Nightlord technically cost more total gauge than one charged hit, but the flexibility to keep the gauge partially charged matters when the boss is unpredictably moving or when you need the interrupt immediately.
Does depth scaling change the stagger math?
Based on community reports, stance values scale with depth in a similar way to HP — Depth 5 bosses carry approximately 2.16x their base HP. Stance values appear to scale proportionally, though the exact multiplier hasn’t been confirmed through systematic testing. Treat the table above as a floor: at Depth 3 and above, Fulghor and Caligo may require three charged hits rather than two. The core advice stays the same at any depth — coordinate two-hit sequences on hard-tier bosses with a teammate rather than attempting to solo-stagger them.
