If you’re building around Onmyo Magic in Nioh 3, you’ll quickly realize that not all spells scale equally. Some offer utility, some offer elemental buildup, but very few deliver consistent, boss-melting damage. The Hellgust Talisman stands out as the most powerful Wind magic currently available, especially for players focusing on Magic scaling and elemental pressure. Once unlocked and properly equipped, it transforms your playstyle into a storm of sustained AoE devastation.

Location of Demon of Obsession in Bakumatsu
To unlock Hellgust, you must progress to the Bakumatsu chapter set in 1864, where one of the key boss encounters becomes available. The Demon of Obsession is accessed by traveling from Mibu Temple to the Abandoned Temple Outskirts, an area that escalates in Yokai density and difficulty. The environment features tight corridors, elevated pathways, and multiple ambush points, making it essential to manage Ki and spacing carefully before reaching the boss arena.

Defeating the Demon of Obsession to unlock Hellgust
The core requirement for unlocking Hellgust is defeating the Demon of Obsession, a highly aggressive Yokai boss known for layered attack strings and elemental pressure. This fight demands strong Ki management and burst timing.
The encounter emphasizes pattern recognition. The boss frequently chains melee swings with area-based elemental surges, forcing you to reposition rather than trade damage. Wind resistance is helpful, but survival depends more on spacing and patience. Once the boss enters its enhanced phase, its aggression increases, and delayed attacks become more common. This is where ranged magic or Soul Core bursts can give you breathing room.

Upon defeating the Demon of Obsession, you receive the Demon of Obsession Soul Core, which is the key component required to activate Hellgust Talismans in their Yin alignment. Without this Soul Core, the spell cannot be used at full capacity.
How Hellgust Talisman works in combat
Once equipped and activated, Hellgust Talisman summons powerful green tornadoes that persist in the battlefield for an extended duration. Unlike instant-cast elemental bursts, Hellgust creates a damage zone that continuously hits enemies caught within its radius.
The spell’s true strength lies in its multi-hit scaling. Each tornado tick applies Wind damage repeatedly, making it devastating against large enemies and bosses with wide hitboxes. Because it remains active for a long time, it allows you to reposition, recover Ki, or chain additional Onmyo spells while the tornado continues dealing damage independently.

The tornado’s duration means you are not forced into constant casting cycles. Instead, you can control space while the spell does the work for you.
Damage scaling and Onmyo synergy
Hellgust scales primarily with your Magic stat, making it ideal for dedicated Onmyo builds. When combined with gear that increases:
- Wind damage
- Onmyo Magic Power
- Elemental accumulation
- Duration extension
the spell’s performance improves significantly.
Below is a simplified damage interaction overview.
| Attribute | Impact on Hellgust |
|---|---|
| Magic | Direct damage scaling |
| Onmyo Power | Boosts spell potency |
| Wind Damage Bonus | Increases elemental output |
| Duration Effects | Extends tornado uptime |
| Elemental Debuffs | Enhances overall DPS |
Because Wind excels at Ki pressure and stagger potential, Hellgust can rapidly deplete enemy Ki when multiple tornado hits connect. Against bosses, this can lead to faster openings for Grapples or Burst Counters.

Why Hellgust is considered the most powerful Wind magic
Several factors contribute to Hellgust’s dominance in the current meta.
First, its sustained damage model outperforms burst-only Wind spells, especially in prolonged fights. Second, its persistent tornadoes allow safe positioning. You can cast once and disengage, letting the spell maintain pressure.
Third, Hellgust synergizes extremely well with Soul Core setups. Since it requires the Demon of Obsession Soul Core in Yin alignment, it fits naturally into builds that emphasize Yokai abilities and magic hybrids. The combination of passive tornado damage and active Soul Core bursts creates layered offensive pressure that overwhelms enemies.

Compared to other Onmyo spells that require repeated casting and heavy anima management, Hellgust offers efficiency and consistency.
Optimizing a Hellgust-centered magic build
To fully leverage Hellgust, you should focus on maximizing Magic investment and Wind amplification. Onmyo capacity should be increased so you can carry multiple Hellgust Talismans per mission. Combining it with Ki regeneration tools ensures you can reposition while tornadoes are active.
Magic-focused armor sets that enhance Onmyo effectiveness further amplify its power. Players running spear or switchglaive weapons often find excellent synergy because they can maintain mid-range pressure while tornadoes chip away at enemy health.

Positioning also matters. Casting Hellgust near walls or choke points increases hit consistency because enemies cannot escape the tornado’s radius easily.
Strategic use in boss encounters
Against large bosses, the tornado’s repeated hit registration results in staggering damage accumulation. The key is casting at the right moment, typically after forcing a recovery animation or when the boss transitions phases.
If used early in a phase, Hellgust can tick for nearly its full duration, maximizing efficiency. Because the tornado remains active independently, you can shift to defensive play or supplement damage with ranged Onmyo attacks.
In Yokai Realm phases, the sustained damage helps offset the natural pressure of reduced Ki recovery, allowing you to maintain offensive momentum without overcommitting.
Reward obtained from defeating the Demon of Obsession
| Reward | Purpose |
|---|---|
| Demon of Obsession Soul Core | Required to activate Hellgust (Yin Position) |
| Standard Boss Loot | Weapons, crafting materials, gear |
| Progression Unlock | Access to Hellgust Talisman capability |
The Soul Core is the critical component. Without equipping and aligning it properly, the Hellgust Talisman cannot be activated in its intended form.
