How to Earn Spooky Tokens for Hellfire Gas
The gacha takes Spooky Tokens, so farming them is the slow part of the process. The Harvest Moon Trick-or-Treat runs for 10 minutes at the top of every hour in all three Seas, which makes it a good event to plan around.
Door minigames and smashing pumpkins in the Jack O' Lantern Hunt also pay tokens, and so do the Hell Rider and Werewolf bosses. Mixing these sources keeps you from waiting on a single timer.
How to Roll Zioles' Spooky Gacha for Hellfire Gas
- Find Zioles.
- Talk to Zioles and choose the Spooky Gacha.
- Spend your tokens on a roll.
Hellfire Gas is the grand prize, so it's the top reward on the gacha. Each roll is a chance at it, and since every roll costs the same tokens, your farming pace decides how many chances you get.

Hellfire Gas Moves and the Mastery Each One Needs
Hellfire Gas uses the same ability keys as Gas, and the table shows the mastery Gas sets for each one. Mastery is the skill level you build by using a fruit.
| Key | Hellfire Gas move | Mastery needed |
|---|---|---|
| Z | Suffocating Fumes | 1 |
| F | Traveling Gas | 50 |
| X | Bursting Vapor | 100 |
| C | Smog Demons | 200 |
| V | Vapor Condensation | 300 |
Z opens at mastery 1, while V waits until 300. Since V is the key that transforms you, 300 is the number to plan your grind around.

Hellfire Gas Moves in Normal Form
In normal form, the keys work like this:
- M1: A fast fiery blade combo with upgraded flame effects.
- Z: Fires a projectile that splits into four pieces partway through its flight.
- X: Tap for an explosion right in front of you. Hold to launch the blast farther, where it explodes on impact.
- C: Tap to fire smog demons instantly. Hold to charge a larger volley.
- F: Teleports you forward in flames and releases small homing fireballs that chase nearby enemies.
- V: Uses a full Hellfire Meter to transform you into the Hellfire Demon.
X and C change with how long you hold them, so a tap gives you a fast option and a hold gives you a bigger one. Practice both, since the better choice depends on the fight.
How the Hellfire Meter Unlocks the Hellfire Demon Form
Hellfire Gas swaps the usual Gas Meter for the Hellfire Meter. It fills over time, and it fills faster when your M1 and abilities hit enemies. Once it's full, press V to transform into the Hellfire Demon.
The Hellfire Demon wields dual flaming chainsaws. The form brings damage reduction, faster movement and dashing, water-walking, and stronger M1s and skills.

Its moves are:
- M1: Bigger, stronger swings with the chainsaws.
- Z: Throws a flaming chainsaw. A miss explodes on the ground, while a direct hit explodes and pulls the target slightly toward you.
- X: Tap for a vertical flame slash that explodes on impact. Hold to spin into a flame tornado that hits repeatedly and knocks enemies back at the end.
- C: Tap for a quick wave of flame demons. Hold for a massive barrage with more range.
- F: Teleports you forward and summons a giant fire skull from the ground that erupts for area damage.
- V: Returns you to normal form.
Start in normal form and keep landing hits until the meter fills, then transform.
