- Loomian Legacy cosmic raid: The Nightmare Cosmic Jeweltooth is the toughest raid boss challenge currently available.
- Core strategy: Two Goggles Lantorch with Flare strip 2-3 health bars before going down to Earthquake.
- Cleanup crew: Hollybunch and Plasmyth finish the fight, with Square One removing boss stat boosts.
- Average clear time: Roughly 3 minutes with a coordinated partner.
- RNG factor: Earthquake timing matters; Bulk Up or Primal Slash turns give extra Flare windows.
Cosmic Raid Overview and Boss Mechanics
The Loomian Legacy cosmic raid pits you and a partner against Nightmare Cosmic Jeweltooth, a multi-health-bar boss that stacks offensive boosts while punishing your team with wide-hitting moves. Recent raid nerfs opened the door to a much faster clear than the older tank-and-grind approaches, making aggressive Fire-type openers the new meta.
Understanding the boss's move pool is the difference between a 3-minute clear and a wipe. Earthquake is the punishing threat that ends your Lantorch run early, while Bulk Up and Primal Slash give you free turns to keep attacking.
Video Highlights:
- Goggles Lantorch with Flare takes down a full health bar per use
- The set survives one Earthquake, guaranteeing two Flares
- Two Lantorches strip 2-3 bars before falling
- Hollybunch and Plasmyth clean up late game
- Full raid clear takes about 3 minutes on average
| Boss Move | Threat Level | Effect on Your Strategy |
|---|---|---|
| Earthquake | ★★★★★ | Ends Lantorch run; the main loss condition |
| Bulk Up | ★★ | Free turn to land another Flare |
| Primal Slash | ★★★ | Survivable damage; keep attacking |
| Thunderclap | ★★★ | Can pick off weakened Lantorches |
| Stat stacking | ★★★★ | Requires Square One from Plasmyth to reset |
Nightmare Cosmic Jeweltooth stacks attack and range defense boosts over the fight. If you ignore them, late-game damage falls off hard. Always save Square One on Plasmyth for the moment the boss has multiple boosts stacked.
The Dual Lantorch Flare Strategy
The strategy revolves around Goggles Lantorch running Flare. Goggles improves consistency, and the build is tuned to survive exactly one Earthquake, which guarantees at least two Flare activations. Each Flare reliably removes one full health bar, sometimes more with favorable RNG.
Running two Lantorches means the opening phase strips 2-3 bars before either player's opener goes down. After the boss breaks through, you transition into the cleanup phase with Hollybunch and Plasmyth.
Goggles Lantorch (Opener)
- Flare removes ~1 health bar per use
- Survives one Earthquake
- Guaranteed 2 Flares per Lantorch
Hollybunch (Mid Game)
- Comes in after first Lantorch falls
- Keeps offensive pressure with Flare
- Can also support with Nova Blast chip damage
Plasmyth (Closer)
- Square One erases boss stat boosts
- Nova Blast finishes the final bars
- Best held back until boosts stack
| Phase | Loomian on Field | Goal | Risk |
|---|---|---|---|
| Opening | Lantorch x2 | Flare turns 1-2, strip 2-3 bars | Early Earthquake |
| Mid game | Hollybunch | Break tank bars, keep pressure | Thunderclap snipes |
| Closing | Plasmyth | Square One reset, Nova Blast kill | Boosted boss damage |
Click Flare on turn one without hesitation. Every non-Earthquake turn the boss takes is free damage you should never pass up. Hesitating on Bulk Up or Primal Slash turns is the most common reason clears run long.
Step-by-Step Raid Execution
Turn One: Open with Flare
Both players lead Goggles Lantorch and immediately click Flare. This guarantees one to two health bars down before the boss responds, regardless of what it picks.
Turn Two: Push for a Second Flare
If the boss uses Bulk Up or Primal Slash instead of Earthquake, both Lantorches fire a second Flare, stripping up to three or four total bars.
Transition to Hollybunch
Once Lantorches fall to Earthquake or Thunderclap, bring in Hollybunch to maintain Flare pressure and chip the remaining tank bars with Nova Blast support.
Send in Plasmyth
When the boss has stacked multiple boosts, bring Plasmyth in and use Square One to reset its stats, breaking the range defense wall.
Close with Nova Blast
Finish the fight with Nova Blast from Hollybunch and Plasmyth. Clean runs complete in roughly 3 minutes.
Time your Plasmyth entry with your partner. Ideally one player's Lantorch falls while the other still pressures, so Square One lands when boosts are stacked but before the boss snowballs out of control.
Team Building and Preparation Checklist
| Requirement | Details | Priority |
|---|---|---|
| Goggles Lantorch | Fire opener with Flare, survives one Earthquake | ★★★★★ |
| Second Lantorch | Partner runs the same opener build | ★★★★★ |
| Hollybunch | Mid-game Flare pressure and Nova Blast | ★★★★ |
| Plasmyth | Square One support and closer | ★★★★ |
| Raid partner | Two-player coordination required | ★★★★★ |
| Backup openers | Optional extra Fire attackers for bad RNG | ★★ |
Before You Queue the Raid:
- Level and train two Goggles Lantorch with Flare
- Prepare Hollybunch with Flare and Nova Blast coverage
- Teach Plasmyth Square One for boost resets
- Coordinate phase transitions with your raid partner
- Review the boss move pool to read Earthquake risks
Average clears land around 3 minutes. Runs slightly faster or slower are normal and usually come down to how early the boss clicks Earthquake versus Bulk Up. A four-bar opening is possible but never something to plan around.
Common Mistakes and Troubleshooting
| Mistake | Consequence | Fix |
|---|---|---|
| Saving Flare for later | Wasted free turns | Always Flare turn one |
| Plasmyth enters too early | Square One wasted, no boosts to reset | Wait for stacked boosts |
| No second Lantorch | Only 1-2 bars stripped before cleanup | Both players run the opener |
| Ignoring range defense buffs | Late damage falls off | Time Square One before closing |
| Panicking on Primal Slash | Unnecessary switches | It is survivable; keep attacking |
If your Lantorch is low and the boss has boosts stacked, letting it fall on purpose to bring Plasmyth in is often correct. The reset is worth more than one extra Flare.
Cosmic Raid FAQ
Q: How long does the Loomian Legacy cosmic raid take with this strategy?
A coordinated pair running dual Goggles Lantorch clears the Nightmare Cosmic Jeweltooth raid in about 3 minutes on average. Slight variations come from RNG, mainly how early the boss uses Earthquake.
Q: Why does Lantorch only get two Flares?
The Goggles Lantorch build is tuned to survive exactly one Earthquake. That survivability window guarantees two Flare activations, each removing roughly a full health bar before it goes down.
Q: What does Square One do in this raid?
Square One, used by Plasmyth, resets the boss's stat boosts. Nightmare Cosmic Jeweltooth stacks attack and range defense buffs throughout the fight, and removing them restores your late-game damage output for the Nova Blast finish.
Q: Can this strategy be run solo?
The strategy is designed for two players. The two-Lantorch opening is what strips 2-3 bars quickly, so solo players will need a slower, more defensive team built around sustained healing and boost management.
