The Kuku Marni Laser Helm turns a defensive slot into an offensive tool, firing a locked-on energy beam with three charges and multi-target lockon once you forge the upgraded version. Crafting it requires two separate blueprints, a base Marni Laser Helm pickup, and a stack of cores and components pulled from sanctums, caves, and Delesyia's mech patrols.
Materials checklist
| Material | Qty | Where to get it |
|---|---|---|
| Marni Laser Helm (base) | 1 | Castle ruins in southern Delesyia, near Mount Beave |
| Enhanced Kuku Pot | 1 | Crafted at Grimnir's Kuku Shop (1 Kuku Pot + 1 Abyss Cell) |
| Kuku Marni Laser Helm blueprint | 1 | Sanctum of Benediction (Hernand) |
| Enhanced Kuku Pot blueprint | 1 | Sanctum of Absolution (Hernand, near Mountain of Frozen Souls) |
| Core of Transgression | 1 | Sanctum of Oblation puzzle (island east of Delesyia) |
| Power Core - Gate of Collapse | 1 | Stone worm in Anvil Hill Cave (Demeniss) |
| Electrical Component | 3 | Medium combat mechatanks in Delesyia (Eastern Hills) |
| Abyss Cell | 1 | Debris pile near Drakefall Gorge / Drakesfall Castle (Hernand) |
You also need a base Kuku Pot. If you do not have one, craft it from 5 Iron Ore and 5 Timber at Grimnir's Kuku Shop in Hernand. The pot itself unlocks through the witch questline and a faction quest tied to Marek in Blackstar (Delesyia).
Pick up the base Marni Laser Helm
The base helm sits inside a ruined castle in the southern reaches of Delesyia, south of Mount Beave. Wyverns patrol overhead but ignore you. The ground-level mechs and flying mosquitoes will aggro, so plan a stamina-conscious sprint.
Step 1: Travel to the Delesyia coastal castle south of Mount Beave. Cross the water and run past the mechs guarding the entrance rather than fighting them.
Step 2: Inside the main gate, loop left along the primary pathway and keep moving. Stop briefly to recover stamina between enemy clusters so you do not get pinned.
Step 3: After passing through an inner gate, turn left and look for a circular archway with a large enemy inside. The helm sits on the floor in a pile of gears behind it. Kill or shake aggro from any nearby mechs and mosquitoes (one bow shot kills the mosquitoes), then interact to pick up "Marni Laser Helm".
Restore the Sanctum of Benediction for the helm blueprint
The Kuku Marni Laser Helm blueprint comes from the Sanctum of Benediction, located in the western snowy mountains of Hernand. The closest fast travel is the Abyss Nexus at Starlight Storm Cave.
Step 1: Clear the Antumbra soldiers around the sanctum so the area is liberated. The puzzle cannot be solved while enemies are active.
Step 2: Collect the first Fusion Reactor Core from the southwestern entrance inside the sanctum. Light the stone lantern to the right of the tower entrance to unlock the door, then grab the second core inside.
Step 3: Install the round-top core on the broken pillar using Aerial Force Palm, then insert the cube-shaped core into the central machine with a regular Force Palm. The structure activates, and "Blueprint II: Kuku Marni Laser Helm" is added to your knowledge.
Restore the Sanctum of Absolution for the Enhanced Kuku Pot blueprint
The upgraded helm requires the Enhanced Kuku Pot, which needs its own blueprint from the Sanctum of Absolution near the Mountain of Frozen Souls in Hernand.
Step 1: Travel to the Sanctum of Absolution and clear the area. Speak with the witch Elowen on site.
Step 2: Complete the cleansing interaction. The "Sanctum of Absolution" quest closes, and "Blueprint I: Enhanced Kuku Pot" is awarded.
Get the Core of Transgression from Lyselia's sanctum
The Core of Transgression drops from a sanctum tied to Lyselia, the Witch of Humility. You must unlock her first, or her cave and sanctum interactions stay locked.
Step 1: Travel north of Hernand to the broken bridge where a person hangs over the edge. Help them up. The cutscene reveals Lyselia in disguise, and her cave in the Serpent Marsh (south of Demeniss) becomes accessible.
Step 2: Head to the Sanctum of Oblation on an island off the eastern coast of Delesyia. Clear the enemies and speak with Lyselia to register the sanctum as restored.
Step 3: Solve the kiln light puzzle on the central structure. Use Blinding Light (both bumpers, then tap L1) to ignite each notch as it aligns with the glowing crystal. A mistimed input resets the notches to orange, and you start over.
Step 4: When the puzzle completes, a black cube drops from the sky. Shoot it with an arrow, then collect the dropped item to obtain the Core of Transgression.
Farm the Power Core - Gate of Collapse
This power core drops from stone worms inside Anvil Hill Cave in the Demeniss region. The drop is not guaranteed, so a manual save before the fight saves time.
Step 1: Make a manual save, then travel to Anvil Hill and drop into the cave entrance. The drop is one-way.
Step 2: Defeat the stone worms inside. One worm typically drops a Power Core - Spire of Defiance, and another drops the Power Core - Gate of Collapse. Shoot the floating orb each worm leaves behind to release the core, then collect it.
Step 3: If neither worm drops Gate of Collapse, reload the save and retry until it appears.
Farm Electrical Components and the Abyss Cell
You need three Electrical Components and one Abyss Cell. Only the larger mechs drop the components. Smaller humanoid machines do not.
Step 1: Head to the Eastern Hills area in Delesyia (or the roads through the surrounding islands) and locate medium combat mechatanks. After the kill, the mech shakes and explodes, leaving a component on the ground. Pick it up and seal it in your Kuku Pot. Repeat until you have three.
Step 2: Travel to Drakefall Gorge in Hernand and approach the ruined Drakesfall Castle. Destroy the metallic, crystalline debris pile and pick up the Abyss Cell.
Craft the Enhanced Kuku Pot, then the helm
Both crafts happen at Grimnir's Kuku Shop in Hernand. Speak with Grimnir to open the Kuku Item Crafting and Enhancement menu.
Step 1: Select the Enhanced Kuku Pot node. The recipe needs 1 Kuku Pot and 1 Abyss Cell. Craft it. The notification "Enhanced Kuku Pot acquired" confirms the upgrade.
Step 2: Select the Kuku Marni Laser Helm node. The required materials list reads:
| Material | Qty |
|---|---|
| Enhanced Kuku Pot | 1 |
| Marni Laser Helm | 1 |
| Power Core - Gate of Collapse | 1 |
| Electrical Component | 3 |
| Core of Transgression | 1 |
Step 3: Confirm the craft. The notification "Kuku Marni Laser Helm acquired" closes the loop. The helm now sits in your equipment, ready to refine at any blacksmith.
How the upgraded helm differs from the base version
| Feature | Marni Laser Helm | Kuku Marni Laser Helm |
|---|---|---|
| Laser charges | 1 | 3 |
| Multi-target lockon | No | Yes |
| Refinable at blacksmith | No | Yes |
| Special effect | Daze Immunity | Daze Immunity |
| Activation | L2 + R2 (LT + RT) | L2 + R2 (LT + RT) |
| Cooldown | 60 seconds | 60 seconds per charge cycle |
Lock onto a target before pressing the activation input. Without a lock, the beam does not fire. The Kuku version's three charges and multi-target lockon make it viable for clearing groups, while the base version is a single-shot opener that cannot be refined past its baseline defense.
Common reasons the craft does not trigger
- You crafted the standard Kuku Pot but skipped the Enhanced Kuku Pot. The helm recipe will not accept the base pot.
- You picked up a Power Core - Spire of Defiance instead of Gate of Collapse. Only Gate of Collapse satisfies the recipe.
- Lyselia's sanctum puzzle was abandoned mid-sequence. The kiln resets to orange notches, and the Core of Transgression will not eject until every notch is lit cleanly.
- The base Marni Laser Helm is still sitting in the Delesyia castle. The crafting menu requires it as a consumed input.
Once everything is in the menu, the recipe will not gate behind any further quest progress. Reinforce the helm at any blacksmith afterward to push its defense and laser scaling toward endgame values.
