How To EASILY Get LUCID LEVIATHAN In FISCH Roblox — Unlock the Cultist Lair and reach the Sanctum by completing the lair NPC quests and crafting the Dreamer’s Amulet, then place the required Cthulid offerings at the Sanctum altars to spawn the Leviathan and have your squad hook it together so multiple players can secure Lucid catches for quest turn‑ins and Eidolon Rod progression.​​

Requirements and access

• Finish Cultist Lair questlines to obtain and use the Dreamer’s Amulet; the gate to Sanctum only opens when you’ve completed the lair’s core NPC chains and hold the amulet while interacting with the central door.​​
• If you’re missing the amulet fragment, start Sythra’s lantern quest in the third room of the lair (after Door 2): take Sythra’s candle, re‑ignite all room lanterns, return to Sythra for the fragment, and assemble the Great Dreamer’s Amulet for final gate access.​

Getting to Sanctum

• Enter the Cultist Lair and progress through the rooms by clearing each door’s objective until you reach the final floor named “Sanctum.”​
• At the bottom hub, interact with the central gate while holding the Dreamer’s Amulet equipped to unlock Sanctum; this hand‑held interaction is required.​

Sanctum setup: spawn the Leviathan

• Inside Sanctum you’ll find offering stations that require specific Cthulid variants; the on‑screen plaques show the needed fish types for the ritual.​​
• Offerings showcased include Nova Cthulid, Rainbow Clustered Cthulid, Aurora Cthulid, Purified Cthulid, and Solar Blaze Cthulid; placing all required variants triggers the Leviathan spawn in the central pool.​

Team method (high success)

• Run Sanctum in a group so multiple players can place offerings and hook the Leviathan simultaneously; multiple hooks raise the odds that at least one player lands a Lucid and then repeats the spawn for others.​​
• Use your radar/pings to confirm the spawn, then everyone casts; if someone rolls a duplicate Lucid Leviathan, repeat the ritual so the rest of the squad can secure theirs in the next cycle.​

Catching tips and builds

• Pop global/lobby luck buffs if available and stack personal luck rods/reels to push Lucid odds during the spawn window.​
• Stabilize control with enchants or reels if your rod setup lacks resilience, and be prepared for a heavy fight—high control and late‑bar focus help secure the catch.​

Turning in and rewards

• Lucid Leviathan is used in the Cultist Lair quest chain; after landing a Lucid, deliver it to the quest NPC specified in your current step to advance toward Sanctum completion rewards.​​
• Completing the chain unlocks deeper interactions in Sanctum and keeps the route open for teammates still catching or turning in their Lucids.​

Eidolon Rod notes (related)

• After Sanctum access, the Eidolon Rod is obtained in the Sanctum layer; creator guides show it as an environmental pickup tied to this room rather than a vendor or craft.​​
• Creator testing reports the Eidolon Rod with 100 Lure Speed, 50% Luck, 0.25 Control, 0% Resilience, infinite kg cap, a Phantom mutation chance, and a surge of about +600% progress once the catch bar passes a specific threshold, dramatically speeding the final quarter of a catch.​

Troubleshooting

• If the Sanctum door won’t open, verify you’ve finished all lair questlines and that the Dreamer’s Amulet is equipped when interacting; patch notes and creator reports indicate amulet hand‑in mishaps were fixed so the amulet returns to your inventory.​​
• If the Leviathan doesn’t spawn after offerings, re‑read the altar plaques to confirm the exact Cthulid variants and replace any incorrect fish, then have all players re‑interact to refresh the ritual.​​

Quick step‑by‑step

• Complete Cultist Lair quests and assemble the Dreamer’s Amulet; enter Sanctum by interacting with the central gate while holding it.​
• Place the required Cthulid offerings at Sanctum’s altars (e.g., Nova, Rainbow Clustered, Aurora, Purified, Solar Blaze) to trigger the Leviathan spawn.​
• Squad‑catch the Leviathan until everyone rolls a Lucid, turn it in for the quest, and keep Sanctum open for repeated runs and Eidolon Rod progression.​​
