You get the Nightmare Catcher in Blox Fruits by defeating Reborn Skeletons (Lv. 1,975) or Living Zombies (Lv. 2,000) at the Haunted Castle in the Third Sea. This Mythical material has one job: unlocking the Pain fruit’s hidden abilities through the Admin Panel, and you’ll need up to four in total. As of November 2026, farming it takes minutes, not hours.
Here’s everything at a glance:
| Detail | Info |

| Type | Mythical material |

| Dropped by | Reborn Skeleton, Living Zombie |
| Added | Update 27.2 |
| Main use | Upgrading Pain |
| Total needed | 4 |

The Nightmare Catcher is a Mythical material released with Update 27.2 alongside the Pain rework. Unlike boss-exclusive drops, it comes from regular enemies, which is why the Blox Fruits Wiki ranks it the easiest Mythical material to obtain. Its only use is upgrading Pain, so don’t grind for it until you actually own the fruit — spend that time unlocking Third Sea instead.
Nightmare Catchers drop at the Haunted Castle, an island in the Third Sea tucked behind the Castle on the Sea. Two enemies spawn here:
| Enemy | Level | Spawn Spot | Notes |
|---|---|---|---|
| Reborn Skeleton | 1,975 | Graveyard, left of the castle | 7 spawn close together, 15-second respawn |
| Living Zombie | 2,000 | Around the castle | Higher level, hits harder |
I always farm the Reborn Skeletons. They cluster tightly, respawn every 15 seconds, and deal less damage than Zombies, making them ideal for AFK or mastery grinding while you wait on the drop. Bonus: each kill also drops 1–3 Bones.
Buy Pain from the Blox Fruit Dealer for 2,300,000 Beli (or roll Zioles’ gacha), equip it, then visit the Mysterious Scientist at the Castle on the Sea, left of the Set Home Point. Interact to open the Admin Panel, complete each research task, and pay up:
| Ability | Mastery | Research Task | Cost |
|---|---|---|---|
| Torment Conductor | 400 | Defeat a Rumble/Lightning user or Enel | 1 Nightmare Catcher, 6,000 Fragments, 5 Ectoplasm |
| Spectral Assimilation | 500 | Absorb 201 Pain Ghosts | 3 Nightmare Catchers, 9,500 Fragments, 5 Ectoplasm |
Two things most guides skip: both abilities are mastery-locked, so grind Pain to 400 before farming, and the Enel research is trivial — the Thunder God boss in the First Sea counts, no PvP needed. Total outlay: 15,500 Fragments and 10 Ectoplasm across both upgrades.
It upgrades the Pain fruit — one unlocks Torment Conductor, three unlock Spectral Assimilation. That’s its only use.
Four: one for Torment Conductor, three for Spectral Assimilation. They stack to 99, so grab all four in one session.
Gamer Robot hasn’t published exact odds. Community anecdotes range from a handful of kills to longer grinds, but the wiki still calls it the easiest Mythical material to farm.
Buy it from the Blox Fruit Dealer for 2,300,000 Beli, roll it from Zioles’ gacha, or grab it for 2,200 Robux if you’re impatient.
