The Sealed Realm of Terraria is Palworld’s full Terraria crossover dungeon, added in version 0.6.0 on June 25, 2025. Reach its small island from Fisherman’s Point, catch 11 Terraria creatures (the six slime colors count separately), collect Hallowed Bars and crossover schematics from dungeon containers and breakable walls, defeat Eye of Cthulhu, and use the Celestial Sigil route to unlock Moon Lord encounters.
Where is the Sealed Realm of Terraria?
The dungeon is on a small island off the coast near Fisherman’s Point. Current map data places the destination at approximately (-421, -789). Guides show slightly different pins—PC Gamer lists (-421, -786), while another entrance marker is around (-423, -796)—so treat those coordinates as an island-area reference rather than a single exact doorway.
| Navigation point | Approximate coordinates | How to use it |
|---|---|---|
| Fisherman’s Point | (-480, -755) | Closest fast-travel anchor reported for the dungeon |
| Sealed Realm island | (-421, -789) | Current data-area marker; nearby guides vary by a few coordinates |
| Alternative entrance marker | (-423, -796) | Approximate waypoint for the island entrance |
Fastest route from Fisherman’s Point
- Fast travel to Fisherman’s Point at approximately (-480, -755).
- Face southeast toward the small offshore island.
- Use a flying or swimming Pal to cross the water. A flying Pal usually gives the clearest view of the island and avoids stamina loss from a long swim.
- Look for the glowing blue entrance or statue. Enter it to load the Sealed Realm dungeon.
Around level 45 is commonly recommended for the dungeon. That recommendation is a preparation guide, not an entry requirement; your actual survivability depends on your armor, weapons, healing supplies and team composition.
What the Sealed Realm contains
This is a complete dungeon route rather than a one-room boss arena. You can explore combat areas, side rooms and structures, open containers, break environmental objects, capture crossover creatures and reach Eye of Cthulhu at the endpoint. The dungeon launched with the Tides of Terraria crossover in version 0.6.0 and remains represented in current 1.0 data pages.
Terraria entities are described as catchable and usable like Pals, but they are best understood as a separate crossover roster rather than ordinary Palpedia entries. In practical terms, you can capture them, add them to your collection and use them as Pal-like companions while progressing through the Terraria content.
Catchable Terraria monsters and completion checklist
There are 11 catchable Terraria monsters. The six slime colors are separate catches, so capturing one slime does not complete the other color entries.
| Creature | Collection note |
|---|---|
| Eye of Cthulhu | Catchable crossover boss creature and dungeon endpoint |
| Demon Eye | Flying Terraria crossover creature |
| Green Slime | Counts as its own slime entry |
| Blue Slime | Counts as its own slime entry |
| Illuminant Slime | Counts as its own slime entry |
| Purple Slime | Counts as its own slime entry |
| Rainbow Slime | Counts as its own slime entry |
| Red Slime | Counts as its own slime entry |
| Enchanted Sword | Catchable crossover entity |
| Cave Bat | Flying cave creature |
| Illuminant Bat | Flying crossover creature |
How to finish the catch collection efficiently
- Run the entire dungeon instead of leaving after the first room; different rooms and encounter groups can contain different entries.
- Keep capture supplies ready before entering. A missed capture can force another full run if the creature does not reappear in the same route.
- Track the six slime colors individually. “All slimes” is not one collection slot.
- Check the endpoint after clearing the route because Eye of Cthulhu is both a boss encounter and one of the 11 catchable entries.
Where to find Hallowed Bars and Terraria blueprints
The Sealed Realm’s loot is distributed through exploration rather than a single guaranteed chest. Search chests, pots, cabins and breakable yellow walls. These objects can provide Hallowed Bars and crossover schematics, so a speed-run that only visits the boss door can miss much of the dungeon’s crafting value.
Container-by-container search order
- Open every chest. Chests are one of the principal sources of crossover schematics and may contain Hallowed Bars.
- Break pots. Small containers are easy to overlook in side rooms and cabins.
- Inspect cabins. Enter each structure and check its interior rather than treating cabins as scenery.
- Strike yellow walls. Breakable yellow wall sections conceal additional loot; scan room edges and dead ends for them.
- Clear the route before resetting. A full-clear loop gives more opportunities for bars and schematics than repeatedly rushing only to the entrance or endpoint.
Hallowed Bars are the central material for the Moon Lord progression. Save a reserve instead of spending every bar immediately on the first available weapon, especially if you intend to repeat summons.
Terraria crossover weapons and armor schematics
The crossover loot pool includes weapon and armor schematics. Reported weapons are:
| Weapon or schematic | How it fits the crossover progression |
|---|---|
| Meowmere | Terraria crossover weapon schematic |
| Excalibur | Terraria crossover weapon schematic |
| Terra Blade | Terraria crossover weapon schematic; also listed among Moon Lord rewards |
| Terraprisma | Terraria crossover weapon schematic |
| Vortex Beater | Terraria crossover weapon schematic; also listed among Moon Lord rewards |
| Nightglow | Terraria crossover weapon schematic; also listed among Moon Lord rewards |
| Legendary Meowmere | Linked to Moon Lord rewards rather than ordinary dungeon-container farming |
Armor schematics are also available, including Hallowed armor. Because the dungeon can award both materials and schematics, a useful farming goal is to clear every loot location first, then decide whether to spend the resulting bars on equipment or reserve them for Celestial Sigils.
Eye of Cthulhu: the dungeon endpoint
Eye of Cthulhu is the Sealed Realm’s endpoint encounter. It is also listed among the catchable crossover creatures, making the final room relevant to both boss progression and collection completion. Prepare for the fight before entering the last area: healing items, repaired equipment and a team that can handle a sustained boss battle matter more than simply meeting the reported level-45 recommendation for the dungeon.
After the encounter, continue checking the surrounding reward area. Dungeon completion and Moon Lord progression are related but not identical: Eye of Cthulhu is the endpoint, while Moon Lord requires a separate summon item and altar.
How to get the Celestial Sigil schematic
The Celestial Sigil Schematic is found as part of the Sealed Realm’s crossover loot. Search chests, pots, cabins and breakable yellow walls during full clears; do not assume that defeating Eye of Cthulhu alone guarantees the schematic. Once you have obtained it, the schematic unlocks the crafting step for the Moon Lord route.
Crafting the Celestial Sigil
- Acquire the Celestial Sigil Schematic through Sealed Realm exploration and loot.
- Collect 100 Hallowed Bars. This recipe requirement is listed for the current 1.0 guide data.
- Use a High Quality Workbench to craft the Celestial Sigil.
- Carry the finished Sigil to a Summoning Altar for the Moon Lord encounter.
The 100-bar cost makes Hallowed Bar farming the limiting step for repeated Moon Lord attempts. If your immediate goal is a first clear, craft one Sigil when you reach the total. If your goal is repeated schematic farming, keep running the dungeon and accumulate bars before converting them into summons.
How to summon and fight Moon Lord
Moon Lord is not summoned directly from the Sealed Realm entrance. The route is:
- Find the Celestial Sigil Schematic in the dungeon’s loot.
- Craft a Celestial Sigil from 100 Hallowed Bars at a High Quality Workbench.
- Offer the Celestial Sigil at a Summoning Altar.
- Choose the encounter difficulty available to your progression and defeat Moon Lord for the crossover reward pool.
| Encounter | Reported level | Reported reward chances |
|---|---|---|
| Normal Moon Lord | Level 50 | Legendary Meowmere 22%; Terra Blade schematic 25%; Vortex Beater schematic 25%; Nightglow schematic 2 25%; Moon Lord Mask 10% |
| Master Moon Lord | Level 80 | Specific chances not stated in the cited current guide data |
The percentages above are the normal-encounter chances listed by PalWorld Calc, not guarantees. The three 25% schematic entries are separate outcomes, and the 22% Legendary Meowmere and 10% Moon Lord Mask entries are likewise individual chances. Repeated summons are therefore part of the expected path if you want every listed reward.
Choosing a farming approach
| Goal | Recommended approach | Trade-off |
|---|---|---|
| Reach the boss quickly | Travel from Fisherman’s Point with a flying Pal, follow the blue entrance and prioritize the main route | Fewer containers checked means fewer bars and schematic opportunities |
| Complete all 11 catches | Run the full dungeon, inspect side rooms and cabins, and record each slime color separately | Longer runs, but less chance of missing a color or crossover creature |
| Farm blueprints and Hallowed Bars | Break yellow walls, smash pots, search cabins and open every chest before resetting | Slower than a boss rush, but maximizes material and schematic rolls |
| Farm Moon Lord rewards | Reserve 100-bar batches for Celestial Sigils and repeat altar summons | Immediate weapon crafting is delayed while bars are saved for summons |
| Attempt Master difficulty | Prepare for the level-80 Master encounter after learning the level-50 normal fight | Higher stated level and greater preparation demand; the cited guide does not state Master drop percentages |
Common mistakes and fixes
Searching for an exact coordinate
Coordinate pins differ by a few points between guides. Use Fisherman’s Point as the reliable travel anchor, then search the nearby island around (-421, -789) for the glowing blue entrance instead of expecting every map marker to match exactly.
Assuming the dungeon is a single boss room
The Sealed Realm is a full dungeon. Skipping side rooms, cabins, pots and yellow walls can cost you Hallowed Bars, armor schematics and the Celestial Sigil Schematic.
Counting slimes as one catch
Green, Blue, Illuminant, Purple, Rainbow and Red Slime are six separate entries. Keep a checklist so a completed slime encounter does not create a false impression that the entire slime set is complete.
Spending bars before planning summons
Celestial Sigils require 100 Hallowed Bars each. If Moon Lord farming is your priority, calculate the bars needed for the number of summons you want before crafting optional equipment.
Expecting every Moon Lord reward on one attempt
The normal encounter has separate listed chances for Legendary Meowmere, three weapon schematics and the Moon Lord Mask. These are chance-based outcomes, so a single victory does not ensure a complete reward set.
