The fastest Hallowed Bar farm is to breed Alpha Eye of Cthulhu from the Sealed Realm of Terraria, boost egg pickup with Broncherry, Broncherry Aqua and Grintale, then hatch and butcher or conveyor the Cthulhus for huge Hallowed Bar drops.
Hallowed Bar arrived with the Tides of Terraria content as the material behind the crossover gear and the Celestial Sigils that summon Moon Lord, and the moment you start crafting at that scale, hand-farming stops working. The route below turns one captured boss into a renewable egg loop, and a single full egg pickup can hand you bars by the thousand.
The fastest Hallowed Bar farm right now
One Eye of Cthulhu is all the seed stock you need. Because any Terraria Pal will breed with it and still produce another Eye of Cthulhu, a single capture in the dungeon becomes an infinite supply, and every egg you pick up by hand has a chance to roll into an Alpha egg. Alpha Eye of Cthulhus drop 20 to 30 Hallowed Bars base, doubled again if they carry Lavish Hospitality.
You’ll also see players farming Rainbow Slimes through a disassembly loop, speedrunning the dungeon boss, or just looting overworld chests. Those work, and they’re worth knowing about further down, but none of them scale the way an Alpha egg farm does once the breeding pair is set up.
What you need before you start
Almost everything here is standard base tech plus three specific Pals, and the three Pals are the part people skip. Their partner skills are what convert an ordinary breeding farm into an Alpha egg machine, and those skills stay switched off until the saddles are built.
| Requirement | Use |
|---|---|
| Sealed Realm of Terraria access | The only place to catch Eye of Cthulhu |
| Eye of Cthulhu | The parent that makes every egg a Cthulhu egg |
| Any opposite-gender Terraria Pal | The second breeding parent |
| Pal Surgery Table | Applies Philanthropist to both parents |
| Normal Breeding Farm | Lets you pick eggs up by hand so partner skills apply |
| Vegetable Cakes | Fuel for breeding, doubles the eggs produced |
| Egg incubators | Hatching the pile at the end |
| Broncherry and Broncherry Aqua | Chance to turn each picked-up egg into an Alpha egg |
| Grintale | 50% chance of an extra egg per pickup |
| All three saddles | Partner skills do nothing without them |
| Pal Disassembly Conveyor | Converting hatched Cthulhus into bars |
How to catch Eye of Cthulhu and build the egg farm in Palworld
The route runs from the dungeon entrance to the boss room, then straight into the breeding and egg-boost setup back at base.
Enter the Sealed Realm of Terraria
The dungeon sits southeast of the Fisherman’s Point travel point on its own island, and it is packed with enemies, so bring a shotgun.
Catch one Terraria Pal of each gender
Literally any Terraria-specific Pal works as the breeding partner, so grab a couple on the way in.
Look for Lavish Hospitality and Service-Minded
Both passives are worth rerolling captures for, but the farm is already strong without either.
Take the first left
Head through the opening tunnel and turn left in the first room.
Go right in the second room
The next chamber up ahead branches, and the right-hand exit is the one you want.
Take the right fork
That tunnel splits shortly after, so stay right.
Turn left in the mushroom cave
The mushroom-lit chamber is the easiest landmark on the route.
Drop down
There’s a ledge here you can simply fall from.
Move behind the wall
Slip around the back of the wall section ahead of you.
Break straight through, then keep going forward.
Break the second wall
One more cuttable wall stands between you and the boss chamber.
Catch the Eye of Cthulhu
This is the whole point of the trip, so land the capture before you leave.
Loot the Celestial Sigil schematic chests
The schematic only matters if you intend to summon Moon Lord, and the recipe only shows up while it is sitting in your inventory.
Put both parents in your party
Add the Eye of Cthulhu and any opposite-gender Terraria Pal, ideally the one carrying Lavish Hospitality.
Give both of them Philanthropist
Head to a Pal Surgery Table and apply the passive to the Cthulhu and its partner.
Assign the pair to the Breeding Farm
Without Lavish Hospitality you are done here and can start breeding immediately.
Breed up two Lavish Hospitality Cthulhus
Keep cycling the pair until both offspring carry it, reapply Philanthropist at the surgery table, and do the same for Service-Minded if you want it.
Skip Nocturnal entirely
Eye of Cthulhu is naturally nocturnal, so the pair keeps working through the night on its own.
Collect Broncherry, Broncherry Aqua and Grintale
Each has its own spawn region on the map, and the two Broncherry stack because the no-stacking rule only blocks duplicates of the same species.
Understand what they do
The Broncherry roll picked-up eggs into Alpha eggs, and Grintale adds a 50% chance of a second egg.
Condense them if you want the ceiling
Four-star condensing pushes each Broncherry to a 45% Alpha roll, with both Broncherry and Broncherry Aqua needed for 100%, and Grintale to 75%.
Unlock and craft all three saddles
Their passives genuinely do not fire until the saddles exist in the technology tree and in your inventory.
Speed the breeding up
Place a Berolah at your base and keep a Pal with the Babysitter trait working the farm.
Feed the farm Vegetable Cakes
These double the eggs the pair produces while the loop runs.
Pick every egg up by hand
With the three boosters in your party you’ll see "mysterious energy enlarges the egg" and pull doubles constantly.
Use a normal Breeding Farm, not an automated one — Broncherry and Grintale’s partner skills only trigger on eggs you physically pick up, so automation quietly deletes the entire Alpha bonus.

Turning hatched Eye of Cthulhus into bars
Hatch the whole batch and sort the Alphas out first, since they’re the ones carrying the 20 to 30 bar payout. From there you have two ways to cash them in, and the gap between them is convenience versus raw output.
| Method | Best for |
|---|---|
| Splat Arena | Maximum bars per Cthulhu, and it scales further when condensed |
| Pal Disassembly Conveyor Belt | Hands-off bulk processing of an entire hatch |
The numbers get silly fast. A single butchered Eye of Cthulhu in an uncondensed Splat Arena has produced 78 Hallowed Bars, and running barely half a batch of eggs through a conveyor returned close to a thousand. With the Broncherry and Grintale fully condensed, a full egg pickup averages around 2,000 Hallowed Bars, though your own totals will swing with Alpha rolls, passives and which processor you use.
Other Hallowed Bar methods players use
The community has landed on a handful of alternatives, and a few of them are genuinely good if you’d rather not build a breeding loop. The Rainbow Slime route in particular gets recommended as the top farm in 1.0, built around breeding slimes with Lavish Hospitality and Service-Minded — worth 100% and 50% extra material drops respectively — then feeding them into a Pal Disassembly Conveyor Belt.
| Method | How it works |
|---|---|
| Rainbow Slime disassembly loop | Breed slimes for drop passives and route them through the conveyor belt |
| Dungeon speedrun | Sprint the Sealed Realm route and kill the boss in roughly 3 to 5 minutes per lap |
| Elphidran on boss kills | Used while killing or capturing the boss to lift the drop count |
| Maxed Katress | Players report 20 to 30 bars per Rainbow Slime killed with one |
| Chests and exploration | Bars appear in overworld chests, but with no repeatable rate |
Butchering bred Eye of Cthulhus has also been reported at around 100 bars a head by players running the breed-and-butcher version, and the slime-and-conveyor loop is the slowest of the bunch to run but the easiest to leave AFK. Chest looting is the one to avoid outright once any farm is standing.
Where Hallowed Bars get spent
Hallowed Bar is described in-game as a sacred material infused with divine energy, and it feeds the whole Terraria-themed crafting tree, from the Hallowed Plate Mail armor down to the smaller crossover pieces.
The real sink is the Celestial Sigil, which costs 100 Hallowed Bars each and summons the Moon Lord raid boss. Since that’s a repeatable summon for stat fruits and endgame rewards, sigils are the reason anyone bothers building a bar farm at all — and why 2,000 bars a cycle stops sounding excessive.
Frequently Asked Questions
Can you farm Hallowed Bars without Lavish Hospitality?
Yes. Lavish Hospitality doubles the bars an Alpha Eye of Cthulhu drops, but the farm runs perfectly well on a plain pair — you can assign them to the Breeding Farm the moment both have Philanthropist and skip the reroll grind entirely.
Do Broncherry and Broncherry Aqua stack for eggs?
They do. The “does not stack” wording on the skill only blocks two Pals of the same species, so you can’t run two Broncherry Aquas, but one of each is a legitimate double dip on the Alpha egg roll.
Why are my Broncherry and Grintale partner skills not working?
The saddles. Each of the three needs its saddle unlocked in the technology tree and actually crafted, otherwise the passive never fires. The other common cause is using an automated breeding setup, since the bonuses only apply to eggs you collect manually.
Do you need Nocturnal on Eye of Cthulhu?
No. It’s naturally nocturnal already, so it keeps working the breeding farm overnight without the passive. Spend those reroll attempts on Lavish Hospitality.
Is Rainbow Slime farming better than Eye of Cthulhu breeding?
Rainbow Slimes are the more popular recommendation and they’re excellent for AFK output, but they’re slower per cycle. If you want the highest burst of bars in one sitting, the Alpha egg pickup wins; if you want something that quietly accumulates while you play, run the slimes.

What are Hallowed Bars used for?
Terraria crossover crafting and Celestial Sigils. If your sigil recipe seems to have disappeared after the dungeon, check your inventory — the recipe only appears while the schematic is being carried, and sigils can be crafted at a Primitive Workbench.
