How to Get the Flame Cauldron and What It Boosts

The Flame Cauldron is a level 21 base structure that permanently speeds up every Kindling job your Pals do — furnaces, cooking pots, kitchens, the lot — for a one-off cost of 20 Ingot, 30 Wood and 5 Flame Organ. This guide covers the unlock, the full build bill traced back to raw ore, all 17 structures the boost actually touches, the Kindling Pals worth pairing with it, and how it compares to the nine other work speed boosters in the build menu.

Flame Cauldron at a Glance

It lives in the Other tab of the build menu, next to the rest of the work speed props rather than with the production benches. Two things define it. First, it is a passive aura, not a workstation — nobody staffs it, you just drop it inside your base radius and every Kindling Pal on the property works faster from that moment on. Second, it does not stack: the in-game description spells out that placing more than one has no additional effect, so a second cauldron is 20 Ingot set on fire for nothing.

How to Unlock the Flame Cauldron

The unlock is about as painless as they come: hit character level 21, open the Technology screen, and spend 2 Technology Points on the Flame Cauldron node. There is no boss kill behind it, no schematic to find and no Ancient Technology Point involved. If you are short on points, remember that Alpha Pals and dungeon bosses hand them out on first kill — the full list is in How to Get More Technology Points.

Flame Cauldron Materials and Total Cost

Only three lines on the build panel, and just one of them is crafted. The Ingot is the part that costs you real time — 2 Ore go into every bar, so the 20 on the panel is 40 Ore and 20,000 workload of furnace time on top. Wood and Flame Organ are both gather-and-go, which means the whole build is realistically a single afternoon at level 21 rather than a project.

Material	Qty	Where it comes from
Ingot	20	Primitive Furnace — 2 Ore per bar, so 40 Ore total
Wood	30	4,654 lumber nodes on the map, or a Lumbering Pal at base
Flame Organ	5	Drops from 37 Fire Pals, or 300 Gold each at four shop families

Traced all the way back, one Flame Cauldron is 40 Ore, 30 Wood and 5 Flame Organ. Ore is the only line with any friction attached, and there are 1,632 copper ore nodes marked on the map, so a base parked on a cluster of them covers this build and the next dozen without you swinging a pickaxe. If you are impatient, buying the Flame Organ outright from a wandering merchant runs 1,500 Gold for all five.

Where to Get Flame Organ Fast

Thirty-seven Pals drop Flame Organ and every one of them drops it on a 100% roll, so this is a volume problem rather than a luck problem. At level 21 you do not need the big numbers — Rooby and Flambelle both give 2-3 per kill and between them cover 366 spawn spots across the map, which is two or three kills for the whole build. The better long-term answer is the Ranch: Rooby, Flambelle and Kelpsea Ignis all produce Flame Organ passively there, so one of them parked on a ranch means you never farm this material again. Save Blazamut and Suzaku for when you need Flame Organ in the hundreds for late-game furnaces.

Pal	Flame Organ	Spawn spots	Why bring it
Rooby	2-3	134	The level 21 answer — common, weak, and it also produces Flame Organ on a ranch
Flambelle	2-3	232	Most spawn spots of any easy Fire Pal, and another ranch producer
Kelpsea Ignis	1	786	Only 1 per kill, but 786 spots means you trip over them — best ranch pick by availability
Foxparks	1-2	94	The one you already caught in the first hour; Kindling Lv. 1 as well
Ragnahawk	5-7	150	Best rate you can realistically fight in the 20s, and a flying mount on top
Reptyro	5-7	22	5-7 a kill in Mount Obsidian once you are geared for the volcano
Suzaku	5-10	13	Highest ceiling in the game at 10 per kill, but only 13 spots to hunt
Blazamut	10	16	A flat 10 every time, no roll — the farm target when you need hundreds

Ingot and Wood

The 20 Ingot is the only crafted line, and it is worth pointing out that this build is one of the reasons to get a Primitive Furnace up early even if you have not needed Ingot for weapons yet. Wood is the free part — 30 is nothing once a Lumbering Pal is working, and there are more lumber nodes on the map than any other resource except plain rock. If Ore is your bottleneck, the setup advice in How to Farm Ore is the fix: a second base on an ore cluster with Mining Pals turns 40 Ore from a chore into something already in the chest.

What the Flame Cauldron Speeds Up

"Fire-making speed" is the game's phrasing for the Kindling work suitability, and Kindling covers far more than the furnace most players associate it with. Seventeen structures ask a Pal for Kindling, and the cauldron's boost applies to all of them at once — every furnace tier, every cooking station, both heaters and the whole lighting set. Pocketpair has never published the exact multiplier, so treat the effect as a meaningful percentage bump rather than a number you can plan around, but the direction is not in doubt and it applies for the rest of the save.

In practice, the two places you will feel it are smelting and cooking. Ingot is the spine of every crafting recipe from level 10 onward, and food is the thing that keeps SAN from cratering in a busy base — both of those queues are Kindling-gated, and both get faster the moment the cauldron goes down. The lighting entries are still Kindling jobs, but a Pal lighting a Wall Torch finishes instantly either way, so the boost is invisible there.

Structure	Tech	What Kindling does there
Campfire	2	Cooks your first meals and roasts berries — the earliest Kindling job in the game
Primitive Furnace	10	Smelts Ingot and Charcoal — the queue you run most
Cooking Pot	17	The real kitchen: proper dishes, SAN recovery and buff food
Heater	17	Keeps the base warm at night so your Pals stop losing SAN to cold
Improved Furnace	34	Adds Refined Ingot to the smelting list
Electric Kitchen	41	Faster cooking, but draws 50 power
Electric Heater	41	Wider warmth radius for 100 power
Electric Furnace	44	Unlocks Pal Metal Ingot and Plasteel; 500 power
Large-Scale Stone Oven	49	The big cooking bench for feeding a full base
Gigantic Furnace	58	The late-game smelter — see How to Get the Gigantic Furnace
Mounted Torch	6	Lighting. Kindling lights it, but the job is over in a second
Brick Fireplace	8	Decorative warmth — same instant-job caveat

Best Kindling Pals to Put Under It

The cauldron multiplies what your Pals already do, so it is worth being honest that the Pal matters more than the building. Forty-four Pals have Kindling and the scale runs from Lv. 1 to Lv. 8, which is an eightfold spread before any structure bonus enters the picture — upgrading from Foxparks to a Lv. 7 worker is a far bigger win than the cauldron itself. Renjishi sits alone at Kindling Lv. 8 and has no ordinary spawns at all, only an Alpha, so realistically your ceiling for a long while is the Lv. 7 tier. Of those, Dupin and Flaracle are the ones to chase — both medium-sized, so they fit a crowded base where Jormuntide Ignis eats half your floor space for the same output.

At level 21 none of that is available yet, and that is fine. Arsox at Kindling Lv. 3 is the realistic pick for this stage — 108 spawn spots, medium size, and it doubles as an early mount. Ragnahawk at Lv. 4 is the upgrade to aim for, since it flies and drops 5-7 Flame Organ whenever you need more. Build the cauldron now, and it keeps paying out as you climb this table.

Pal	Kindling	Size	Spawn spots	Why bring it
Renjishi	Lv. 8	L	Alpha only	The only Lv. 8 Kindling Pal in the game — nothing clears a smelting queue faster
Dupin	Lv. 7	M	81	Top-tier Kindling in a medium body, and the easiest Lv. 7 to actually find
Flaracle	Lv. 7	M	26	Same Lv. 7 output plus Handiwork Lv. 6 — a genuine two-job worker
Jormuntide Ignis	Lv. 7	XL	21	Lv. 7 Kindling, but XL and nothing else — only worth it if fire is the base's whole job
Blazamut	Lv. 6	XL	16	Lv. 6 Kindling and Mining Lv. 7, so it covers the Ore side of your Ingot chain too
Faleris	Lv. 6	L	47	Lv. 6 Kindling and a flying mount, so it earns its slot outside the base as well
Ragnahawk	Lv. 4	L	150	The mid-game pick: mountable, common, and 5-7 Flame Organ per kill
Arsox	Lv. 3	M	108	The level 21 pick — easy to catch, rideable, and triple a Foxparks' output
Foxparks	Lv. 1	XS	94	The floor. Fine as a placeholder, but replace it the moment anything better shows up

All 10 Work Speed Boosters and Where the Cauldron Ranks

The Flame Cauldron is not a one-off — it belongs to a family of ten placeable structures that each buff one work suitability, and every single one of them costs exactly 2 Technology Points. Two suitabilities have no booster at all: Transporting and Farming get nothing, so no amount of base decorating will speed up your haulers or your Ranch. The cauldron is the second-earliest of the ten, one level behind the Large Toolbox, which makes it one of the first genuinely permanent upgrades a base can get.

If you are budgeting points, the order below is roughly the order they become worth building. The Large Toolbox and Flame Cauldron are the two that matter in the 20s because Handiwork and Kindling are where almost all early base time goes. The Water Fountain and Silo pay off once you have crops running, the Stump and Axe and Mining Cart once you are feeding a furnace at scale, and the Electric Pylon is a level 48 luxury you build long after the generator is up. Every one of them shares the same no-stacking rule, so one of each is the whole shopping list — the Work Optimizer will tell you which suitability your base is actually short on.

Structure	Work boosted	Tech	Materials
Large Toolbox	Handiwork	20	10 Ingot, 50 Wood, 15 Nail
Flame Cauldron	Kindling	21	20 Ingot, 30 Wood, 5 Flame Organ
Water Fountain	Watering	23	20 Ingot, 50 Stone, 8 Aquatic Pal Fluids
Flower Bed	Gathering	24	30 Wood, 50 Stone, 20 Cement, 10 Beautiful Flower
Silo	Planting	25	30 Wood, 20 Stone, 30 Fiber, 10 Cement
Stump and Axe	Lumbering	28	50 Wood, 10 Ingot, 30 Stone
Mining Cart	Mining	30	20 Wood, 50 Stone, 15 Ingot
Witch Cauldron	Medicine Production	32	10 Ingot, 20 Stone, 5 Cryogenic Coolant, 3 High Quality Pal Oil
Snowman	Cooling	33	5 Ice Organ, 10 Wood, 5 Cloth
Electric Pylon	Generating Electricity	48	20 Ingot, 2 Bio Battery, 5 Circuit Board

Is the Flame Cauldron Worth It?

Yes, and it is close to the easiest yes in the level 20 tech tree. Two Technology Points and 40 Ore buy you a permanent boost to a work type you will still be leaning on at level 60, applied across 17 structures, with no power cost and no worker slot spent. The only wrong way to build it is to build two, or to build it in a base with nobody on Kindling. Just do not expect it to substitute for the Pal — a Flame Cauldron over a Foxparks is still slower than a bare furnace with a Lv. 7 Kindling Pal in front of it. Get both.

Summary

Reach level 21, spend 2 Technology Points, and pay 20 Ingot, 30 Wood and 5 Flame Organ — about 40 Ore once you trace the Ingot back. Drop it in the middle of your furnace-and-kitchen block, keep the best Kindling Pal you own working nearby, and never place a second one. It is one of ten work speed boosters that all cost 2 points each, and alongside the Large Toolbox it is the one worth unlocking first.
