Enter quantities manually. Each number represents individual monsters in your team or storage. The guide does not read your game save.
Enter the monsters you actually own. Count separate copies of the same species individually.
Update your recorded inventory yourself after breeding. Planning does not change the quantities you entered.
Check a pairChoose two parents → see possible results526 monsters · 714 Wege
Choose both parents from all 526 entries. They are sorted by name. Both parents must have reached level 10.
The same species in both fields means two separate monsters. Retain a parent species continues a species you already own; it is not a new acquisition route. For Fuzzy, only results of that species are possible.

Add ancestry for four-grandparent recipes 19 documented routes
Enter these only if they are the actual ancestors of your two parents: pair A produces parent A, and pair B produces parent B. Fill all four fields. Each pair must be able to produce its stated intermediate parent.
The pair will be checked after loading.

Enter your inventory above. The tree will then show available and missing monsters.
Suggestion based on documented breeding routes. Both parents need level 10; check sizes, talents and your game edition yourself. For four-grandparent recipes, grandparents are planned again because inventory does not store ancestry. The shortest route is not guaranteed.
Your target is at the top, with its parents below. Expand only the earlier stages you still need.
Both parents must be at least level 10. Synthesis replaces them with the new monster.

Circle of Indulgence · Lower Echelon
Hotcake Heap: cross the honey and waffle bridges
The route to the top uses raised waffles. The lower bridge on 2F does not reach the destination.
Accept the request in Honeyton before entering the caves.Step-by-step solution
1F: Cross the honey stream on your right using the two waffle bridges.
Take the ladder at the end to 2F.
2F: Walk to the opposite side of the room and climb the narrow waffle ramp on the left.
Take the ladder and immediately cross the large waffle bridge on the right. Skip the lower bridge straight ahead.
Continue upwards over the colourful macaron steps.
The final ladder reaches the boss on 3F. Activate the teleporter before fighting.
Afterwards: The climb reaches the regional boss and the return teleporter.
Treasure tip: 2F: A pot in the small western side cave contains a Mini Medal.
Roofs, scaffolding and a dry canal bypass the blocked main street. This route covers the approach, not an interior puzzle.
Unlock the Middle Echelon of this circle.Step-by-step solution
From the area entrance, go slightly right around the metal shed and fence. At the end of the passage, take the ramp to the upper floor of the building.
Follow the scaffolding inside to the opposite exit. Cross the roof to the next entrance and climb the ladder.
Cross the roof bridge, go around the metal building and drop through the hole behind it.
Climb down from the pipes and leave the warehouse at the far end.
Go around the opposite building to the scrapyard. Follow the left-hand fence to its opening.
Drop into the dry canal and follow it to the other end.
Climb the ladder on the right, pass under the square arch, turn right and continue to the fort entrance.
Inside the fort, ordinary doors are unlocked. Walk through and look for the stairs to the upper floors.
Afterwards: Reach Fort Nox without opening every gate individually.
Treasure tip: 1F: Eastern pot. 3F: Pot in the passage. Each contains one Mini Medal.
Dragonspate: connect the rotating bridges up to 7F
The dragon switches rotate the central pillar and its bridges. If you have already used a switch, align the bridges to the stated directions instead of repeating the counts blindly.
Unlock the Upper Echelon and reach Dragonspate.Step-by-step solution · Spoiler
1F: Use the switch and go to 2F.
2F: Cross the bridge and use the switch once. Climb through 3F directly to 4F.
4F: Cross the western bridge, use the switch once and go to 5F.
5F: Descend to 4F on the opposite side. Cross the bridge there and continue down to 3F.
3F: Take the western bridge to 4F. Follow the outer ramps back to 5F.
5F: Use the switch twice, then cross the bridge to 6F.
6F: Use the switch five times until the bridge leads to the southeastern switch. Use that switch twice, take the southwestern connection and go to 7F.
7F: Use the switch twice and cross east. Use the switch there twice, then cross the new bridge to the boss area.
Afterwards: Access to the upper sanctuary and its boss battles.
Treasure tip: 6F: A pot contains a Mini Medal. Connect the side routes with the rotating pillar, then realign it towards the southeast.
🥚 Numbers = possible egg spots▣ F = treasure locationN ↑ North is up
Our simplified orientation sketches face north. Numbered points were approximately transferred from published location maps. They show possible egg spots, not guaranteed eggs or complete walking routes. Check seasons, bridges and elevation in the game.
Item names follow the linked English sources. Location descriptions explain where to search; treasure coverage is a selection, not a complete catalogue.
Finding eggs: colours, unlocking and repeat searches
White · Rank G / FSilver · Rank E / DGold · Rank C / BRainbow · Rank A
When do eggs appear?
Eggs unlock after taking over the Diabolic Hall. In the field they initially look white; their real colour is revealed when you open them.
The maps show possible positions. Actual eggs are randomly placed when you enter an area, with at most six present at once. No marker guarantees an egg or a particular monster.
Collect all eggs, fight one battle in the area, travel to another area and return. The current location guide gives an exception for the forest in Terrestria: 20 battles.
Switch update 1.0.6 added egg positions to the map. Use the display in your current game version alongside these orientation sketches. Older guides mentioning three eggs or ten battles describe earlier versions.
Rainbow eggs become available after completing the Middle Echelon of the Cradle of Corruption and contain rank-A monsters. Certain monsters are available only from eggs; the circle can affect their probability.
This selection covers seasonal field locations, equipment, scrolls and specific Mini Medal chests. Not every location is a chest. Source links open the relevant route; this is not a complete catalogue of every treasure.
This edition displays the English names recorded in the source database. Existing German names remain searchable aliases. No unverified monster translations are invented.
Our location maps follow documented possible spawn points. Their outlines are simplified and are not extracted from the game. Eggs appear randomly; not every marked spot has an egg at the same time. The treasure list is a selection of documented finds.
Monster images are original game material belonging to the respective rights holders. The database licence does not grant a separate image licence. Official game page ↗
