Types of Synthesis and Methods
Systematic Fusion
Systematic Synthesis is a straightforward method involving the fusion of compatible monster types, categorized as A and B strains. When the Family and Rank of the parent monsters are identical, the synthesis outcome remains consistent, regardless of the specific monsters used within those categories. This method simplifies synthesis, eliminating the need to select specific monster pairings. However, it’s important to note that Systematic Synthesis cannot be used to increase the rank of the resulting monster.
Examples of Same Rank Combinations
| Parent A |
Parent B |
Monster Offspring |
| E Rank |
× |
E Rank |
Combining an E-rank monster from the Slime Family with an E-Rank monster from the Dragon Family will consistently yield the same E-rank offspring candidates: Drake Slime and Raptile.
Examples of Different Rank Combinations
| Parent A |
Parent B |
Monster Offspring |
| E Rank |
× |
C Rank |
When you synthesize an E-Rank monster from the Slime Family with a C-Rank monster from the Dragon family, the possible offspring expand to include E-rank monsters like Drake Slime and Raptile, as well as C-Rank monsters such as Noble Gasbagon and Shadow Slime.
Rank Limitations with A-Rank and Higher Monsters
| Parent A |
Parent B |
Monster Offspring |
| A Rank |
× |
A Rank |
The highest achievable monster rank through standard Monster Synthesis is B-Rank. Even when using A-Rank parents, the synthesis will not produce an offspring of A-rank or higher.
Species Fusion
Species Fusion, also known as Specific Synthesis, is a method that requires particular monster combinations, often involving monsters within the same Family. Monsters highlighted with a gold frame in the synthesis menu typically indicate a Species Fusion.

The Family of the synthesized monster is determined by both parent monsters. There are no complex combination patterns beyond the two parent system.

Certain monsters can be synthesized through two distinct methods: Family combinations and Rank combinations. While the base stats remain consistent regardless of the method, Family combinations often provide an advantage in producing higher-ranked monsters more readily.

A family strain combination involves pairing a specific monster family with another monster, irrespective of the second monster’s family strain or rank (G to S rank). This approach is more flexible than systematic synthesis, offering looser conditions for creating specific monsters.
4-Parent Combination
4-Parent synthesis is a unique and advanced method that requires specific grandparent monsters, rather than parent monsters. The exact parent monsters used are irrelevant, as long as the four grandparent monsters are the correct, predetermined monsters. These combinations often result in rare and exceptionally powerful monsters, typically requiring significant time and preparation to achieve.
4-Parent Combination Examples
| Granparents |
Parents |
4-Parent Monster Offspring |
| Magmalice |

Anything |
| Firn Fiend |
| Coralossus |

| Stone Golem |
Once the four specified grandparent monsters are obtained, the resulting 4-Parent Monster offspring will be consistent, regardless of the specific parent combinations used to reach this stage.
