Monster synthesis is the most powerful tool at your disposal for creating stronger monsters and unlocking new species. It involves combining two monsters to create a new, often more powerful, offspring. The offspring inherits stats, skills, and sometimes even Talents from its parents. The key to successful synthesis lies in understanding the 'family' and 'rank' system, as well as the specific recipes required for certain monsters. You can access the synthesis menu from Rosehill or certain other locations.
When performing synthesis, pay attention to the 'plus' value of your monsters. Monsters with higher plus values (e.g., +1, +2) will produce offspring with better starting stats. Furthermore, the offspring's base stats are influenced by the parents' stats. Always try to synthesize with high-level parents to ensure a strong offspring. Don't be afraid to experiment; the Monsterpedia often provides hints for specific synthesis recipes. The ultimate goal of synthesis is to create high-rank monsters with optimized Talents and stat distributions, tailored to your combat needs. Remember that monsters revert to level 1 after synthesis, so you'll need to re-level them.
