The latest official breakdown for Magical Girl Yusya-chan and the Labyrinth of Lust introduces Equipment Synthesis, a gear-improvement system built around transferring enchantments. At furnaces found inside dungeons, players can move an enchantment from one piece of equipment onto the gear they are currently using.
Weapons use gems, while armor uses ribbons, and both equipment types come with randomly assigned enchantments. That makes finding gear only the first part of the process: Equipment Synthesis lets players fold desirable effects into an existing setup rather than relying entirely on a perfectly rolled item appearing.
There is another random variable to consider, too. Each piece of gear has a randomly determined enchantment capacity, so equipment capable of holding numerous effects is particularly valuable to build up. In practice, that positions high-capacity gear as a stronger foundation for customization, while gems and ribbons carrying useful enchantments become potential synthesis material.
Identical enchantments can also be stacked, although the announced rules include unspecified exceptions. The full limits have not been detailed, but stacking should make repeated copies of compatible effects relevant instead of automatically redundant. The key decision is therefore not simply whether a new gem or ribbon is immediately stronger, but whether its enchantment can improve the gear already in use.
Equipment Synthesis gives dungeon furnaces a clear role in that loop: find randomly enchanted equipment, identify pieces with room to grow, and transfer useful effects into a more focused build.
