Mold Recruitment in Goddess of Victory: Nikke allows players to recruit units using a currency called "molds."
There are several types of molds, including High-Quality, Mid-Quality, and Manufacturer molds, each with its own unique pool of recruitable units.
To recruit one unit from a specific pool, players need to spend 50 molds.

You can earn molds through various methods, including rewards from daily and weekly missions, event challenges, completing Tribe Tower levels, and purchasing monthly mission passes.

High-Quality and Mid-Quality molds include all SSRs from the standard SSR pool (excluding Pilgrims).
Manufacturer molds contain units from their respective pools; for example, Elysion molds feature Elysion units, while Pilgrim molds include Pilgrim units.

No, molds do not expire. You can use them immediately once you have enough for a roll, or you can save them until your favorite unit becomes available in the pools.

Units are added to their respective mold pools after their Pick Up banners end.

It depends on your goals and the units you're after.
New players might want to use molds right away to build their collection and break through the level 160 wall, allowing them to level up more units via the Synchro Device.
Veteran players might prefer saving molds for when new units they missed are added to the mold pools.

No, unlike banner recruitment, you don’t receive pity currency like gold or silver mileage tickets from mold recruitments.
However, you do earn body labels, which can be used to purchase additional High-Quality molds from the shop.

No, Abnormal units cannot be obtained through molds. They are only available via banner recruitment and specific events.

The mold system is RNG-based, so it's largely luck. Keep using molds, and your chances of getting SSRs will eventually come through.
