Secret Shop

The Secret Shop is a shop type available in The Alchemist Code that offers premium items and packs at associated prices. Items are offered in the Beginners' Shop, only available to new players, the Adventurer's Shop, which is updated periodically and always contains the same items, the Secret Shop, whose inventory depends mostly on which units are currently featured in banners, and a variety of event shops focused around limited-time campaigns (such as collaborations and holidays).

Beginners' Shop
This shop is only available to players for the first 7 days they play and contains a variety of useful items at a steep discount from the normal rates. It's recommended that all new players take full advantage of this shop and buy as much from it as possible while it's available to them. Definitely buy all the zeni items and it might be worth buying the equipment sets for gems to save on farming. The items for paid gems are all a good deal if you plan to spend money on the game except the Start Dash Set but will not be available to free players.
