Obtaining
[edit | edit source]Purchasing
[edit | edit source]The main method of obtaining Blue Crystals is purchasing them from the Store. [unfinished]
Rewards
[edit | edit source]A small amount of Blue Crystals can be recieved for free by completing Hunter Missions, Explorer Missions and Artisan Missions. Note that some of the missions are locked behind paid content, so not all of the Blue Crystal rewards are obtainable for free.
Uses
[edit | edit source]Blue Crystals can be used for a variety of things.
Purchasing Gold Coins
[edit | edit source]In the Store, the player can purchase 
Gold Coins in exchange for Blue Crystals. Just like purchasing Blue Crystals, when using an offer for the first time, the player gets a 20% bonus amount of coins. For example, when purchasing coins using the 100 000 coin option for the first time, the player will recieve 120 000. Each additional use of this option will give 100 000 coins. This does not affect other offers; after purchasing the 100 000 coin option, the player may purchase the 50 000 coin option and will still recieve an additional 10 000 coins as a bonus.
| Gold Coin | First Purchase Bonus (20% increase) |
Price (Blue Crystals) |
|---|---|---|
| 10 000 | +2 000 | 100 |
| 50 000 | +10 000 | 490 |
| 100 000 | +20 000 | 950 |
Replenishing insufficient resources
[edit | edit source]When the player lacks resources for repairing or upgrading a building, or trading near the Campfire, Blue Crystals or 
White Crystals can be used to purchase the missing resources. The price depends on the resource and the amount of the resource. The price in Blue Crystals is calculated by multiplying the total price of all missing items in Gold Coins by a factor of 0.1 and rounding up. The price in White Crystals is calculated by multiplying the total price of all missing items in Gold Coins by a factor of 0.5 and rounding up. Some example prices are listed below.

Unlocking slots
[edit | edit source]In some buildings, such as the Taro Field, the House and the Kitchen, additional slots can be unlocked using Blue Crystals. The price is 20 Blue Crystals for 1 additional slot.
Direct completion
[edit | edit source]Some time-based events, such as waiting for food to be ready in the Taro Field, the House, and the Kitchen buildings, or constructing weapons in the Workshop, can be skipped or shortened using Blue Crystals, ads, or 
Boost Vouchers. The price of direct completion depends on the time that the player needs to wait, and can be calculated using the formula: ceil(minutesLeft / 7).
