Put the constellation under the arrow in the first pull down menu. Then the other constellation with the moon phase as the other pull downs. Compare the numbers revealed with the Almanac for the offering items.

*I'm still looking for a replacement link that's spoiler free, I'll update when I find one.
In the meantime, the "spoiler wheel" below only skips the step of looking up the items in the almanac, you still need to enter the details correctly.


SPOILER WHEEL

https://codepen.io/johnwun/full/eLobpO

Just put in the details, and it will tell you the items you need.

This puzzle harkens back to the pre-internet days of game copy protection coming in the form of physical codes or puzzles that came in the game box or printed in the game manual. In this case it's in the form of a code wheel that you need to turn to the right constellations.

Each of the offering statues has an arrow, a moon phase, and two constellations, arranged like this:

In order to access the reward in each statue, you need to make note of the constellation under the arrow (or what I'm calling the "main constellation"), whether the moon is Waxing ) or Waning (, and what constellation is under the moon (what I'm calling the moon constellation).

Go to the "digital code wheel" here: https://www.inxile-entertainment.com/bt4-code-wheel

From the pull down menu next to "Constellation", enter in the "main constellation"
Then specify the Moon Phase as Waxing or Waning (the digital wheel has a helpful image in each menu item so you can easily reference which one you need)
and finally, the "moon constellation" goes in the final pull down menu next to the moon phase menu.

This will give you two numbers in the middle of the code wheel. These are the item codes.

Reference the item codes from the "Adventurer's Celestial Almanac" in game book, found at the top floor of the Adventurer's Guildhouse. Alternatively, you can use the table in this guide, if you'd like a searchable version.

Temporary alternate link: https://codepen.io/johnwun/full/eLobpO

Click the arrows next to the left constellation until it matches the "main constellation"
Click the arrows next to the middle constellation until it maches the "moon constellation"
Click the moon pulldown to specify whether the moon phase is waxing or waning
Click where it says click to get item names. Note this skips the step of looking up item codes in the almanac, but it's one of the only links I've found that doesn't require a download.

Insert these items into the offering statue and you should receive a reward.



For example, one of the first statues you find looks like this
`
Plugging that information into the digital wheel, it should end up looking like this

Referencing that against the almanac, 69 is Cabbage, and 78 is Keg.

Click "Make an Offering" on the statue, and Insert a cabbage and a keg in to the slots, and you should get your 300G!
