absolute ring question

They do get used up to make the Absolute ring. The notes say they are "combined".
As to what happens to them if you don't combine them, the extraction does have tradeable versions of them all, but the notes don't say anything about making them tradeable (in the past it took an extra day of waiting an hour with the potion for that).

I thought the + day was the day to make them tradable by holding a potion for an hour. But it doesn't make since to make them tradable if they are going to become a combined ring. Guess we'll find out. Poorly worded events are my favorite (sarcasm).
