When does a special (non-green) die leave your die pool?

Question

I just started playing Elder Sign, and the wording in the rule book made me think maybe there was some way to keep using the yellow/red die beyond the current turn, if it was unused. Is this the case?

Answer 1

The updated rules state:

Unless dice are locked or secured by a spell, the player returns any dice granted by common or unique items to the supply at the end of the Resolution phase.
