Quest magnus are used to trap the magna essence of various items, storing them in a card. Kalas obtains four blank quest magnus very early in the game, and will get more as he progresses. Quest magnus are used for carrying items related to puzzles and sidequests. The contents of a quest magnus will sometimes change over time. For example, lava will eventually harden to a hot rock, which will eventually cool to become a pebble. Once the contents of a Quest Magnus have been exhausted, they can be refilled with any other appropriate contents.
