The Dead Prince is Quite Rich

Abel decided to move onto Prince Adolf's necklace. It was a violet-gold piece with a blue gemstone in it. When he scanned it with his power of the Will, he could tell that it was an extraordinary magical item.

The person who made this was pretty thoughtful. By scanning it with his power of the Will, Abel could tell that a bunch of messages that were written on it, including the name of its creator, the instructions for how to use it, and some things to be cautious of when using it.

The name of this piece was the "ice dragon's protection necklace." Its ability was passive, which was both extremely rare and precious. No activation was needed to use it. It would switch itself up automatically once certain conditions had been reached. In other words, it could protect its wielder's life even when, say, he was asleep or something.
