When you cast this spell, you touch one willing creature an extract one thought or idea from their mind. You create a tangible silvery string that contains this thought or idea.

When you create a though strand, a target can choose to also forget the idea. If it choses to forget the idea, the thought strand lasts until dispelled. If the target choose to retain the memory, the strand has a duration of 8 hours.

Any creature that touches the thought strand can use an action to learn the thought or idea therein. If the strand has a duration that lasts until dispelled, using the strand to learn the idea within makes the strand disappear.

If you cast this spell while you are concentrating on a spell that interacts with a creature's thoughts (such as detect thoughts or modify memory), you can extract thoughts from that creature even if it is not willing. If this spell is used with any spell that merely divines the targets memories, the duration of the thought strand is 8 hours. If this spell is used with a spell that forces the target forget something, the duration of the thought strand is until dispelled and the thought strand you create contains the forgotten memory.
