Crystalline Memories

You can cast this spell on a creature with Intelligence score of 3 or higher. When target fails on a Wisdom saving throw, the spell works. You have to study on target for the consecutive 3 rounds and concentrate. If you lost your concentration during this, the spell ends.

After your study is finished, the surface thoughts of your target fills into a crystal shard. This shard comes out of your target and deals 2d10 Psychic damage and 2 Intelligence damage, and it comes to you by floating.

When you have the shard, you can use an Action to open it and see the memories. The shard disappears after you look inside or after 24 hours passed.
