Dye's Capture Conversation

As a reaction when a creature begins saying something you want to remember, you cast a spell that records sound from a point you choose within range. The receptor is invisible and hears like an ear, with similar advantages and limitations.

Until dispelled, all sound within normal hearing range is recorded. When the spell ends, a tiny crystal appears in your hand that contains the entirety of the sounds heard. This crystal can play back its contents at the normal volume that it was recorded, which you can activate or deactivate as an action. The crystal can be any shape or color you choose.

If you step more than 10 ft. away from the point you chose for the receptor, the spell ends.
