Blood Droplet

You prick your finger, drawing a single drop of blood that you can shape and control for the duration of the casting. The droplet can perform one of the following effects:

     Analyze: You learn if a visible creature is living, undead, or a construct, and whether it is above or below half its hit point maximum.

     Mark: You place your blood droplet on a surface or object, creating a tiny mark visible only to you. The mark lasts for 24 hours.

     Message: You send a brief telepathic message to a creature whose blood you have touched within the last 24 hours. The message can be no more than six words long.

     Seal: You use your blood to seal a tiny crack or hole in an object. The seal is as strong as the original material but appears as a thin red line
