(b) Summons and notice. If the complaint is not served with the summons, the summons shall contain or have attached thereto a notice stating the nature of the action and the relief sought, and, except in an action for medical malpractice, the sum of money for which judgment may be taken in case of default.
(c) Amendment. At any time, in its discretion and upon such terms as it deems just, the court may allow any summons or proof of service of a summons to be amended, if a substantial right of a party against whom the summons issued is not prejudiced.
