(A) a defendant may offer evidence of the defendant's pertinent trait, and if the evidence is admitted, the prosecutor may offer evidence to rebut it;
(B) subject to the limitations in Rule 412, a defendant may offer evidence of an alleged victim's pertinent trait, and if the evidence is admitted, the prosecutor may:

(b) Crimes, Wrongs, or Other Acts.
(1) Prohibited Uses. Evidence of a crime, wrong, or other act is not admissible to prove a person's character in order to show that on a particular occasion the person acted in conformity with the character.
(2) Permitted Uses; Notice in a Criminal Case. This evidence may be admissible for another purpose, such as proving motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident. On request by a defendant in a criminal case, the prosecutor must:
(A) provide reasonable notice of the general nature of any such evidence that the prosecutor intends to offer at trial; and
(B) do so before trial, or during trial if the court excuses lack of pretrial notice on good cause shown.
(c) Evidence of Similar Crimes in Child-Molestation Cases.
(1) Permitted Uses. In a criminal case in which a defendant is accused of child molestation, the court may admit evidence that the defendant committed any other acts of child molestation to prove a propensity to commit the crime charged.
(2) Disclosure. If the prosecution intends to offer this evidence it shall provide reasonable notice in advance of trial, or during trial if the court excuses pretrial notice on good cause shown.
(3) For purposes of this rule "child molestation" means an act committed in relation to a child under the age of 14 which would, if committed in this state, be a sexual offense or an attempt to commit a sexual offense.
(4) Rule 404(c) does not limit the admissibility of evidence otherwise admissible under Rule 404(a), 404(b), or any other rule of evidence.
