+/// <summary>
+/// If it is the opposite gender of the user, the target becomes infatuated and less likely to attack. 
+/// </summary>
+/// <remarks>
+/// The target becomes infatuated with the user if they have opposite genders. Attract works regardless of type immunity.
+/// Unlike most status moves, Attract is able to bypass a substitute.
+/// Attract has no effect if the user and target have the same gender, or if either of them is a gender-unknown Pokémon
+/// (such as Magnemite). It also fails when used on a Pokémon that is already infatuated.
+/// Pokémon with the Ability Oblivious or under the protection of Aroma Veil are immune to the effects of Attract. If
+/// a Pokémon is infatuated by Attract while holding a Mental Herb or an Eggant Berry, the item will be consumed and the
+/// infatuation will end. Even if the Pokémon has Oblivious, the item will still be consumed.
+/// If the target Pokémon becomes infatuated while holding a Destiny Knot, the user will also become infatuated with the
+/// target.
