Sirines preferred not to engage in direct combat. Rather, they tended to use their abilities to escape back to their home. Sirines could charm another creature and could damage their foes' intelligence. Some sirines used bows, slings or javelins as weapons and a small number carried magical javelins.
A single touch from a sirine had a chance of instantly reducing the target's intelligence. This effect lasted until dispelled with magic, or until any sirine touched the victim again.
They often frolicked with strangers, although only for a short amount of time and almost never invited strangers back to their lair.
