Ambrose's window wards

Ambrose's window wards first emerge in The Wise Man's Fear as a cunning sygaldric defense, etched into thin brass strips along windowsills to thwart Kvothe's vengeful schemes amid their escalating rivalry at the University. These sequential runes detect intrusions, alert Ambrose through a linked item, and magically seal the window, showcasing Ambrose's growing prowess in artificing. Though only prominently featured in the second book, they underscore the series' theme of sympathetic magic weaponized in petty academic feuds, with no further evolution detailed in later volumes.
