Midnight Bandana: This dark bit of cloth often commemorates tasks involving eliminating a threat to the community by stealth or sabotage. A halfling who wears it while casting sanctuary on herself can cause the spell to affect only one creature instead of all opponents within range. This creature gets a saving throw as normal to resist the effects of the spell. If it fails this saving throw, the halfling can attack it without automatically ending the spell. Each round in which the Halfling makes an attack against the target, regardless of the number of attacks or whether or not any actually succeed, the target may make another saving throw in order to overcome the spell and retaliate. Whenever the halfling successfully strikes the target, she reduces the remaining duration of the spell by 1 round. For instance, if the spell had 5 rounds remaining and the halfling struck the target three times in a single round, the spell has only 2 rounds left on its duration.
