The flavour text for the M:tG card Safehold Sentry suddenly comes to mind:
"These bracers were worn by my father and by his mother before him. Boggart fangs have shattered on them. Cinder flames have withered at their touch. While I wear them, the safehold will not fall."
EDIT: from the same block, Wilt-Leaf Cavaliers:
Every elf in Shadowmoor is charged from birth with a terrible duty: to strike back against the ugliness and darkness, even though they are all around and seemingly without end.
Obviously, these can't be used directly, but perhaps they can be modified?
