Daenerys' dragons may be more effective against the undead wights, whereas the White Walkers themselves appear to be immune to fire. But they are vulnerable to dragonglass and Valyrian Steel. I hope that Bran's visions of the past could bring the Northerners the secret to manufacturing Valryrian Steel, with which they could arm their soldiers.
