A chill blade is a magic dagger that glows white. It grants its wielder the ability to activate it, upon which it can confer extra damage upon a target, and imposes a magical effect on the target such that the target's own attacks are reduced in effectiveness for around an hour. The blade does a reduced amount of extra damage against the undead, but has a probability of turning them, causing them to flee temporarily.
A chill blade is resistant to cold. It can be created from a regular ferrous metal dagger, a snowflake or ice, a chill touch spell, a lightning or electrical discharge, and a piece of rock crystal. As of 1368 DR, chill blades were worth around 1,000 gold pieces.
