Magical white darkness spreads from Charon's Claw in a 5-foot-radius sphere that only the wielder can see. The only other means of seeing through this form of darkness is through Truesight. 

White Darkness lasts for 10 minutes and will move with the sword during the duration. Being within this white darkness causes the user to appear invisible to prying eyes, thus gaining the effects of Greater Invisibility. The effects of White Darkness end if the wielder drops the sword or if the wielder is Incapacitated. White Darkness does not grant its wielder the abiltiy to see through other forms of magical Darkness.
