Difference between revisions of "Nightblood"

Nightblood is sentient but lacks a human context for its intelligence (sapience). Time has no meaning for it, nor can it well understand the dynamic aspect of human personalities. It can speak into Vasher's mind as well as Vivenna's, and it reads their surface thoughts whether they want it to or not. Though he thinks otherwise, Nightblood doesn't need to sleep.{{17s ref|post|66703}} Nightblood can more easily influence and is better able to communicate with people who are mentally unhinged.{{annotation ref|wb|chapter=53}}

When its clasp is undone and even a bit of its blade shows, it leaks an inky smoke. The smoke is the Breaths that it has absorbed from its victims, twisted and fouled, leaking back out.{{annotation ref|wb|chapter=51}} Those it defines as "evil" feel drawn to possess it; once an "evil" person picks Nightblood up, the sword amplifies the wielder's bloodlust causing him or her to slaughter anyone nearby and then commit suicide with the blade. Even while still in its scabbard Nightblood is very powerful and enhances the person holding him, once Nightblood is unclasped every part of it is a deadly weapon that--literally--yearns to kill evil-doers, Itit can smash bones and even run a menman through. Nightblood in effect Wields"wields" the person holding the sword and always kills its holder by driving its selfitself through their chest.

Once drawn, Nightblood becomes incredibly powerful. Its voice becomes overpowering. Lifeless that it touches disappear in a puff of smoke and stone also disappears when struck. It is unknown what happens to a Living creature that is struck by Nightblood. So long as Nightblood is unsheathed, it drains the Breath from its wielder, drawing Breath faster the longer it is held until it is all gone. If held until all available [[Investiture]] (i.e. Breath) is consumed Nightblood will feed on the spark of life, killing the wielder.{{qa ref|1086|16}} This will also happen to non-Returned that wield Nightblood.{{qa ref|979|69}} Nightblood can also feed on other forms of investiture, such as Stormlight{{qa ref|1100|2|Now that Nightblood is on Roshar, can it feed off of Stormlight the same way it can off of Breaths?|date=Jan 8th, 2015}}, although we have seen no evidence of this in text as of yet.
