So I went back and reread Szeth’s battle scene and realized in all the chaos I actually missed some huge Nightblood moments. Two things stood out to me:
Nightblood learning to grant Surges (or at least redirect Investiture into them)
Nightblood choosing to shut herself off — a major break from her usual nature
I want to unpack these, share a few thoughts, and see what everyone here thinks.
1. Surges — Nightblood as a “universal adapter”?
It didn’t surprise me that Nightblood was Connected enough to give Szeth power — he’s already used Nightblood, so there’s a pathway for it. But the crazy part is that Nightblood didn’t just burn the Investiture she consumed; she redirected it to a specific end. That’s new.
Some questions I’ve been thinking about:
Can Nightblood grant all Surges?
She says she’s “learned from the other swords” (plural). That almost certainly means Shardblades / Honorblades. Later she adds: “I can restore your Lashings; those are easy.” That wording makes me think she can recharge powers someone already had — basically restoring or fueling an existing spiritweb — rather than handing out totally new powers at will, but it seems at least possible that she could maybe grant surges or other magics to someone who has never had them.
Could Nightblood grant other magics (like Allomancy)?
If Nightblood spent time around Mistborn and got Connection to someone like Kelsier, could she “restore” his ability to burn metals? My guess: maybe . Surgebinding and Allomancy are patterned differently on the Spiritual level. Nightblood doesn’t seem to rewrite the spirit web, though its hard to tell with only one example, but for someone like Kel whos already got Mistborn wrighten in is sDNA it seems at least possible.
So what’s really happening?
I think Nightblood now can act like a kind of universal Investiture adapter. She burns what she consumes, but instead of annihilating it she can re-channel it through an existing Invested framework. For Szeth, that means fueling Lashings. For others… maybe more or less limited, depending on what their Spiritweb already supports.
It’s still insanely powerful, but maybe not “Nightblood can hand out every magic system to anyone.” Yet.
2. Reawakening — Nightblood choosing to stop
The other wild moment is when Nightblood just… stops. She doesn’t destroy Szeth or Kaladin, even though that’s her usual mode.
That’s never happened before. Even though Nightblood is sentient, she’s always been bound to her original Command: “Destroy Evil.” She never had the flexibility to just not. But now she does — at least in this one scene.
Why?
Odium overfill. Right before this, Nightblood maxed out on Odium’s raw Investiture — one of the most potent “feeds” she’s ever had. My theory: being stuffed with that much power stretched her Spiritweb / Cognitive Identity enough to create new degrees of freedom.
Learning from other swords. She specifically says she learned from “the other swords.” Maybe not just about Surges, but about how things work in the Cosmere — she’s picking up new Cognitive patterns from Shardblades, Honorblades, and even living sprenblades.
So I think we’re watching Nightblood evolve. She’s becoming more self-aware, more flexible, and less locked into her destructive function.
3. Big Picture — What This Could Mean
If Nightblood can now redirect Investiture and fuel powers instead of only consuming… she’s no longer just a doomsday weapon. She’s a potential tool — or worse, a wild card — for manipulating Investiture itself. That’s terrifying and exciting in equal measure.
open questions:
Can she eventually grant new Surges or powers, not just restore old ones?
Will the Odium infusion have lasting effects beyond what we’ve seen?
Could Nightblood ever cross systems and fuel something like Allomancy, Awakening, or Sand Mastery?
Or is this just the first step in Nightblood becoming something fundamentally new?
Lemme know what y'all think!
