MMMMMMM

Hear me out.

Warbreaker:

It's just such a great way for more of Nightblood's personality to be expressed: his self-assuredness; his demand for attention; his chipper eagerness to destroy evil, or, failing that, kill; and his command to destroy.

I don't know how the clasping&unclasping, drawing&sheathing will be done, or how to express the many times that Nightblood is sticking out of a man's chest. But the fight scenes with black smoke swirling is going to look sooooo cool. And there's just so many other awesome/funny things:

The whole thing of Vasher continuing to think of Nightblood as just a mindless object, while Nightblood insists on being treated as a person -- this works especially well! The 'I need fresh air and sunlight," the "I can tell. I've decided that I can" and the "a person knows when they’re in darkness, even when they  can’t see." Excellent.

Vasher checking if Nightblood's face makes people puke.

Vasher tossing Nightblood as distraction/bait at bad people turns into Nightblood smoothly sliding across the stage.

Nightblood posing as he is being admired/lusted after.

Walls/floors/other parts of the set that crumble and disappear when Nightblood touches it.

Nightblood chastising Vasher and Vivenna for being terrible at sneaking. Meanwhile, Nightblood is the only character dressed completely in black, on the very very bright, colorful stage.

Nightblood saying, "I'm better than a shirt. I'm a sword." But. It is a person.

Hear me out.

Warbreaker:

A musical motif/melody that is sung whenever someone Awakens/says "My life to yours, my breath become yours"

A dramatic duet between Siri and Vivenna where they're both singing basically the same thing about how "this wasn't what my life was supposed to be" when Siri gets shipped off to marry Susebron

A subsequent duet where Siri is marvelling at the colors of Hallandren and Vivenna is disgusted/terrified by them

Vivenna briefly singing Siri's part of the previously mentioned duet about the colors when she gets her breaths because she's overwhelmed by the wonder of it all

A song where Denth and Tonk Fah comedically lament about how much people assume about you when you're a mercenary

Everyone in the Court of Gods sings except for Lightsong, reflecting his disillusion with the whole system

Hoid's story as a song

Siri tries to start a duet with Susebron when she finally breaks the no talking rule out of frustration

A heartbroken reprise of the previous song when she realizes he can’t speak at all

A super over-the-top villainous reprise of Denth and Tonk Fah’s mercenary song when they reveal their betrayal to Vivenna

Vasher doesn’t really sing a lot (the exception being when he says “my life to yours, my breath become yours”), but Nightblood does

Nightblood, of course, sings a song about destroying evil

Denth sings the whole time he’s fighting Vasher/Vivenna, like the dramatic little bastard he is

Lightsong sings for the first time when he gives his breaths to Susebron

Susebron and Siri duet!!!

Vivenna singing in the epilogue 

Seth Everman totally has big Szeth energy. Like. Just look at him.
