((Super sorry that took so long guys. Work has been kind of crazy, I didn't even really get a lunch break today.
If Viss wants to cast Transmute Metal to Wood on Aldebaran, I'm going to give him a saving throw to resist it because he's a living creature - and a boss, no less - so a no-save insta-kill seems kind of excessive, plus the spell wasn't designed for non-magical settings.
So yeah, she can try it and he will get a saving throw to resist it.
I'm going to assume that Viss does that in the interest of saving time, and..... ::rolls dice:
)
Aldebaran scoffs at Shulmor's attempts to intimidate him. "You treat me like a peasant at your own peril," he grumbles, unleashing a bone-shattering backhand at the Lich and sending him reeling, unable to keep from collapsing to the floor.
"Once.... I figure out..... your secrets...." he says, intermittently pausing to stomp a thick metal leg directly onto Shulmor's skull, "You.... Will decorate.... My mansion!"
The final stomp produces a large, ugly crack in the Lich's bone structure.
He turns slightly to address his Droids. "Enough of this! Execute Pattern Theta!"
The droids immediately stop what they're doing and rearrange themselves in a loose circle which encompasses the entire party, save for Viss. A large network of barely-visible fibers begins criss-crossing in a pattern, creating a paper-thin dome over everything.
The dome immediately crackles to life, and is filled with a paralyzing electric burst. Even Satra, in his partially intangible form, is swept up in its power. Fleshbane's circuits are temporarily overloaded and he can scarcely move.
"I grow tired of these games," Aldebaran speaks now. He seems unaffected by whatever energies have afflicted the party. "Soon you will all be unconscious, and then the real fun can begin."
He makes a demented cackle, which fills the room and the ears of the party....
...And then, abruptly, the cackle turns to panic and anguish.
Before everyone's eyes, the entire room begins to rapidly change form. Tables, the floor, the walls, the ceiling, instruments, tools - everything turns brown and inert. The dome of microfibers turns into a canopy, and the electrical attack ceases faster than it started.
The droids are swept up in the effects of the spell, powerless to prevent themselves from turning into wood. ALdebaran seems to be resisting somewhat.... but not nearly enough.
"No.... No! What is this?!" he shrieks. Gradually his body begins to change- starting at the bottom, keeping him rooted to the floor, and steadily creeping upwards. He bends down to knock on his unmoving legs. "WOOD?!" he blathers. He whirls around to Viss and glares at her. "YOU! Undo whatever you've done right now! I command you! I gutted your friend and I'll gut you too! I... I...."
A look of pure terror engulfs Aldebaran's face as the wood reaches his neck. He screams a blood-curdling (yet no doubt satisfying) howl of horror just before his mouth, and, ultimately, the rest of his head, is completely transformed.
((I won't require a saving throw from Fleshbane because he's both magical and a sentient creature.
I made the roll to overcome spell resistance of everyone's magical weapons and armor for Viss, and it was a 17 total, so no one's equipment gets transformed.
Combat is over))
