Given how they specifically told Tayzilla not to use her breath due to the possibility of irradiating the surrounding area, they must be kind of stupid to allow a fight that might have a possibility of causing "a containment breach". An interesting consideration is what it would look like to observers. Would it cause Sophia's shadow state look like a cloud chamber with cosmic rays going through it, blue sparks or glow in the shadow state that looks like (and might be a form of) Cherenkov radiation, etc? The follow up investigation on why the fight was allowed might be interesting given that this occurred after the power testing.
Some scene I'm not taking the care to write out completely and is probably like half-canon:
Director Piggot: "So Triumph has sent me a note that Dragalier plans to have a spar with Umbra Huntress. I remind you that Umbra Huntress can shoot through solid objects and Dragalier is nuclear. Give me one good reason why I shouldn't shut this down now?"
Armsmaster: "According to previous tests of Umbra Huntress' powers, the metrics of Breaker effects when applied on other objects is much weaker. Her Shadowed Objects have a lower threshold when struck by energy -- like electricity or radioactivity, are more quicker to reform to normal and suffer much more rebound damage. For example, if she were to throw a shadowed-coin into an active lightbulb, the coin wouldn't phase into the bulb but instead reform within a fraction of second, bounce off from the collision, and experience internal destabilization. We calculate the risk of Umbra Huntress inflicting any damage to Dragalier to be negligible to nonexistent -- surface level, in other words."
Director Piggot: "So a great amount of electricity -- or radioactivity -- serves as a reflector-shield against Umbra Huntress' powers?"
Armsmaster: "High-percentage certainty."
Director Piggot: "Alright, now what about the opposite, how hurt would Umbra Huntress be if she tries to shadow through Dragalier?"
Armsmaster: "According to Umbra Huntress' own words and the one sample test we could perform... very hurt."
Director Piggot: "And for what reason should I allow a Probationary Ward to risk accidental death?"
Armsmaster: "Theory: If Umbra Huntress experiences a high enough energy level as to be fatal, then similar to the reactions of her Shadow Objects, she will bounce off instead of ghosting through. So she will most likely be a near-death state rather than be actually dead."
Director Piggot: (💥🔫) "Anybody else?"
Assault: "So they've got beef with each other, right? Might as well let them have this. Otherwise, they might
spar where we can't see them."
Director Piggot: 😠
Miss Militia: "Is Umbra Huntress' helmet not designed to detect energies that are dangerous to her?"
Armshot: "In a city, that would primarily be electricity and fire -- not nuclear. We should adjust it to detect all energies beyond a certain threshold that are harmful to her."
Assault: "We can let Hunt just try to shadow through one of Draga's limb? It's gonna hurt like a bitch. But even Hunt won't be stupid enough to try again after that, right?"
Director Piggot: "Are you saying I should allow a Ward to intentionally hurt herself?"
Assault: "Well, pain's the best teacher, wouldn't you say so, Big Boss?"
Big Boss Piggot: (💥🔫) "I hate that I agree with you."
Assaulted: "By the way, how does that work?"
Battery: "How does
what work?"
Assaulted: "Turning into a shadow but being weak to electricity. Like, her helmet is one fancy gizmo, ain't it? Wouldn't she just shock herself instantly?"
Velocity: "Breaker Powers include our clothes, of course. Otherwise we'd be naked every time we used our powers. Besides, the human body does naturally generate its own small electrical currents, among other energies. So her powers is just weak to
outside energies, I suppose."
Challenger: "I mean, in canon, Shadow Stalker carried around cellphone and communicators, right?"
Director Piggot: (💥🔫) "How dare you speak about canon."
Armsmaster: "Hey, Umbra Huntress. I heard about your upcoming spar.
Do not use your powers to move through Dragalier. Also, as a reminder, you
are restricted from using shadow-bolts and shooting people with it."
Umbra Huntress: "Yeah, whatever."
Armsmaster: "After your spar, go also visit the medical office. They
will be expecting you (and by that I mean Panacea who I have booked for this morning)."
Umbra Huntress: "Yeah, whatev-- No, actually, why? Think I'm going to get hurt or some shit?"
Armsmaster: "(🚨☢☢☢🚨) ...For no particular reason. That's an order."
Umbra Huntress: "Yeah, whatever, sir."
Armsmaster: "I repeat, don't do these things."
Umbra Huntress: "Later, Tin Man."
Armsmaster: 😐
📱Phonemaster: "Dragalier, this is Armsmaster. For your spar today, only target Umbra Huntress' limbs, do not ever aim or hit her torso or head. Keep her at arm's distance, so that if she does try to shadow through you, then she'll only move past your own limbs."
📱Tayzilla: "Uh, hey, good morning to you, Armsmaster. That's oddly specific."
📱Phonemaster: "...There may be
undesirable power interactions between you and her. Deadly for Umbra Huntress. Very deadly."
📱Tayzilla: "I'll, uh, keep that in mind."
