Trust me, I can see it all in my magic orb

"Radiation-emitting" would be correct in this case. As it reads now, the ball is made of radiation and is itself emitting plutonium.

So, it's a sphere of radiant damage?

Ponder the orb

Nononono whyyyy is it emitting plutonium, the plutonium would be emitting radioactive particles D:

Also, it likely wouldn’t glow blue since there are no reflectors, so it wouldn’t reach criticality.

I love this one regardless :)

Reminds me of the Lia radiological accident. Maybe they too were wizards.
