That’s what you get for not casting it on the “This is not a place of honour” sign near the jagged black obelisks after encountering the colony of glowing cats

i cast mending on the pile of lead, giving me a solid cubic foot of weapons grade plutonium.

That is a really good question... I feel like radiation should have some sort of translatable element as a generic radiant danger, but for the rest... if it doesn't make sense without context in the source language, does it make sense after 'comprehend language'? Kinda feels like we need a 'comprehend science' or something if they wanted to grasp the idea of specific elements and units of measure.

Hmm, I think as a DM I would roll an arcana check to see if the wizard would conceivably have heard of radiation from arcane studies. It's reasonable to assume people with arcane knowledge would be the first to hear about the strange metal chunks that everyone keeps dying around. One of them would have had to have come up with a word, if not some variation on "death cursed"

This forest of thorns looks really cool, I bet deeds are commemorated here

There's always a relevant xkcd.

"cancer-light"

Oh thank god! I guess this is the "find the right answer by posting the wrong answer."

Disease-light might be the best medieval equivalent, actually.

Isotopes only have a "worst by" date unfortunately

"Death-light", maybe? Depending on the intensity.

With 3,174 comics and counting - it’s becoming more and more probable! Just like how The Simpsons can be credited with predicting a whole bunch of things; volume is key!

But if it's a blue flash, that's a completely different effect and there was a criticality accident and you're probably going to die.

Researchers came up with a warning symbol for this exact scenario "In the aftermath of repeated incidents where the public was exposed to radiation from orphan sources, a common factor reappeared: individuals who encountered the source were unfamiliar with the trefoil radiation warning symbol, and were in some cases not familiar with the concept of radiation. During a study in the early 2000s, it was found that only 6% of those surveyed in India, Brazil and Kenya could correctly identify the meaning of the trefoil symbol." https://en.wikipedia.org/wiki/ISO_21482

hey DM what's the range of mending? as long as it's over a few kilometers i should be fine

Sickglow stones?

I'm not feeling creative today so I'll just write "Dildo joke".

It's only glowing blue because there are orcs nearby.
