My dude you don't play enough games with looting mechanics if you haven't run into several variations of "this thing has no pockets, how is it carrying a bazooka?"

The last bit is just a deviation used narrativley at times to add in an extra joke layer. It tends to make up for the need to shoehorn it with the comedy of the statement. In this case, that ten random gems enhances someone's sword and alludes to the fact that, in a very narrow view, these mechanics turn players into little loot goblins searching for random crystals inside dead things to improve items.

OP did a mash-up of video games and real life to turn the absurd logic that results into a joke. You're just taking it too literally. And I say that as someone who often does the same.

Also the fact the dude is like "Here is a magic crystal" but is shocked at the mention of a sword is weird as well.

> the person being operated upon says "I need 10 of those to upgrade my sword."

That's not the person on the bed that says that, it is another doctor or nurse. The person on the bed has there head on the left side of the frame. Where the breathing tube is.
