Well.
We’ve been paving trolls since FR0001, and JK doesn’t even have them.
Besides...our Dark Forces are usually lab experiments that have gone :shriek!: horribly wrong, which we then set to rights with various combinations of electronics, dynamics, engineering and bravado. (Have I left anything out?)
There was a troll in Sorcerer's Stone - the big ugly thing in the bathroom, remember?
And you left out wine, pretzels, chocolate, and wishful thinking. I get a lot done with those.
