User blog:Mr. Bambu/D&D Homebrew Calc: Don't Touch Lamps

Premise
During a mid-tier adventure, Orric unleashed a Djinni. While we eventually took it down, that was not before it unfortunately nuked several desert villages.

Calc
Apparently, a village has about 1000 people.

Population density states that 14.7 people on average take up 1 km^2. This sounds really high, though.

Instead, we'll compare to Makkah (Mecca) in Saudi Arabia. Population is 1919900. Land area is 463 mi^2, or 1199.17 km^2.

1199.17 / 1919900 * 1000 = 0.625 km^2 area for our proposed area.

Plug this in here to get a radius of 0.446 km, or 446 meters. Assuming an explosion wiped it out...

R = Y^1/3 x 0.28

R = Radius in km

Y = Yield in kilotons of TNT

Plug in values to get 4.04 Kilotons of TNT, or Small Town level+. Makes sense for the time.
