D&D (2024) Web: Power Overwhelming

[Rabulias]

Isn't 20 feet cube = 16 x 5 feet cubes in 2D and/or 64 x 5 feet cubes in 3D? (4 x 4 x 4 for 20 feet on each side and as much high)

D'oh! Yes, you are correct! Not sure where my brainfart came from there...

This is one of those interpretation errors that are a cliche in D&D.

Any scenario in which a multi-square effect appears to have cumulative damage per square is all but guaranteed to be in error. That is not how D&D design has worked these last decades, it won't suddenly be true for one niche scenario without being called out explicitly because it would be so unique.

The thing is, it would be so easy to write the spell in a manner that makes it very clear that you're not supposed to take damage per burning cube. In fact, it's so easy they already did it before!

From the 3.5 SRD:

"The strands of a web spell are flammable. A magic flaming sword can slash them away as easily as a hand brushes away cobwebs. Any fire can set the webs alight and burn away 5 square feet in 1 round. All creatures within flaming webs take 2d4 points of fire damage from the flames."

But the new wording makes clear that you can start a fire just by exposing any cube to flame. Whereas the 3.5 wording requires that to be extrapolated as an implication of what is said.
