Artillery calculations

The blog post at gives a formula for calculating siege weapon damage based on projectile weight and velocity. Part of that formula involves the area of effect of the projectile. However, I don’t see anywhere where the calculation of area of effect is provided. Is there a rule of thumb for figuring the area of effect for an artillery engine?

The Dark, you... uh... You're really into this "replacing all your posts with a full stop" thing, aren't you. I'm kinda curious why. It marks every thread you edit as having new content, which kinda breaks that feature for other forum users.

There was no malicious intent behind this. We're working on a fix.
