Physical projectile damage technology improve artillery shells damage same value as canon shell. Original idea ArtilleryUpgrades.
Why
Mod like rampant or light artillery require a little boost of artillery damage. I always feel the designed goal of artillery was to one shot pretty much anything. Contrary to original mod I changed from stronger explosive to physical projectile damage, cause canon shell was more similar to artillery shell than missile that is only explosive damage. AFAIK, there is no way to split to damage boost for physical damage and explosive damage. Inform me if there is a way.
