Message: <blockquote data-quote="EarthSeraphEdna" data-source="post: 3793605" data-attributes="member: 49309">Well, the bestiary itself states: So yes, unless U_K has changed the rules regarding size category dimensions, a spherical creature with a 6-foot-diameter would be Large size, a 12-foot-diameter sphere would be Huge size, etc. However, I don't exactly agree with this due to the rule conflicting with the approximate weight for size categories.Using the formula for the volume of a sphere, [(4/3) * pi * r^3], we get a volume of 905 cubic feet for a 12-foot-diameter sphere (12 feet is the average prime dimension of a creature of Large size). The Bestiary states that 1.2 grams per cubic centimeter is the standard density of a creature with average strength for its size, which converts to about 75 pounds per cubic foot. Thus, a 12-foot-diameter sphere made of organic flesh and bone would weight 67,865 pounds or 34 tons. This is within the weight range of a Gargantuan creature. Thus, a 12-foot-diameter sphere would normally be considered Gargantuan instead of large, a +2 size increase.Let's try that again with a 96-foot-diameter sphere (96 feet is the average prime dimension of a creature of Colossal size). Using the volume for the formula of a sphere, we get a volume of 463,433 cubic feet. Multiply that by 75 pounds per cubic foot to account for flesh and bone composition and we get a mass of 34,757,475 pounds or 17,378 tons, which is within the range of a Macro-Fine creature.The same goes for cubical creatures. A 12-foot cube of flesh and bone would have a volume of 1728 cubic feet and a mass of 129,600 pounds or 65 tons, just within the range of a Gargantuan creature. A 96-foot cube of flesh and bone would have a volume of 884,736 cubic feet and a mass of 66,335,200 pounds or 33,178 tons, within the range of a Macro-Fine creature.From this we can see that a spherical or cubical creature is two size categories above a regularly-proportioned creature. However, should they be two size categories larger in all respects, or should they be given +2 VSCs instead? In other words, would a 96-foot-diameter sphere of flesh and bone be considered a Macro-Fine creature or a Colossal creature with +2 VSCs? Furthermore, (as was asked in my previous question), what would be the slam (parallel to the ground) and crush (against the ground) damage of this 96-foot-diameter sphere, and would the damage values change if it were a 96-foot cube instead (assume the cube is ramming using its corners or flat sides, whichever you deem to be more damaging)?</blockquote>
