Volume of a Colossal Animated Object?

[magicalmagicman]

I want to create a colossal animated object using wall of stone. We have an artifact that permanently animates an object as long as its attached. I want to calculate how long it will take.

1. I know colossal creatures take up 30ft by 30ft square, but what about height? 30ft? 20ft acceptable? 60ft? 5ft?
2. How hollow can the animated object be?
3. What is the volume of a colossal humanoid statue?

I am intending on making the statue look like a suit of armor. Fabricate spell is not available to us at the moment which is why I'm trying this out. Depending on the result I may have to settle with Gargantuan, hopefully not huge.

According to the SRD (http://www.d20srd.org/srd/combat/movementPositionAndDistance.htm) a typical biped Colosal creature is at least 64 ft tall and weighs at least 125 tons. Using this website (http://www.thecalculatorsite.com/conversions/weighttovolume.php) the volume of a creature made completely out of stone would be approximately 1750 cubic feet of stone. This is using metric tons, but the error is about or less than 10% when using short tons or long tons. Note that this is the bare minimum of Colosal size, but also the maximum of Gargantuan. The size can be increased to nearly 100 ft, and the weight would increase as well. Increasing the size to 100 ft (about 50% increase) increases the weight to (1.5^3 = 3.375) = 421 tons, or almost 6000 cubic ft.

Wall of Stone (http://www.d20srd.org/srd/spells/wallOfStone.htm) creates a 5x5 ft by 1 inch/4 caster level wall PER caster level. Assuming a 20 level caster, one casting of WoS creates 20 5x5 ft squares, each 5 inches thick. So a total of 20x(60x60x5) = 360000 cubic inches, or 208.3 cubic feet of stone. You will need abou 9 castings for a 64 ft tall one, and 30 castings for the 100ft tall one. Again to emphasize, this is a creature made completely out of stone, so you can easily half the volume and still have a reasonably sturdy statue left.

Hope this helps a bit

Thank you very much!

So 125 tons of Granite will result in 3,032,990 cubic inches
At level 11 wall of stone will create 60 x 60 x 2 x 11 = 79200 cubic inches of granite
3,032,990 / 79200 = 39 castings

Since level 11 sorcerers can cast this spell 4 times a day, it will take 10 days to make. Thanks!

If the statue was a rectangular prism thats 64ft high, 3,032,990 / (64 * 12 ) = 3950
srt(3950) = 63inches which is approximately only 5ft. So... this colossal creature when standing normally would only take up a 5ft square while being 64ft high...

Actually roughly measuring myself, my two feet is only 10% of my height, so i guess at most it would take 50% more castings to make the statue reasonably proportioned. Or I could make it hollow.

Alright thanks! 10-15 days is acceptable!

If you can manage to get 1 more Sorcerer (or equivalent) level somewhere, the bolded part changes to 60 x 60 x 3 x 12 = 129600. 3,032,990/129600 = 24 castings. A 12th level sorcerer can cast it 5 times per day, so it's only 5 days of work. That's only half of the time!

Also don't forget bonus spells from a high Charisma. If he has >20 Charisma (you are a terrible sorcerer if you don't have this at this level :smalltongue: ) he can cast it once more per day, reducing it to 8 days instead of 10. If he can increase his sorcerer level by one like in my example, it will take him 4 days (6 castings per day, 24 required)

Being level 11 or level 12 is a pretty big thing in this case :smallbiggrin:

(Small thing, granite (at least according to the website I linked) is a little bit more dense then regular stone, so the math is a little off, like 7 percent but whatever, you get the idea)

Oh yeah that was my editing mistake. I originally calculated for granite, but then it turns out STONE exists, so i went with that but forgot to edit that part XD.
