I'm concerned that the Strength may too low.

The Gargantuan template is for a creature roughly 8 times larger (longer) than the original, but a Gammaroid is up to 125 times larger than an average-sized Giant Snapping Turtle going by the shell diameters (2,500 feet vs. 20 feet).

Consider it in terms of

**Carrying Capacity** vs. body weight.

A Giant Snapping Turtle weighs 15+ tons and has a heavy load of 12,480 pounds (Str 32 = 2040 lbs carry, Huge quadruped = ×6 load), a load-to-bodyweight ratio of 0.416.

The Working Draft Gammaroid has a heavy load of 1,413,120 pounds, (Str 36 = 58,880 lbs carry [Str 26's 920 lbs ×64 for +30 Str], Colossal quadruped = ×24).

That's 706 short tons, which seems pretty impressive - until you realize how massive a Gammaroid is.

So how much does a Gammaroid weigh? If it has the same proportions and density as the Snapping Turtle, it's a simple matter of scaling it up.

Let's see...

2,500 ft. Gammaroid shell divided by 20 ft. Turtle shell is a length ratio of 125. Cube that 125 gets a volume ratio of 1,953,125. Multiply that by the 15 ton weight of the Giant Snapping Turtle and we find the Gammaroid weighs...

*Almost thirty million tons!*
29,296,875 tons, to be precise.

That makes a 706 ton carrying capacity woefully low. It's a load-to-bodyweight ratio of 0.000024098, or a shade more than one part in forty thousand of the Gammaroid's bodyweight.

Now I'm going on the assumption that the 2,500 foot shell is for a particularly big Gammaroid. If our base Gammaroid is "only" 1,000 feet in shell diameter it'll still weigh around two million tons (the above sum works out to 1,875,000 tons).

For the sake of argument I'll be using that assumption for the working draft. A 1000 foot shell plus 2 million ton weight.

If it has the same load-to-bodyweight ratio as the Snapping Turtle, it'll need to be able to carry about 832,000 tons. For a Colossal quadruped to carry that much with its ×24 size multiplier it'll need a Strength of...

...about 107.

**[**A Str 107 Colossal quadruped has a carrying capacity of 1,635,778,560 pounds (817,899 tons)

**]**
That's too high for me - I don't want them to be stronger than a

**Draeden**! Although a Str around 70 or 80 like a

**Stone Colossus** or

**Iron Colossus** would be acceptable.

So, how about we give the Gammaroid an ability to lift exceptionally heavy loads, like we did the

**Ferry Turtle** while also increasing its Strength score?

e.g.:

Str:

74
**Carrying Capacity:** Due to their prodigious size and sturdy build, gammaroids can bear immensely heavy loads. Their carrying capacity is

a hundred times that of an ordinary creature with their size and Strength. A typical gammaroid can carry a light load of up to 286,720 tons, a medium load of 286,721-573,440 tons, a heavy load of 573,441-860,160 tons, and can drag 4,300,800 tons.
