GLOG Class: Stretch Thompson

A: Alter Size
B: Variable Specificity, Explosive Expansion

C: Gastronomic Scaling

D: Adjustable Density, Independent Dimensionality

Background: [1d3] 1 = giant-kin, 2 = witch's child, 3 = severe pituitary malfunction

Starting items: an exceedingly large lightweight robe,  (if regular nudity is embarrassing for your table, you also get a set of magic underwear that changes to fit you no matter what, but comes only in a drab color)

You gain +1 HP per template. 

(A) Alter Size

You can increase and decrease your own size; this takes about 5 seconds. None of your items or gear transform with you. Your HP doesn't change; any damage scales accordingly, so if you get a small cut while small, it'll become a big cut when you get big.

There's no equation that feels as good as these numbers, so:

Here is the table of the maximum and minimum sizes you can reach by height, per template:

• A: max of 8 ft., min of 3 ft.
• B: max of 12 ft., min of 1.5 ft.
• C: max of 20 ft., min of 6 inches
• D: max of 36 ft., min of 1 inch

You can increase or decrease to any given size within the maximum and minimum. 

When you transform, in addition to height, you change your weight accordingly. The equation to calculate weight is as follows: [current height / standard height]³ * standard weight. That's a scary-looking equation if you're like me, so here's some fast references, assuming you're 6 ft. tall and weigh 200 lbs.:

• 36 ft = 43,200 lbs. (a grey whale)
• 20 ft = 7,407.41 lbs. (a medium elephant)
• 12 ft = 1600 lbs. (a large polar bear)
• 8 ft = 474.07 lbs. (a big lion)
• 6 ft = 200 lbs. 
• 3 ft. = 25 lbs. (a beagle)
• 1.5 ft = 3.125 lbs. (a rabbit, ish)
• 0.5 ft. = 0.11 lbs. (a very long mouse)
• 1 inch = 0.0005 lbs. (about 10 grains of rice)

Roughly speaking. Most adventurers are not precisely 6 ft. tall and exactly 200 lbs., but this is a good chart for estimation.

When you transform, your Strength score increases or decreases accordingly, equal to +/- [templates * 2] per size shift: at 8 ft., you'd have +2 STR, at 12 ft. +4, and so on. At 3 ft. you'd have -2 STR, at 1.5 ft. -4 STR, and so on. There's no real basis for this, it's just what feels reasonable.

(B) Variable Specificity

You can alter the sizes of each of your body parts individually: you can increase your hands while decreasing your head, say. 

Internal organs match their closest exterior counterparts, and your circulatory system (heart, lungs, veins, etc.) can account for any such discrepancies as if you were one evenly-ratio-size person.

(B) Explosive Expansion

If you expand while inside of another creature (like, say, you crawled down their throat), that is smaller than the size to which you are currently growing, make an STR check. On a success, they rupture at the seams and suffer catastrophic damage. On a failure, they manage to force you out of themselves before reaching the critical point: they take no damage. 

(C) Gastronomic Scaling

Any objects wholly contained within your stomach transform in size with you, maintaining their exact relative dimensions. Their density doesn't change; just volume and mass.

This means, for example, that you could swallow a toothpick, grow to 20 ft. high, hork it back up again, and have an ordinary-sized baton.

(D) Adjustable Density

In addition to your general size, you can choose to either have your own weight fit according to your size, or you have it remain at 200. This rapidly changes your density: a regular 6 ft. 200 lbs. human, blended down, is about 2 cubic feet, giving you a density of roughly 100 lb/ft³ (extremely rough, I'm not a physicist).

For reference, here are some common densities:

• Water: 62.25 lb/ft³
• Air: 0.0765 lb/ft³
• Feather: 0.156 lb/ft³
• Iron: 491.5 lb/ft³
• Oak wood: 45.57 lb/ft³
• Granite: 103 lb/ft³
• Gold: 1204.86 lb/ft³
• Osmium, the densest element: 1410.24 lb/ft³

And here are some densities you might want to know:

• At 36 ft. tall while weighing 200 lbs.: 0.46 lb/ft³: a large sail, essentially, able to be pulled by the air
• At 1 inch tall while weighing 200 lbs.: 74 million lb/ft³: a super-ultra-turbo heavy bullet

(D) Independent Dimensionality

Rather than change size, you can now change a single dimension: length, width, or height. Thus, you could: change solely height and transform into Slenderman; change solely width and become Flat Stanley; change solely length and you become the best goalie in the world. 

Rather than cubing weight, you now just multiply it once (since it's only one dimension). 

Anything you swallow keeps the same relative dimension.

This one's a real wild one. There's a lot of math involved, so decide upfront how in-depth you want to get with the number-crunching. 

If anyone asks where the extra mass goes or comes from, say it's the Astral Plane.

Let me know how it goes.
