Lolol. Anyways, I've got the specifics of the spell Polymorph: Random, as well as the 'Potion of random transformation'

Notes: Random potions and forms
A general overview of the random forms 
1-3 = terrible form (bugs, slugs, ect. Must NOT have any sort of poison or any way to harm anyone to be in this category.) 

4-30 = bad form (usually passive animals, small, non-insect animals, farm animals, may not have any sort of poison or magic.) 

31-60 = neutral form (minor mystical creatures, other PC races) 

60-99 = good form (most mythical creatures, giants, minotaurs, ect) 

100 = dragon.

The victim of the potion also have to flip a coin to determine the gender of their new form 
Heads = same gender as character
Tails = opposite gender of character

Another note: some of the transformations cancel out/destroy/may get killed by wearing armor (clothing doesn't count, but, say, leather might [though leather and weaker armors have a very small chance of killing, whereas steel or heavier metal armors have a high chance of killing through larger transformations.)

This potion may permanently transform (non-teammate) NPCs, but not PCs.
