You should mix me up a growth drink, Doc! I'm afraid that the limits of my sexual prowess will be severely hampered by my less then 6" tall stature.
Umm... Well... No, I must have heard you wrong. 'Prowess', yes, that was what you said. Prowess. I am an expert in increasing my costumer's battle prowess. I can provide several temporary measures that may help you with your conundrum. This fine concoction right here should increase your height by a factor of twelve, while keeping everything else proportional, including strength. Since sprites are stronger per-ounce than humans, this will grant you enormous power for whatever quarrel you wish to settle. It is a pity it only has such a drastic effect on the smallest of the small folk like yourself, honoured client, or else I could use its power to create an army of invincible giants. For two hours, give or take a few minutes, that it.
