"I am going to try a curse. The next liquid you are within 10 feet of you will transform into for 12 hours. At the end of your curse you get a reward. You get to curse the nearest human (no wizards) to you. She/he cannot be the form you were in. They can be any other liquid or something of other form. Afterwards you will be transformed into a wizard like myself." explained Ken. You fell asleep.
You woke up feeling normal but you had to pee. "Oh shit! Liquid!" You try to run but you become liquidy as your bones disappear. Overwhelmed, you faint.
You wake up again with a stench and a yellow coloration. 'I am piss!' you thought until you realized you can no longer speak, just think.
"New Movie Idea: 12 Years a Puddle of Piss" laughed your wizard roomate.
