You flick through the pages and the first set of spells you land on are for muscle growth.
"This could be interesting" you think to yourself.
Excited, you read on. You notice one spell entitled 'Step up' and read the explanation below.
'Once cast this spell will make the target gain 10lbs of muscle mass with every step he takes'
"Oh man I've got to try this one." You read on for the incantation.
"Encron Musculos Amulo" you cry.
You don't notice anything, but since you won't know until you start walking you go to the bathroom.
Immediately it hits you - 1, 2, 3, 4, 5. You once 200lb body has ballooned to 250lbs. You look in the small bathroom mirror and look upon yourself, but can see the extra muscle packed onto your frame has thickened you neck, even your jaw. You look down on you body and watch your new found muscle ripple under paper thin skin.
"I've got to get to a bigger mirror"
You run into the living room to take a look at yourself in the large mirror there, and again it hit you...although the walk is slightly longer this time, 20 steps exactly.
"Man, I think I over did it a bit" you giggle to yourself.
Looking upon the 450lb body reflected back in the mirror you amuse yourself by exploring how musclebound you've now become. You try turning what used to be your neck but huge trap muscles have firmly planted your head looking forward. You try to scratch an itch on you nose, but a massive arm and chest soon ends that idea. You attempt to bend at the waist to look at you new huge legs but again fail.
Just then a dreadful thought ran through you, "how do I deactivate the spell?"
