Let's say I were to create a level 5 gnome sorcerer, and they happened to pick Greater Mage Hand as a spell. Since I get to set the weight of the character, let's say they're 35 pounds, and less than 50 with gear.
The text of Greater Mage hand reads:
Target: One object or creature weighing up to 10 pounds per caster level
...
An object can be telekinetically manipulated as if with one hand.
Does this mean that a lightweight gnome could fly? If not, why not? If so, how can/should this be limited mechanically rather than by GM fiat? This is... beyond overpowered, if it is allowable.
