I'm working on creating a character for Pathfinder, he is a gnomish wizard and the "Alternate Favored Class Bonus" says:
Select one arcane school power at 1st level that is normally usable a number of times per day equal to 3 + the wizard’s Intelligence modifier. The wizard adds +1/2 to the number of uses per day of that arcane school power.
When creating a Gnomish Wizard the favored class bonus says to add +1/2. I don't understand what it means to add +1/2 to the number of uses per day?
