I'm new to Pathfinder, and I never did much 3.5e before that.
I'm slightly confused by something that seems to pop up in the advanced players guide. Lots of the races can pick special favoured class options and many of these are along the lines of with "+1/2 to the number of thingies you can cast/use/create/damage"
Does this mean that for every 2 levels you take you get a +1 bonus? Do those +1/2 points do anything on their own? Is it added as a percentage (which seems abusive) or a number (which seems week)?
I feel very confused over this area. Can someone enlighten me?
