Im helping a friend build their first Sorcerer in Pathfinder. We have decided to take the Arcane Bloodline. While I am not used to playing a magic user, I am GM every other weekend with my group. I have always been a little shaky on the way some of the magic works.
The Arcane Bloodline gets an Arcane Bond like a Wizard does. This allows a wizard to cast a spell from his spell book without having to prepare it in one of his spell slots ahead of time. The sorcerer is a spontaneous caster. The Sorcerer's bloodline Arcane Bond says:
Once per day, your bonded item allows you to cast any one of your spells known.
Then what is the point of that feature, and how does it work? My player has a choice between using a familiar or a bonded item.
Can the sorcerer cast a spell they know without using a spell slot? They already cast any spell that they know at will, as long as they have the slot to use it. What's the benefit?
