One of my players is playing an alchemist and he plans on combining the alchemist's Int damage bonus for bombs with focused shot. Both add your Int mod to damage, so does that count as the same source? Would this be the same as a bow and arrow with their enhancement bonuses? To use the feat he plans on taking the discovery which lets him add a bomb to a bolt or arrow.
On a direct hit, an alchemist's bomb inflicts 1d6 points of fire damage + additional damage equal to the alchemist's Intelligence modifier.
As a standard action, you may make an attack with a bow or crossbow and add your Intelligence modifier on the damage roll.
