I'm looking to make a switch hitting kind of character, and I'd like to be able to make a ranged attack as a class ability. Ideally, I'd like to be able to reliably hit multiple enemies at short range for a little bit of damage, with some sort of debuff attached, but I'm open to compromise.
I know Alchemist would be a great choice, but I'm trying to avoid duplication. I'm looking to start at 3rd level.
The only thing I can think of is the battle scion from kobold press and specifically the force blaster archetype for it. Its a full bab 4 level arcane caster class that gets the 'force blast' class ability. Ranged touch attack, that does scaling damage and with the archetype can knock opponents prone. At 2nd level you can fire 2 a round (becomes a move action) at 10th level you can fire 4 a round (2 per move action)
