I'm trying to create a ranged character that makes custom bows (i.e. arm-mounted arrow-launchers) and fires a single powerful arrow from them each round in combat. He would be either an Android (from inner sea bestiary) or a Human.
I think my only options to accomplish this are:
1. Fighter /w Vital Strike chain (as far as I can tell this is extremely sub-par compared to a Manyshot build), possibly with a level of Wizard or Sorcerer into Arcane Archer.
1d8*Number of Attacks + Deadly Aim, Weapon Training, Weapon Spec, etc.
2. Myrmidarch Magus using Ranged Spellstrike using Snowball/Reach Shocking Grasp, limited by spells per day (acquired at level 4).
1d8 + between 4d6 and 15d6 (empowered / intensified)
3. Grenadier Alchemist using Explosive Missile and ideally Targeted Bomb Admixture (acquired at level 4). Limited by Bombs per day, but can use alchemical splash weapons in a pinch for backup or against weaker enemies.
1d8 + between 2d6 and 10d6 + INT with a bomb
1d8 + between 2d6 and 10d6 + 2*INT with Targeted Bomb Admixture
1d8 + 1d6 + INT with Alchemical Fire
Any of these could benefit from Kirin Strike (+2*INT damage to an attack as a swift action if you have identified the target using Kirin Style) but that isn't until level 9 and takes 3 feats, or it takes a 2 level MoMS monk dip, holding back spell progression for magus or holding back bomb progression for the alchemist.
I think the fighter Crossbowman archetype might be useful here, but I'm not sure what the intent is when every feature says "when a crossbowman attacks with a crossbow as a readied action" ?? Can I ready an action to attack a certain enemy as soon as my turn ends? x.X
Which of these do you think is most viable? Or, does anyone have any recommendations for how to do this besides what I have found so far?
Note: I'm not wanting a stealthy character, so I'd prefer to not have the solution involve sneak attack (not that ranged sneak attacks are particularly viable).
