Blunderbus Magus

[Aidulin]

I was wondering, with the eldritch archer archetype http://www.d20pfsrd.com/classes/base-classes/magus/archetypes/paizo---magus -archetypes/eldritch-archer-magus-archetype for magus, is it possible to use a blunderbus to deliver the touch spell to everyone inside that cone, because that would be a very fun character to play with and one can also do a lot of fun role play. One can also choose to first take one lvl in gunslinger to get a blunderbus for free and their first lvl abilities :)

I think by RAW you deliver the spell only to the first one you hit. Although, with multi-ray spells, this'd still mean you are doing some nice AoE damage on the side.

I'd take the first level in spell slinger, more fitting.

With a level dip Wizard(Spellslinger) you can channel your magus spell through your arcane gun first. Arcane gun says you can channel ANY spell through it unlike a Magus' spellstrike which specifically calls for a spell in the Magus spell list. So sack a wizard spell to enchant your gun +1 as a swift one turn, then swift another turn to +1 again with arcane pool. Then when your gun all beefed up, channel your Snowball spell(the ranged equivalent to shocking grasp) through your gun with a +2 to attack or +2 to save (but do mudball if you want a better reflex save maybe), then shoot your enemy in the head with a ranged spell strike. So its like throwing a snowball at kid's head with a rock in it...but the rock is a bullet. And we haven't touched ranged spellcombat yet so get ready to chuck another ro- I mean bullet at him. Now if you use ranged spell strike you don't attack vs their touch ac...wait a minute you do if you are in the first range increment with a firearm WHICH YOU HAVE.

Now if I am wrong in any of this rambling, please correct me.

(This "build"/theory craft is based on a Wizard1(Spell Slinger),Magus4(Eldritch Archer) so the numbers are sure to change)

Edit: Snowball has a saving throw effect for staggered. So if you want to raise the DC to that you can, but I think it's better to get the +2 to attack.

I just want to point out that even with multiple ray attacks, only one of the rays gets to affect one target if you cast it through spell strike, making most of the spell effect go completely to waste. Even though the blunderbus fires multiple projectiles this doesn't change.
