Boomy here is my PFS leshy shootist.
But I can't decide what class and archetype to use to give him Gunsmithing, necessary for the purchase of guns in PFS. The Savage Technologist barbarian archetype does not give access. Here are my options.
1. gunslinger (no archetype); advantages are Quick Clear deed, and WIS based grit so better Will save (I can rebuild to adjust CHA and WIS)
2. gunslinger with Mysterious Stranger archetype: advantages are CHA based grit and CHA to damage with guns (by spending grit). CHA synergises with Mouser swashbuckler, which is a part of this build.
3. spellscar drifter cavalier: advantages are CHA based grit, Quick Clear deed via Amateur Gunslinger, a 1/day challenge and a mount I won't use
I only need one level of any Gunsmithing class - I'll take 5 levels of Savage Technologist barbarian for DEX to damage with guns.
If I go with vanilla gunslinger, there is an option of taking the techslinger archetype later if I play the right module. If I choose one of the CHA based options, techslinger would be less effective.
The chief mechanical goal here is getting into the enemy's space with Mouser underfoot assault and unloading firearms point blank. Any of these 3 options will achieve the goal. The comparison is between different grit/panache configurations, Quick Clear vs Focused Aim, and higher CHA or WIS.
