I just hit level 2 on my PFS Halfling Unchained Rogue, and I've decided to use the re-write to make him into a (nearly) full martial.
I'm staying Halfling so that's not changing, but I was thinking of a 1 level dip into Warpriest (Cayden) for the free weapon focus, first level blessings,divine spell(s), and damage die increase to offset the small weapon.
Dex to damage (probably rapier) will come online at 3, then the Deeds at 5.
I can't really see a big negative to the dip, but am I missing something?
Not posting full crunch because I haven't even started yet , but I'm not a fan of dump stats or going below 8 post racial, so stats will be close to 10, 17, 14, 10, 13, 15. (I know, I could leave the STR at 8 to boost the others, but I want some carrying capacity)
Personally I'd suggest going cleric and going the Crusader archetype as your lv2 to get weapon focus that way. You get one full domain which I feel is better than 2 blessings and that 1 point of damage between a d4 and d6 isn't enough to make it better than a good domain. Plus the cleric also gets a channel pool which can often be used somehow.
