Hi! I am late to the party but recently made an Alchemist build that I am very eager to try out in case my main character dies!
Ysoki (Ratfolk), Alchemist (Mutagenist) with Warrior Background. I wanted to create a Witcher-like Pathfinder character that uses his alchemical concoctions to aid himself and allies in battle.
I balanced out the starting stats with 14 in STR, DEX & CON, 16 in INT and 10 in WIS & CHA. This gave my L1 Kric decent AC and attack for bombs and melee + more uses of my infusions.
At L2 I took the Fighter dedication to become trained in Martial weapons (choosing to dedicate to Axes), becoming somewhat okay in a wide variety of skills!
L3 - Toughness, staying longer into battle is great
L4 - Archetype feat - Opportunist for AoO
L5 - Ability boosts to STR, DEX, CON (16) and one to your liking. INT for 18 is always great, WIS or CHA for boosting other skills is also neat!
L6 is where I left the build because we did not go higher with main character, but is the 'Oh, more HP? Neat.' Fighter Archetype feat 'Fighter resiliency' grants additional HP for every fighter feat you have
By now you can slash, splash and craft pretty well! In comparison to my main at L6 Champion, this build is has +1 HP, -1 AC and -3 to hit (PB) BUT is an absolute skill monkey and has a lot of utility with crafting!
I hope this helps to inspire others into taking a concept that you like and making it your own! Kric Humblebrew may be based on the legendary Witcher, but he sure is his own entity!
