I was talking to a few people and it seems we might get a game going either tonight or monday, likely monday but tonight is possible so I wanted to make up a character for this game. It could be a one shot, but I don't know yet.
I selected Barbarian//Monk
Using the Adopted Trait to pick up the Aasimar's Enlightened Warrior Trait to get out of LG monk.
The Archetypes are:
Barbarian: Serene (3pp) and Invulnerable Rager
Monk: Kata Master and Master of Many Styles, Qinggong is a possibility to trade out off things.
Race is a Kasatha, taking flaws to gain Multiweapon fighting for his unarmed strikes.
Now this is likely going to be level 5, due to us starting most at level 5 games.
If I didn't go monk and instead went Sacred Fist, which is possible how much would change really? I wouldn't gain access to master of many styles bonus feats for sure, but I would have access to spells.
Which is better?
Barbarian//Monk
or
Barbarian//Warpriest (Sacred Fist)
I think on the whole, you'll probably get more out of Sacred Fist casting than Monk stuff. You can cast spells while raging with Serene archetype, right?
While in a state of serenity, a barbarian cannot cast spells, use Intelligence-based skills, or communicate.
Unfortunately it seems like the 3pp just copied and pasted the Rage ability and changed names. Though I think my DM would allow for that to be changed (After all if you are all zen why wouldn't you be calm enough for spell casting)
Either way, you can swift action buff with warpriest spells, then free action rage, then do whatever you want for a fight. If Serene gets to cast spells it's even better, but I say Sacred Fist either way.
