Cap'n Kobold
Hero
How often does he actually use the whip as a weapon though? I can't recall him killing anyone with it other than accidently hanging an opponent with it once.Issue is for whip he needs a feat or a class with martial weapons to use one so he would have to add some fighter be the easiest and Human variant and take tavern Brawler because Indy got into a lot of fist fights
Whip proficiency isn't required I think.
I think people are looking at a non-magic build.I'm the guy who thinks Indy could use a few levels of Monk for his fisticuffs and unarmored AC. Basic ki usage like disengage or dash and dodge as well as increased movement (he books from people chasing him all the time).
In the films, people don't tend to wear armour due to the time period that they're set in. I can see a fantasy version of Indy using light armour not problem.
Rogue levels (with a bit of tweaking to the SA rules if you haven't already) would explain his ability to sucker-punch guards to take their uniforms easily, but need protracted fight scenes with any non-mook opponents that he can't take unawares.
He is also a bit higher level than most of the people that he fights, so can win a punch-for-punch fight a lot of the time.
