Here's a quick take on the missing 'Conan' primal path from 5e. There's an implicit sexism to Conan, which I've incorporated into the design. So go ahead and be a female Conan and rescue some prince or something. In this sense, it works pretty well as a kind of Amazon.
Stranger in a Strange Land
At 3rd level, when you adopt this path, you choose 2 bonus languages which you have picked up to survive (including abilty to read and write in those tongues). You gain a bonus language at 6th, 10th and 14th levels. Also, you are considered dangerous and strange by civilised men, gaining advantage on intimdation checks amongst them.
Cat amongst the Pigeons.
At 3rd level, when you adopt this path, you may enter a state of savage, uncaring joy when you make a Reckless Attack. After a successful hit , you may keep attacking as long as you keep hitting. Each hit after the first costs d4 hp, then 2d4 hp, then 4d4, then 8d4...(representing your lack of care for your own safety and defence). This state ignores damage resistance provided by entering a rage.
Beginning at 6th level, you gain advantage on attempts to seduce or command. Civilised enemies tend want to capture you, rather than kill (probably to torture you to death).
Stirred by Beauty
Starting at 10th level, you Crit on a 19 or 20 and apply an extra damage die to said Crit. This bonus only applies whenever you are attempting to protect, rescue or aid a member of the opposite sex.
Know, oh Prince...
At 14th level, you gain advantage on any stunt like manoeuvres when you rage. The stakes of a failed stunt, must always be high (DM's discretion) to qualify for this effect.
