Here's something for the Fighting-Madness feat (strongly suggested for the Cimmerian Barbarians). Check this out. It's from Queen of the Black Coast.
To review the scene: Conan's merchant ship is being attacked by pirates. They're in the Great Western Ocean, off the coast of Kush. The pirates have a massive 80-oar coast line raiding vessel with a metal ram on the bow. Conan is in a 10-oar light merchant craft that skims the shoreline and travels up-river for trading.
The pirates first take out the merchanman's rowing men with sheets of arrows. Once Conan's ship loses enough men, the ship goes slack in the water. The pirate vessel rams it, with the pirates throwing grappling hooks tied to ropes to catch the merchantman and allow for boarding.
This is when Conan jumps to the pirate ship, sword in hand, teeth bared, determined to spill some blood.
From Queen of the Black Coast, Chapter One: In an instant, he was the center of a hurricane of stabbing spears and lashing clubs. But he moved in a blinding blur of steel. Spears bent on his armor or swished empty air, and his sword sang its death-song. The fighting-madness of his race was upon him, and with a red mist of unreasoning fury wavering before his blazing eyes, he cleft skulls, smashed breasts, severed limbs, ripped out entrails, and littered the deck like a shambles with a ghastly harvest of brains and blood.
