kill-knight-bernahl

It seems you might be referring to two different things. "Kill Knight" is the name of a game, while "Bernahl" is a character in Elden Ring.

In Kill Knight

There is no specific character named Bernahl. Kill Knight is an action shooting game. In the game, players control a knight who has fallen into the abyss and become a walking corpse. The knight's only goal is to kill the final angel hidden in the shadow of death235.

In Elden Ring

Bernahl, also known as "Recusant Bernahl", is an NPC in Elden Ring. He first appears at the Hut of the Lost Graces in Limgrave. Later, players will encounter him again in the Volcano Manor and the Crumbling Farum Azula. He has his own questline, and players can buy Ashes of War from him and learn combat skills. If players kill him, they can obtain items such as the Profane Beast Claw, World-Eater's Staff, and the Beast-Gathering armor set.

Kill Knight is an arcade-inspired action shooter with an oblique 45-degree view that tests your reflexes. Relegated to the eerie depths of the gladiatorial abyss and subjected to endless trials and tribulations, you must utilize an array of destructive weapons to destroy the hordes of otherworldly monsters that come your way, all the while keeping one thing top of mind - conquering your inner demons.
