Swordsmanship
Benimaru is a highly skilled swordsman, who can hold his own in a duel or a group in battle. Being named by Rimuru and his having constant training with Hakurou to improve his blade skills has caused him to grow exponentially. He is also capable of infusing his Extra Skill Black Flame with his sword giving his blade a massive power-up.
