Well Elsword as his Infinite Sword class has the Conwell. A sword that allows him to summon an unlimited amount of duplicate swords at will. Though at the cost of some magic (and it's balanced in game so... yea. Though if you look at his Hyper Active in Korea...
holy sh*t...)
Elsword is also described as being hot-headed, prefers action over talking, is a bit cocky when it comes to his skills, and due to the Dark El that Elsword absorbed to unleash the full power of Conwell (though the only negative effects it had on Elsword was turn part of his hair black, and make him a bit more fierce in battle...) is a bit reckless in battle. His swordsmanship is pretty high, and due to his ability to summon a multitude of Conwell's to attack his opponent up close, or at a distance is a serious threat. Can be considered more of a threat than Tactical Trooper Chung, or Veteran Commander Raven due to the Conwell's power, but he also has the skill to dual-wield swords (in game his combos are quite long. Usually involving Elsword performing long barrages of slashes, or combos that lead up to him summoning multiple Conwell to damage foes.)
I just picture his recklessness in battle, and his temper getting him into trouble. Elsword does mean well... he just... is bad at being you know... thoughtful at times. In fact in the story of Elsword the Character Eve (the Queen of Nasods) woke up from her chamber after who knows how long (thousands of years being preserved in a capsule), and the first thing she did was slap Elsword
