Destroyer, Twin Silver Shooters
The Deadly Chaser is none other than Chung Seiker; a character from the Elsword online game.
After compiling the strengths of both the Silver Shooter and the Destroyer, Chung succeeds in forming two Silver Shooters. This results in Chung able to use his Silver Shooters more conveniently at any time with his new plethora of skills also being able to both disable the opponent while attacking from a suitable distance. Any incoming enemies approaching him can easily be wiped in a blink of an eye, acting as a sniper in any fight. The Deadly Chaser is surely a force to be reckoned with in the battlefield. Those who are fighting one should always be cautious, as they can instantly get shot without even realizing it.
The powerful bullets launched from the pair of Silver Shooters overwhelm their enemies and diminish their morale even before they sense Chung's presence. When opponents see the light ahead, they quickly find themselves looking up at the sky. This new method of fighting gave Chung the image of an "Assassin" rather than a "Guardian". From then on, people began to call Chung -- the tracker of death, the one who can hide even his shadow, the Deadly Chaser!

Every character in Elsword has his/her unique features that sets them apart from other characters.
Ammunition, Ammo, Cannonballs, probably the most notable and interesting aspect of Chung is his Ammunition Supply. Nearly all of Chung's skills rely on his ammo. Skills such as Detonation or Lunatic Blow can use up all of Chung's ammunition, but at a good price, considering that the amount of power for these skills, is multiplied by how many cannonballs Chung currently has. Other skills such as Aiming Shot or Steel Edge uses only one. Some skills though, like Iron Howling or Dual Buster don't use any ammunition at all. But that doesn't necessarily mean they're bad, they're for other situations. In fact, skills aren't the only things that uses up Chung's ammo, many of his X attacks use them too! In order to reload for your ammo, just stand still, and Chung will set down his cannon and quickly add more cannonballs, you can also reload by using certain moves. It should also be known that Shooting Guardian has a very useful Passive that will double his ammunition count. If you do not have any ammunition, you will not be able to use any skills that require cannonballs. Therefore, it should be heavily recommended that you always carry at least 1 or 2 rounds of ammunition just in case at all times.
Awakening Bead Edit
Like all characters, Chung also has his own Awakening Beads. But his awakening function sets him apart. His 3rd awakening bead at first glance, looks like its locked, with chains covering it. The way to unlock it is just like unlocking other awakening beads, getting enough hits. The main reason it looks different is to show you that your Berserk Mode is ready and fully functional. It should be known, however, that Chung cannot reach his Berserk Mode if he has 2 or less beads filled. Having 2 or less beads filled will only have him reach a normal awakening mode just like the other characters, with the exception of his armor and ammunition supply.
Berserk Mode Edit
This is probably the most powerful aspect of Chung. His Berserk Mode. Not only does Chung gain a slight boost in his attack strength and skills, but more importantly, Chung gains Unlimited Ammunition. This means that he has limitless ammo and skills that normally use one or two, or even all your cannonball supply don't effect your ammunition count. However, it is wise to use his Awakening Mode only at desperate times or when getting prepared for a boss battle. It will take a while for you to achieve Chung's berserk mode again, and his form only lasts for 90 seconds without any awakening time modifiers.
