Viper is VAMPIR's orb-wielding magic and curse class: Netmarble's Korean guide gives its keywords as "orb, magic, curse" and describes it as the ancient sorcerer who controls the battlefield; the official global site calls it "a vampire sorcerer who controls the battlefield using ancient sorcery" and says wherever Vipers appear becomes tainted with poison and curses. Pick it if you want to control space and weaken enemies rather than trade blows.

How Netmarble introduces Viper

The official global class page sums it up in one line: "A vampire sorcerer who controls the battlefield using ancient sorcery." The longer description reads: "The Vipers are considered dangerous beings even among vampires. Through rituals, they transform the power of darkness into curses. Their sinister, cursed power turns them into the most threatening entities in Nocturne. Wherever the Vipers appear becomes tainted with poison and curses, which fills the world with death." It is lore, not numbers: nothing in it is a skill value.

Viper weapon and keywords (Korean guide)

The entry in Netmarble's Korean class guide
FieldValue
Weapon Magic orb
Keywords Orb, magic, curse
One-line role Ancient sorcerer controlling the field with dark curses

The Korean guide gives each of the five classes one weapon and three keywords, and no skill list or numbers. For Viper those three words are enough to place the class; read the actual skill text on the skill screen in your own client.

This mapping is a reading of the official text, not measured damage, survival or ranking data. Before you commit, run the 30-minute test from our class-choice guide.

What to watch in your first 30 minutes with Viper

  1. Finish the tutorial and open the skill screen: check whether the skills that come with the magic orb match the keywords "orb, magic, curse".
  2. At the same farm spot play five minutes on auto and five minutes manually; note which mode loses less HP.
  3. Play until you die once and write down why: something that closed the distance, or damage from range? The answer tells you whether this class fits you.
  4. Watch the bloodsucking icon and the adrenaline gauge; those two mechanics change every fight regardless of class.

Picked wrong? Class change

According to the Korean class change guide the change is done in town only; one form, up to three weapons and every skill you own can be converted, and extra cost can apply depending on what you select. Deciding before forms and weapons pile up keeps that bill small.
