Short answer

Viper is VAMPIR's curse caster. It fights with a magic orb, controls the field and weakens enemies instead of trading blows; Netmarble's keywords are orb, magic and curse. Who it suits, the official lore and class video, and how a class change works.

How does Netmarble describe Viper?

Netmarble's global class page calls Viper "a vampire sorcerer who controls the battlefield using ancient sorcery." The lore: Vipers are seen as dangerous even among vampires. Through rituals they turn the power of darkness into curses, which makes them the most threatening beings in Nocturne, and wherever they show up, the ground is left tainted with poison and curses. Great flavour, but no skill values.

What to watch in your first hour

Viper is about control, not trading hits. On the skill screen, find the skills that curse or weaken a target and open with those, then check the range on each one yourself. Keep an eye on the bloodsucking icon and the adrenaline gauge too: every class has them, and they change how long you can stay in a fight.

Can you change class later?

Yes, in town only. Netmarble's Korean class-change guide lets you convert one form, up to three weapons and every skill you own, and extra costs can apply depending on what you pick. The fewer forms and weapons you've built up, the cheaper the switch, so decide early.

FAQ

Is Viper a ranged class in VAMPIR?
It's a caster that fights with a magic orb, but Netmarble's keywords (orb, magic, curse) don't say ranged. Carnage is the only class with ranged in its keywords. Check each skill's range on the skill screen.
Can Viper heal?
Nothing in the official class text says so. Its keywords are magic and curse. If you want to play support, Arena lets every class pick a tank, healer or damage trait at the start of each match.
Is there an official Viper tier list?
No. Netmarble publishes lore, a weapon and three keywords per class, with no damage numbers or rankings.
