As of now, there are currently six classes in Revelation Online.
The classes of Revelation Online are:
Gunslinger: With high precise damage they hunt down individual targets from afar or use advanced weaponry for mid-range deterrence. Gunslingers have few control skills and are less effective in close combat.
Blademaster: As secondary tanks and close combat specialists they combine their twin blade damage with escape skills allowing them to cut through wave after wave of enemies. Their heavy reliance on melee attacks leaves them open to ranged attacks.
Spirit Shaper: As summoners and healers they are relatively easy to play and have great survival skills. They are highly sought after on teams for their support and deceitfully high damage output.
Vanguard: These steel walls rely on melee combat. Their chief strength is surviving battles of attrition, rather than dealing burst damage.
Swordmage: While wielding a falchion they are focused on powerful magic damage, specializing in area of effect spells. They invest all of their energy in sharpened elemental magic, leaving them relatively vulnerable to focused attacks.
Occultist: They deliver a wide variety of dark offensive spells, from damage-over-time, to area-of-effect attacks, to those that deal damage while siphoning enemy health. Occultists can directly heal allies as well.
