Content warning

Unlock details differ between mobile editions and Steam. The game page confirms a 16-hero roster, but the complete stage-by-stage mobile pricing and unlock data is not presented in one official source. Where community reference data fills that gap, it is identified as such.

The answer before the background

Our recommendation

Kingdom Rush Origins has 16 playable heroes: Eridan, Arivan, Catha, Razz and Rags, Lilith, Reg'son, Prince Denas, Xin, Lynn, Vez'nan, Durax, Bravebark, Bruce, Phoenix, Wilbur, and Faustus. On mobile, Eridan is available first, while Arivan, Catha, Razz and Rags, and Lilith are unlocked through campaign progress; most others are paid heroes. Steam uses campaign-stage unlocks instead. Hero levels are temporary within a stage: active combat earns experience, levels rise to 10, and the progress starts over when the stage ends.

All 16 playable heroes and their practical roles

The roster covers ranged damage, crowd control, melee holding power, support, and high-impact specialist abilities. The role labels below are practical recommendations based on each hero's published identity and documented combat profile, not official class names.

Every hero can fight anywhere on the path, but the best placement depends on whether the character is built to hold enemies, destroy groups, support towers, or attack safely from range.

  • Eridan, the Ranger: dependable ranged damage and a strong starting hero. He is a safe all-purpose pick for learning maps.
  • Arivan, the Elementalist: ranged elemental attacks and control. Keep him away from heavy melee pressure and use him against clustered enemies.
  • Catha, the Pixie: mobile support and control. She is useful when a map rewards quick repositioning and disruption.
  • Razz and Rags, the Rag: a durable two-character melee option suited to holding a lane and buying towers time.
  • Lilith, the Fallen Angel: a flexible fighter with dark-themed damage and survivability tools. She works well as a roaming problem-solver.
  • Reg'son, the Eldritch Blade: fast melee damage. Use him to intercept dangerous targets rather than leaving him idle at the back.
  • Prince Denas, the Noble Knight: a defensive frontline hero who is comfortable beside barracks and other blockers.
  • Xin, the Panda Monk: a melee specialist with unusual martial-arts abilities. He rewards close control and deliberate target selection.
  • Lynn, the Hexblade: a damage-focused melee hero with curse-style utility. She is best when actively moved between threats.
  • Vez'nan, the Dark Wizard: ranged magic, area control, and a demon-focused toolkit. Protect him from direct attacks.
  • Durax, the Elemental: a teleporting specialist who can pressure several points of a map. He is excellent for players who like constant movement.
  • Bravebark, the Ent Lord: a heavy melee hero with strong burst potential and teleportation. Place him where a large enemy or lane needs immediate attention.
  • Bruce, the Werelion: a durable close-combat bruiser. He is a straightforward choice for bosses and dense enemy packs.
  • Phoenix, the Eternal Bird: flying damage and repeated pressure. Her mobility makes her useful when normal path access is awkward.
  • Wilbur, the Inventor: ranged damage with a technology-focused toolkit. He is strongest when positioned safely behind the frontline.
  • Faustus, the Dragon Mage: a high-damage ranged specialist. Keep him protected and let his spells handle priority targets and groups.

Recommendation, not a ranking

For a first playthrough, Eridan is the safest generalist, Arivan is a strong ranged-control choice, and Vez'nan or Faustus are attractive paid specialists. No single hero is mandatory because tower placement and stage rules matter more than a universal tier list.

Mobile versus Steam unlocks

On mobile, the first five heroes are the important progression group. Eridan is available at the beginning. Arivan, Catha, Razz and Rags, and Lilith are associated with campaign progress. The remaining heroes are presented as in-app purchases in current store listings, although the exact package and price can change by edition or region.

Steam is different. The community roster reference records heroes being unlocked by reaching stages rather than buying individual mobile DLC. The broad pattern is simple: early heroes appear during the main campaign, while many premium-era heroes become available at Shrine of Elynie.

  • Mobile progression: use Eridan first, then expect Arivan, Catha, Razz and Rags, and Lilith through campaign milestones.
  • Mobile purchases: current United States Apple listings explicitly show purchases for heroes including Vez'nan, Faustus, Phoenix, Bravebark, Xin, Reg'son, Bruce, Prince Denas, and Wilbur.
  • Steam progression: Eridan is available in Gray Ravens, Arivan in Waterfalls Trail, Catha in Gryphon Point, Reg'son and Prince Denas in Grimmsburg, Razz and Rags in Neverwonder, and Bravebark in The Unseelie Court.
  • Steam late roster: the reference lists Vez'nan, Xin, Phoenix, Durax, Lynn, Bruce, Lilith, Wilbur, and Faustus at Shrine of Elynie.
  • Do not assume a mobile purchase is required on Steam. Check the hero screen for the edition you own before spending money.

Verified versus uncertain

The 16-character roster is confirmed by Ironhide's official game page. Mobile purchase availability is confirmed by current Apple listings. The detailed Steam stage mapping comes from a maintained community reference rather than an official publisher support article, so treat it as the best available reference and verify in-game if your build behaves differently.

How hero XP and temporary levels work

Hero leveling happens during a stage. A hero earns experience from active combat, grows stronger during that battle, and can reach level 10. This is not a permanent account progression system: when the stage ends, the combat level does not carry over as a permanent hero level.

The practical goal is therefore to get the hero into combat early, keep the character attacking, and avoid long periods of standing outside attack range. A defeated hero respawns after a delay, but that lost time reduces opportunities to gain experience.

  • Deploy the hero as soon as the stage allows it, then move the character into a safe attack position.
  • Use active abilities when they are available. Community testing and player reports indicate that abilities contribute meaningfully to experience gain, but the exact formula is not documented by Ironhide.
  • Keep the hero near enemies without allowing unnecessary deaths. A frontline hero can fight beside barracks; a fragile mage should attack from behind them.
  • Choose a later, repeatable stage where the hero can reach many enemies. Community reports commonly recommend later campaign areas such as The Unseelie Court or the Ancient City stages.
  • Use Casual difficulty when farming if your priority is reliable completion rather than challenge. The exact experience-rate difference is not officially documented, so treat this as a practical community recommendation, not a guaranteed multiplier.
  • Do not expect every hero to reach level 10 every time. Enemy density, map layout, difficulty, hero survivability, and time spent attacking all affect the result.

About the XP table

These cumulative thresholds come from a Steam community data guide that cites game-file research, not from an official manual. They are useful reference values for the Steam build, but the publisher does not publicly document the complete XP formula or guarantee that every platform uses identical values.

Vez'nan, best picks, and fast leveling answers

Vez'nan is a playable hero in this prequel even though he later becomes one of the franchise's major villains. In Origins, he functions as a fragile ranged magic specialist with strong crowd-control potential. Protect him with barracks or reinforcements, then use his spells against groups and high-value enemies.

There is no universally best hero. A hero that looks powerful on one map may be less useful when the stage restricts movement, introduces flying threats, or demands a specific damage type. Choose by job: Eridan or Arivan for dependable ranged play, Denas or Razz and Rags for holding a lane, Durax for mobility, and Vez'nan or Faustus for protected spell damage.

For fast leveling, repeat a late stage on an easier difficulty, place the hero where attacks are constant, cast abilities promptly, and prevent deaths. The game does not provide a permanent hero-XP grind in the modern RPG sense, so farming means improving the hero during the replayed stage rather than permanently raising a profile level.

  • If you want one safe starter: use Eridan.
  • If you want a ranged controller: try Arivan.
  • If you want a frontline blocker: try Razz and Rags or Prince Denas.
  • If you want movement-heavy play: try Durax or Bravebark.
  • If you want the named Vez'nan hero: look for him in the mobile hero shop or the later Steam unlock path.
  • If you want quick combat levels: use a later stage, easy difficulty, constant attacks, and frequent ability use.

Common questions

Are all heroes free in Kingdom Rush Origins?

Not on every platform. Mobile editions use a mixture of campaign unlocks and paid hero purchases. Steam is documented as using campaign-stage unlocks for the full roster. Check the store and the in-game hero panel for your specific edition.

How do I level up heroes fast?

Replay a later stage that gives the hero frequent attack opportunities, select an easier difficulty for consistent clears, use abilities as soon as they are ready, and keep the hero alive. There is no permanent account-level grind; the hero levels during the current stage.

Does Vez'nan start as a villain?

No. Origins presents a younger Vez'nan as a playable Dark Wizard before the later events that establish his villain role. His story position is one reason he is a distinctive hero, but his gameplay still requires protection because he is comparatively fragile.

Which hero should a new player use?

Eridan is the safest first choice because he is available early and provides reliable ranged damage. Arivan is a good alternative for players who prefer elemental control, while Razz and Rags or Prince Denas are better for a direct frontline approach.

Are Alleria, Malik, and Bolverk playable heroes?

They are named characters associated with Origins content, but they are not included in the 16-hero selectable roster listed by the official game page and the maintained roster reference.
