Immortal Codex throws a lot of gods and monsters at you very quickly, and most of them look viable in the first few chapters. The problem is that resources tighten up as you move into the mid and late game, so dumping gold, experience, and duplication materials into the wrong units can stall your account for weeks.
The characters below are grouped into four power bands. The S tier highlights units that stay valuable in nearly every mode once built. A tier covers strong picks that may be a little more niche or team‑dependent. B tier contains serviceable options that are often replaceable. C tier are the mythic units you generally park on the bench unless you have an immediate hole to fill.
How team building works in Immortal Codex
Each team uses five characters drawn from your roster. The basic structure is familiar from other idle RPGs: you want a mix of damage dealers, frontline durability, and backline support.
- Damage dealers are usually Mages, Marksmen, and Assassins. They clear waves and finish bosses.
- Frontline is handled by Tanks and some Warriors. They soak hits and hold enemy formations in place.
- Supports heal, shield, or buff your main carries and often decide whether a fight snowballs in your favor.
On top of classes, every unit has a suit color. Placing heroes from matching factions unlocks extra stats, and a common target is a “3+2” setup: three heroes from one faction and two from another. That bonus matters, but it should not override core synergy. A poorly synergized mono‑faction team will lose to a well‑constructed mixed lineup that happens to land a 3+2 bonus.
Lower‑rarity units can be promoted, but they are meant as early‑game scaffolding. Mythic characters get up to five abilities and scale much harder, so long‑term planning should always revolve around them.
S tier: meta‑defining characters
S‑tier units are the backbone of the strongest teams. They are efficient investments: once you commit to building them, they continue to perform from early game all the way into the hardest content.
| Character | Role | Why they are S tier |
|---|---|---|
| Fengyi | Clubs – Mage | Powerful, easy‑to‑trigger area damage, stacking self‑buffs, and given to every player at the start, which makes her a cornerstone free‑to‑play carry. |
| Freya | Clubs – Support | Extremely strong single‑target and team healing that prioritizes injured allies, a continuous‑healing ultimate, and passive damage reduction through her Artifact. |
| Athena | Diamonds – Support | Frontline support that mitigates damage, stuns, heals, and increases both damage and survivability, built around a persistent shielding aura that scales over the fight. |
| Zeus | Starlight – Mage | Hybrid single‑target and AoE nuker who fills the screen with clones and scales hard with buffs through his Overload stacks. |
| Amun‑Ra | Starlight – Warrior | Frontline bruiser with teamwide opening damage reduction, strong attack debuffs, and an ultimate that turns him into a burst damage engine. |
| Nyx | Starlight – Assassin | Backline assassin that teleports at the start, stuns and shuts off energy gain, then cycles huge single‑target damage while becoming untargetable during her ultimate. |
| Isis | Hearts – Marksman | Simple but extremely high DPS kit with ramping attack speed and extra arrows tied to basic attacks, which scales brutally with any external attack speed buffs. |
| Nemesis | Spades – Assassin | Mobile assassin with frequent dashes, a damage‑boosting passive that procs often, and an ultimate that makes her untargetable while carving through multiple enemies. |
| Nuwa | Starlight – Tank | Unique tank whose three golems cover tanking, healing, and damage; she also spreads large shields, giving her unmatched flexibility in almost any team. |
These characters cover every core job: wave clear (Fengyi, Zeus), single‑target burst (Nyx, Nemesis, Isis), defensive core (Nuwa, Athena, Amun‑Ra), and sustain (Freya). If you are deciding who to pull for or ascend first, prioritize at least two of them: one primary damage dealer and one defensive or support anchor.
A tier: strong but slightly more situational
A‑tier units sit just below the absolute best. They either specialize in certain modes, want more investment to shine, or share their niche with an S‑tier character who simply does it better. They are still excellent pulls and can absolutely carry accounts that have not lucked into multiple S‑tier heroes.
| Character | Role | Notable strengths |
|---|---|---|
| Anubis | Clubs – Assassin | Reliable physical burst with multiple stuns, a high‑damage execute ultimate that refunds energy on kill, healing reduction, and a self‑save that makes him untargetable at low HP. |
| Poseidon | Spades – Warrior | Sturdy frontline with crowd control and frequent shields; high energy generation lets him spam a damaging, knockback ultimate, and his Artifact lets him open fights with it. |
| Demeter | Clubs – Tank | Heavy mitigation through stacking damage‑reduction, energy‑stealing damage, and thick self‑healing and shields on a crowd‑control ultimate. |
| Dionysus | Starlight – Support | Wide buff package on ultimate (attack, speed, energy regen, movement, cooldown reduction) plus resistance scaling with class diversity and evasive, healing‑focused basic behavior. |
| Hecate | Spades – Mage | HP‑based sustained damage with built‑in lifesteal, a large lingering AoE ultimate, and a backline‑targeting stun. |
| Momus | Spades – Tank | Reliable taunt ultimate, decent damage and knockdowns, plus repeated shielding and a built‑in “fake death” that replaces him with a clone once. |
| Artemis | Clubs – Marksman | High damage with strong self‑defense; gains massive dodge when focused and a super‑armor DPS window through her ultimate. |
| Ares | Diamonds – Tank | Classic bruiser tank that hits harder when low, shreds armor, becomes heavily damage‑reduced and CC‑immune with his ultimate, and ignores a killing blow once per fight. |
| Phoenix | Diamonds – Marksman | Risk‑reward marksman whose damage rises as HP falls, with self‑healing and self‑revive baked into the kit; devastating with proper support. |
A practical way to think about A tier is synergy. Anubis, for example, pairs well with any comp that wants extra crowd control and finishing power on tanky enemies. Dionysus can radically speed up rotations for heroes like Isis, Nemesis, or Fengyi. Demeter and Momus are easier to slot in when you are missing Nuwa but still need a frontline that stalls waves long enough for your carries to work.
B tier: playable, but outclassed
B‑tier mythics are functional. They can carry early game and plug gaps in your roster, and many bring specific utility that a top‑tier hero does not replicate exactly. The tradeoff is either lower raw numbers, awkward mechanics, or higher investment requirements.
| Character | Role | Use cases and drawbacks |
|---|---|---|
| Jormungandr | Clubs – Warrior | Opens fights with a poison field and can displace enemies, then converts damage taken just before death into a burst of true damage. Strong for chaotic brawls, but too much of his value is tied to dying. |
| Medusa | Spades – Marksman | Stacks marks that reduce magic resistance and amplify her spells, plus a cone‑shaped stun that also cuts healing; valuable magic support, but her own DPS lags until every target is marked. |
| Horus | Diamonds – Assassin | Extremely strong while in his Revenge state from his ultimate, with 100% crit rate and empowered skills; feels flat outside that window and spends downtime waiting to transform again. |
| Yanluo | Hearts – Warrior | Specializes in disruption and bossing by draining energy from attackers and scaling ultimate damage with enemy attack; outside that burst, his damage is modest. |
| Caishen | Hearts – Support | Energy battery for teammates with emergency heals through Gold Ingots and one‑time self‑save; healing dries up if Ingots are consumed too quickly. |
| Bastet | Diamonds – Assassin | Rare access to accuracy reduction for enemies and stacked dodge tools, making her surprisingly hard to kill; burst output is significantly under top assassins. |
| Diana | Clubs – Marksman | Excellent team opener that boosts energy regen, attack, and movement speed while cutting armor on the toughest enemy; her own numbers stay low unless heavily upgraded. |
| Hela | Spades – Mage | Energy‑centric mage who drains and gains energy to cycle her damaging ultimate, but mostly offers raw damage with minimal secondary utility. |
| Set | Diamonds – Warrior | Team lifesteal and attack aura, with shields and attack speed for low‑HP allies; the best parts of his kit are locked behind upgrades, making his early form unimpressive. |
| Khepri | Spades – Tank | Shield‑heavy tank with repeated knockbacks and a charging ultimate; damage is low, and his movement can unintentionally expose your backline. |
| Iris | Spades – Support | Offers stuns, silences, and a damage‑taken amplifier on her ultimate, plus reposition tools to get out of danger; suffers from long cooldowns and negligible personal DPS. |
These characters become more attractive when you are aiming at specific encounters. Medusa’s healing reduction and magic shred matter a great deal against sustain‑heavy teams. Caishen and Iris support burst comps that need faster ultimates and more control. Jormungandr and Yanluo can be slotted into boss lineups where their on‑death or attack‑scaled effects line up with mechanics.
For general progression, though, any B‑tier hero that overlaps with an S‑ or A‑tier unit is usually the one you trim once you get better pulls.
C tier: skippable mythics
C‑tier mythics are not unusable. They outperform low‑rarity heroes on raw stats and can help you smooth out early and mid‑game runs. The issue is the opportunity cost: building them requires the same scarce resources as top‑tier units without comparable payoff.
| Character | Role | Main issue |
|---|---|---|
| Ullr | Hearts – Tank | Shares damage with a backline ally and has a decent HP‑based shield, but if your formation is sound, you rarely need his panic‑button link, and his damage is low even by tank standards. |
| Surtr | Hearts – Mage | Combines crowd control and damage with a self‑shielding passive, yet is routinely outdamaged by higher‑tier mages. |
| Prometheus | Hearts – Tank | Stays resistant to knockback and gains extra reduction in a special Punishment state; that state only runs while he spends energy, so his power spikes are short and unreliable. |
| Jingwei | Hearts – Assassin | Gets stronger as allies use ultimates and can spam her own, but lacks the control or burst that define the better assassins. |
| Yuelao | Hearts – Support | Concentrates buffs and healing on two linked allies. Effective if you already have two exceptional carries; otherwise, you are trading a whole slot for marginal gains. |
| Pan | Clubs – Support | Silences, fears, and sleeps enemies, but offers very little damage and struggles to keep up when fights involve large enemy groups. |
| Sekhmet | Diamonds – Warrior | Can double her attack and force a duel against a single target; the small, fast hits that fuel her passive fall off badly against armor, and the duel damage split can be awkward for team focus. |
| Geb | Diamonds – Tank | Reflects damage based on max HP and provides solid knockbacks and mitigation, but contributes almost nothing beyond acting as an HP wall. |
If you pull one of these early, it is fine to use them at base level or with light upgrades to round out a team. The key is to stop short of deep investment once you start unlocking stronger heroes. Elevating them to the same level as S‑ or A‑tier units rarely makes sense.
Rerolling for a strong start
Progress is account‑wide and stored locally until you decide to connect to a Google account. That setup makes rerolling fairly painless if you want to chase a top‑tier opener.
Step 1: Install Immortal Codex from the Google Play Store and play through the opening sequence until you unlock your first meaningful batch of pulls and starter units.
Step 2: Check whether you landed at least one S‑tier or high‑priority A‑tier unit such as Fengyi, Freya, Athena, Zeus, Isis, Nuwa, or Nyx. If you did, you can safely commit to the account.
Step 3: If you are unhappy with the results, uninstall the game and clear the app data or cache on your device. Reinstall and repeat the process until you hit a start you like.
Whether rerolling is “worth it” comes down to patience. Starting with an S‑tier unit makes the early and mid game noticeably smoother and accelerates farming, but every mythic can clear content when leveled. If reinstalling and replaying the tutorial several times sounds tedious, it is reasonable to keep your first decent account and focus on incremental improvements.
How to use faction bonuses without hurting your team
Faction bonuses grant extra stats when you field multiple heroes from the same suit color. The temptation is to force lineups into a 4+1 or full five‑stack to chase the highest numbers on the bonus panel. In practice, that often leads to underpowered lineups that happen to share a color.
A more stable approach:
- Build the core of your team around your best units, regardless of suit.
- Once the core is set, look for a natural 3+2 split using secondary options that still fit your needs.
- Only push into heavier mono‑faction setups when you truly have strong heroes to justify it.
For example, a lineup of Fengyi, Freya, Amun‑Ra, Isis, and Nuwa may already land a 3+2 spread organically. If your only way to hit a larger faction bonus is to drop Isis for a much weaker marksman solely for color reasons, the “upgrade” on paper is usually a downgrade in combat.
Synergy between skills, ultimates, and positioning matters more than raw faction multipliers. Treat the bonus as a tiebreaker when deciding between comparable heroes, not as the primary driver of your draft.
Once you understand where each mythic roughly sits, roster decisions become much easier. Build around a small core of S‑tier heroes, pull A‑tier specialists in to plug gaps, let B‑tier units handle niche tasks or early carrying, and think carefully before going all‑in on C‑tier projects. That structure keeps your account flexible and makes each new pull easier to evaluate in terms of what it adds to your strongest five‑slot teams.
