If you’re diving into Siberium right now, you’re stepping into an idle RPG where your early pulls can either smooth out the entire midgame… or leave you grinding harder than you need to. The good news: the current meta is surprisingly readable, and faction bonuses make team-building more structured than the usual “jam your rares together and pray” gacha chaos.
Below is a March 2026 Siberium tier list that ranks the best heroes across all factions, plus a reroll guide that cuts through the usual misinformation. If you want the short version: build toward a single faction bonus early, prioritize S-tier staples for late-game bosses and events, and don’t waste hours rerolling unless you’re dead-set on a specific start.
What We Know: How Factions (and Bonuses) Actually Shape the Meta
Siberium splits its roster into five factions, and the game heavily encourages you to commit—at least at first—because of the faction bonus system. Field five heroes from the same faction and you activate a powerful stat package that can dramatically accelerate progress.
The factions are:
- Temple (Blue)
- Divine Realm (Yellow)
- Demon (Red)
- Undead (Cyan)
- Chaos (Purple)
There’s also a faction strength/weakness relationship described as a rock-paper-scissors style chart:
- Yellow <> Purple
- Blue > Cyan > Red > Blue
That matters because even if a hero is individually cracked, you’ll still feel it when you’re pushing content into a faction that naturally resists your team’s damage profile or pressure.
Why “One Faction First” Is the Correct Early-Game Play
Early on, you can absolutely run a mixed squad with whatever the gacha hands you—especially since you’ll be pulling a lot. But the smart path is to pick a faction lane and invest your upgrades there until you can consistently trigger the 5-hero bonus.
A concrete example given for Chaos shows how meaningful these bonuses can be: deploying five Chaos heroes can activate HP +30%, ATK +22%, and DMG Inc. +5%. That’s not a “nice-to-have.” That’s a “your account now progresses faster” switch.
Later, the long-term plan shifts: once you’re approaching endgame, the idea is to build multiple teams, potentially one per faction, so you can rotate into favorable matchups and handle different bosses/events more efficiently.
Siberium Tier List (March 2026): Best Heroes Ranked by Faction
This tier list is structured by faction because that’s how you’ll actually build teams in Siberium. The heroes listed in S tier are positioned as the go-to picks thanks to their highest stats and best skills, making them the safest investments for late-game stages, bosses, and events.
Demon (Red) — Best Heroes
S Tier (Demon)
- Blade Master
- Slayer
- Gabur
- Queen of Pain
A Tier (Demon)
- Moon
- Lord of Terror
- Illidan
B Tier (Demon)
- Devil Warrior
- Kratos
C Tier (Demon)
- Big Mouth
- Evil Flame
- Minotaur
My take: Demon’s top end is clean and focused—four S-tier targets that give you a clear “if you pull this, build it” signal. If you’re trying to brute-force progression and you land Blade Master or Queen of Pain, you’re in business.
Temple (Blue) — Best Heroes
S Tier (Temple)
- Bam the Great
- Li
- Voland
- Sandra
A Tier (Temple)
- Mechanic
- Judge
- Paladin
- Adventurer
B Tier (Temple)
- Tiki
- Ace
- Sword Lady
C Tier (Temple)
- Alice
- Guardian of Time
- Andis
My take: Temple looks like the faction for players who want a deep bench. Even outside S tier, Temple’s A-tier list is stacked with names you can slot in without feeling like you’re sabotaging your own account.
Undead (Cyan) — Best Heroes
S Tier (Undead)
- Oliver
- Veela
- Aida
- Devil Hand
- Wolf
- Fergus
- Medusa
A Tier (Undead)
- Captain
B Tier (Undead)
- Rock
- Phantom
C Tier (Undead)
- Shadow Priest
- Blood Nun
- Ghost Warrior
My take: Undead has the most crowded S tier of the bunch, which is a huge deal for consistency. If you’re leaning Undead, you’re statistically more likely to stumble into an S-tier cornerstone simply because there are more of them.
Divine Realm (Yellow) — Best Heroes
S Tier (Divine Realm)
- Altair
- Sword God Lee
- Thor
- Mercy
- Visa
A Tier (Divine Realm)
- Ice Emperor Ivan
- Kirk
- Sword of Destiny
- Archangel
- Lodd
B Tier (Divine Realm)
- Rage
- Seraph
- Ral
- Mindcatcher
C Tier (Divine Realm)
- Disciple
- Prophet
- Holy Spirit Warrior
My take: Divine Realm reads like a “premium” faction: a tight S tier with big-name energy (yes, Thor is here), plus a very respectable A tier. If you’re trying to build a faction team that doesn’t need a million substitutions, Yellow looks stable.
Chaos (Purple) — Best Heroes
S Tier (Chaos)
- Long
- Minos
- Lucifer
- Hades
- Lai
- Valkyrie
- Emperor
A Tier (Chaos)
- King Button
- Alexia
- Kaas
B Tier (Chaos)
- James
- Wayne
- Sly
- Traitor
C Tier (Chaos)
- Chaos Ghost
- Sivir
- Bear Warrior
My take: Chaos is exactly what you want from a faction in an idle RPG: a loaded S tier and a faction bonus example that screams “build me.” If you’re starting fresh and you pull Lucifer, Hades, or Valkyrie, Chaos is an easy commitment.
Cross-Faction “Best of the Best”: Who You Should Be Happiest to Pull
Because the tier list is faction-split, the cleanest way to answer “who are the best ones across all factions?” is to look at every S-tier hero as the current top shelf.
Here are the S-tier heroes across all factions (March 2026):
- Demon: Blade Master, Slayer, Gabur, Queen of Pain
- Temple: Bam the Great, Li, Voland, Sandra
- Undead: Oliver, Veela, Aida, Devil Hand, Wolf, Fergus, Medusa
- Divine Realm: Altair, Sword God Lee, Thor, Mercy, Visa
- Chaos: Long, Minos, Lucifer, Hades, Lai, Valkyrie, Emperor
If you’re reroll-obsessed (we’ll get to why you probably shouldn’t be), these are the names you’re chasing.
Reroll Guide (March 2026): Should You Reroll in Siberium?
Here’s the blunt truth: rerolling in Siberium is not mandatory, and it’s even described as pointless given how the game’s early systems are structured.
Two key reasons are called out:
- The advanced gacha guarantees you at least one SS rarity hero.
- You get a ton of summoning tickets through codes and missions, meaning your roster fills out quickly without needing to reset your account repeatedly.
In other words: the game is already designed to flood you with pulls. The opportunity cost of rerolling—time spent repeating the opening—often isn’t worth what you gain.
How to Reroll Anyway (Fast Method)
If you still want to reroll, Siberium’s reroll method is server-based:
- Log in to the game and do your summons.
- If you don’t like the results, return to the login screen.
- Select a different server.
- Start over.
That’s it. No complicated account deletion steps are required in this approach—just a server swap.
How to Use This Tier List Without Bricking Your Progress
Tier lists are only useful if they translate into decisions. Here’s how I’d apply this one in real play, using only what’s been established about Siberium’s systems:
1) Early Game: Prioritize Faction Completion Over Perfect Units
Because the 5-hero faction bonus is such a big lever, your first goal isn’t “build five S-tier units.” It’s “build five units from one faction that I can upgrade efficiently.”
If you already have an S-tier hero in a faction, that’s your sign to lean into it.
2) Midgame: Replace the Weak Links With S/A Tier
Once your faction core is online, start swapping out lower-tier pieces for S-tier and A-tier heroes within that same faction. This keeps your bonus active while raising your ceiling.
3) Endgame: Expand Into Multiple Faction Teams
The guidance is clear: later on, you can aim to build multiple teams, potentially one per faction. That’s where the faction matchup chart becomes more relevant, and where having depth across the roster stops being a luxury and becomes a necessity.
What Remains Unknown
A few details that would normally matter for a full meta breakdown have not yet been confirmed in the available information:
- Platform availability (mobile/PC) and storefront specifics have not been stated here.
- Developer/publisher details for Siberium have not been specified.
- Exact definitions of rarity tiers (including what “SS rarity” entails numerically) aren’t explained.
- No official breakdown is provided for why each S-tier hero is top-tier (skills, roles, scaling, etc.), beyond the general note that they have the best stats and skills.
If those specifics get clarified in official materials or patch notes, they’ll change how confidently we can recommend certain heroes for specific modes (bossing vs events vs progression).
If you want, tell me which faction you’re currently leaning toward (or which S/SS hero you pulled), and I’ll help you map a clean “five-hero faction bonus” path using the tiers above—no wasted upgrades, no dead-end investments.
