- Build a Superhero roll odds determine which heroes you pull: Mythic sits around 0.3%–1% per roll.
- Legendary is the best value tier — roughly 2%–5% per roll with near-Mythic performance.
- Save rolls in batches and wait for rate-up banners before spending big.
- Epic heroes (8%–15%) are strong early carries — invest in one while farming more rolls.
- A well-trained Legendary can beat an under-invested Mythic.
How Roll Odds Work in Build a Superhero
Every hero in Build A Superhero comes from a gacha-style roll system. Each roll pulls from a weighted pool where higher rarities have dramatically lower drop rates but significantly stronger base stats and exclusive signature traits. Before you spend a single roll, you need to know exactly what you're rolling against.
The five rarity tiers and their approximate pull rates are:
| Rarity | Roll Chance | Stat Profile | Key Trait Value |
|---|---|---|---|
| Mythic | 0.3%–1% | 90+ base stats | Exclusive fight-turning abilities |
| Legendary | 2%–5% | High 70s to low 90s | Powerful, less game-breaking |
| Epic | 8%–15% | High 60s to low 80s | Reliable utility traits |
| Rare | 15%–20% | Above average | Basic traits |
| Common | 50%+ | Baseline ~50 stats | No unique trait |
Mythic rates swing between 0.3% and 1% depending on the active banner. Limited-time Mythic banners with boosted rates are the only smart time to chase top-tier heroes.
Hero Drop Rate Reference Table
Individual heroes inside each rarity tier carry their own weights. Here are the published per-hero roll chances for notable heroes in the pool:
| Hero | Rarity | Roll Chance | Signature Trait |
|---|---|---|---|
| Cosmic Guardian | Mythic | 0.3% | Cosmic Shield — absorbs and reflects damage |
| Speedster | Mythic | 0.5% | Time Freeze — slows enemies on hit |
| Iron Titan | Legendary | 2.5% | Titan Punch — guard-breaking charged strike |
| Shadow Phantom | Legendary | 2% | Phantom Step — teleport dash with i-frames |
| Flame Fists | Epic | 9% | Burning Blow — burn damage over time |
| Storm Caller | Epic | 8% | Chain Lightning — arcs between enemies |
| Street Vigilante | Rare | 18% | Quick Combo — fast three-hit string |
| Rookie Hero | Common | 60% | Balanced base hero for early training |
Two Mythic heroes at 0.3% and 0.5% mean most of your rolls will land Common or Rare. Plan your resource spending around the realistic outcome, not the dream pull.
Expected Rolls Per Tier: The Math
Understanding probability per roll is only half the picture — what matters in practice is how many rolls you should expect to spend before landing a target rarity.
| Target Rarity | Per-Roll Odds | Expected Rolls (Average) | ~63% Chance After |
|---|---|---|---|
| Mythic (0.5%) | 1 in 200 | 200 rolls | ~138 rolls |
| Mythic (0.3%) | 1 in 333 | 333 rolls | ~231 rolls |
| Legendary (2%) | 1 in 50 | 50 rolls | ~35 rolls |
| Epic (8%) | 1 in 12.5 | 13 rolls | ~9 rolls |
| Rare (18%) | 1 in 5.6 | 6 rolls | ~4 rolls |
These are expected values, not guarantees. A 0.5% rate means roughly 200 rolls on average for one Mythic, but variance is real — some players land one in 10 rolls, others need 500. Never gamble resources you can't afford to lose.

- Invest in Battle IQ gear
Mythic Hunter
- Batch 200+ rolls before pulling
- Only roll during boosted events
- Accept Legendary fallbacks gladly
Smart Rolling Strategy: Step-by-Step
Stockpile Free Rolls First
Redeem every active code for bonus rolls, then complete daily quests and battles that generate roll income. Batching rolls gives you more shots during rate-up windows.
Wait for Rate-Up Banners
Never roll casually on the standard banner when a limited-time Mythic banner is coming. Patience is the single biggest factor in landing a Mythic — boosted rates can triple your effective odds.
Lock a Legendary Carry
At 2%–5%, a Legendary lands within a reasonable number of rolls and can carry most content. A well-trained Legendary often beats an under-invested Mythic.
Use Epics as Farm Engines
Epic heroes like Storm Caller (Chain Lightning) clear mob waves faster than any melee Epic. One well-invested Epic farms the content that generates more rolls.
Reinvest Into Battle IQ
Once your carry is secured, shift training into Battle IQ and matching gear. High Battle IQ widens counter windows and shortens cooldowns — the real edge in PvP.
Legendary is the efficiency sweet spot: roughly 25–100x more obtainable than Mythic, with high-70s to low-90s stats that carry nearly all content when trained properly.
Roll Odds Checklist
Before your next big rolling session, run through this list:
Pre-Roll Checklist:
- All active codes redeemed for bonus rolls
- Checked whether a rate-up banner is live or upcoming
- At least 50 rolls banked before pulling (200+ for Mythic hunts)
- A Legendary carry identified as your fallback target
- Training resources reserved for the hero you actually land
| Mistake | Why It Hurts | Better Alternative |
|---|---|---|
| Rolling one at a time | Wastes rolls outside rate-ups | Batch during boosted banners |
| Over-investing in Commons/Rares | Replaced quickly by any Epic | Use as bridges only |
| Skipping Epic heroes | Slows roll farming speed | One Epic farm engine pays for itself |
| Chasing Mythic with under 50 rolls | Very low hit expectation | Bank rolls or settle for Legendary |
FAQ
Q: What are the Build a Superhero roll odds for Mythic heroes?
Mythic heroes sit at approximately 0.3% to 1% per roll depending on the active banner. Individual Mythic heroes like Cosmic Guardian (0.3%) and Speedster (0.5%) have their own separate weights within that range, so expect an average of 200-333 rolls per Mythic pull.
Q: Are Legendary heroes worth rolling for instead of Mythic?
Yes — Legendary is widely considered the best value tier. At roughly 2%-5% per roll, Legendaries land within a reasonable number of pulls and their high-70s to low-90s stats carry most content. A well-trained Legendary often beats an under-invested Mythic.
Q: Should I spend rolls on the standard banner?
Avoid it if a rate-up banner is coming. Limited-time Mythic banners with boosted rates can significantly improve your odds, so patience and batching rolls for events is the single biggest factor in landing top-tier heroes.
Q: How do I get more rolls without paying?
Redeem active codes from the in-game Codes menu, complete daily quests and battles, and use a strong Epic hero like Storm Caller to farm content quickly. Consistent farming generates a steady roll income over time.
