Summon rates
| Rarity | Chance per summon | Units seen in the pool |
|---|---|---|
| Secret | 0.05% | Magic Man (shown as “???” on the rate screen) |
| Mythic | 0.5% | Princess Bubblegum, Lemongrab, Billy |
| Legendary | 4.5% | Marceline |
| Epic | 24.99% | Lady Rainicorn, Flame Princess, BMO |
| Rare | 69.96% | Finn, Jake |
These rates come from the in-game “All Rates” screen as transcribed by one careful fan wiki, so treat them as ⚠️ single-source until the developer publishes them. The pool above is from one snapshot — the featured Mythic rotates.
- Featured unit: the banner’s featured hero takes 75% of Mythic pulls — about 0.375% per summon for that exact hero.
- Pity: a Legendary or better is guaranteed within 50 summons. No Mythic pity is known.
- Free summon: the button sometimes shows “1 free!”. How often isn’t documented.
How many gems do you need?
Use the calculator above. Some handy numbers at the base rates (10× summons, no passes):
| Goal | 50% chance | 90% chance |
|---|---|---|
| Any Mythic (0.5%) | 139 summons ≈ 6,300 gems | 460 summons ≈ 20,700 gems |
| Any Mythic with Lucky Summons (1%) | 69 summons ≈ 3,150 gems | 230 summons ≈ 10,350 gems |
| The featured Mythic (0.375%) | 185 summons ≈ 8,350 gems | 613 summons ≈ 27,600 gems |
| A Secret (0.05%) | 1,386 summons ≈ 62,400 gems | 4,605 summons ≈ 207,250 gems |
On average a Mythic costs 200 summons (about 9,000 gems). For comparison, all codes together give 4,600 gems and each 7-day login streak gives 7,000.
Passes that change summoning
| Pass | Price | Effect |
|---|---|---|
| Lucky Summons | 399 Robux | Mythic ×2, Legendary ×1.5 on every summon |
| VIP | 349 Robux | Summons 20% cheaper (40 gems, 360 for 10) plus better trait odds |
Both are official pass descriptions. More in are the gamepasses worth it.
Who should you summon for?
Mythics like Lemongrab and Princess Bubblegum have evolutions (Lemongrab 3, Candy Elemental Bubblegum) and sit at the top of most tier lists. Check which Mythic is featured before you spend — you can see the banner timer at the Treasure Hoard.
