Unit roster and summon odds

Five rarity bands — the percentages shown on the summon panel. Evolved forms don't drop; they're crafted (see below).

UnitRarityPull oddsNotes

Read the odds right: two-thirds of pulls are Rare, a quarter Epic. Legendary ~1 in 22, Mythic ~1 in 200, Secret ~1 in 2,000 — build your team around Jake and Marceline first, and treat Secrets as long-term luck.

Evolutions

Evolving happens at the Enchiridion in the lobby. The recipe for every hero: 10 of their material + 5 Enchiridion Pages + 1,000 Gems. Materials drop one per win from that hero's Act 5 stage; evolution keeps your level, XP and trait.

Farming math: 10 materials at one per win = 10 clears of that Act 5, plus the Gems. Each clear also pays 50 Gems on replay, so the run partly funds itself. Materials also drop from Dungeon Train challenges, and the premium battle pass includes two of every item.

Traits

One passive trait per unit. Reroll at Castle Lemongrab for 1 Trait Crystal per roll; the 11 outcomes and odds below are from the in-game panel.

Lobby systems

The Enchiridion — evolution

The "book of heroes" in the lobby: add a hero, feed it 10 of its material plus 5 Pages and 1,000 Gems, and it evolves into its Mythic form keeping level, XP and trait.

Castle Lemongrab — trait reroll

Far left of the hub. One Trait Crystal rerolls a hero's passive trait; the VIP game pass (349 Robux) improves the odds here and gives 20% off summons.

Jake's Code Corner — codes

In the Tree Fort. This is where codes redeem for free Gems, Trait Crystals and Units of Juice.

Dungeon Train — challenges

Challenge mode that drops evolution materials alongside campaign farming.

Progression worlds

Campaign Acts run through themed kingdoms — Candy Kingdom, Ice Kingdom, Fire Kingdom, MO Factory, Castle Lemongrab, Nightosphere and Crystal Dimension each end in an Act 5 stage that drops that hero's evolution material.

FAQ

Do I lose level or trait when evolving?

No — evolution carries over level, XP and the assigned trait. Roll a good trait on the base hero before evolving, and it stays on the Mythic form.

What do Trait Crystals and Units of Juice do?

Trait Crystals reroll traits at Castle Lemongrab (1 per roll). Units of Juice feed stat/level progression. Both drop from matches, quests, codes and the battle pass.

Are the paid passes worth it?

The 2x Drops pass (599 Robux) doubles evolution-item and crystal payouts — the real time-saver. The Premium Battle Pass (799 Robux) bundles two of every evolution item. Neither is required; everything is farmable.

How many units can I place?

Six heroes in your squad; some evolved forms have placement limits — King BMO caps at 2 on the field.
