Traits & rarity explained
Every Bungo you own has 12 traits, each locked in at creation, each rolled at one of five rarity tiers. Those traits drive Power Score, flavor breeding odds, and determine how your roster looks on the leaderboard. Here's how all of that actually fits together.
The 12 trait slots
Traits cover every visible dimension of a Bungo: body color, body shape, eye style, mouth, markings, accent patterns, and others. Each slot rolls independently when the Bungo is first spawned (or bred). Once set, traits never change — leveling, ascension, and gear don't touch them. What you hatch is what you get.
A few trait slots have rare one-off variants — pattern glitches, seasonal colorways, or multi-rarity mixes. These are functionally Legendary but add cosmetic distinction beyond the five-star tier ceiling.
The 5 rarity tiers
Power Score — what actually moves it
Each Bungo has one Power Score that aggregates rarity across all 12 trait slots. A Bungo with mostly Common traits and one Legendary sits far below a Bungo with 12 Rare traits, even though Legendaries feel rarer. The math favors breadth: uniformly decent beats unevenly spectacular.
Ascension level, gear tier bonuses, and prestige cosmetics also contribute, but raw trait rarity is the dominant factor early on. Once your gear is tier-5 across the board, further progress comes almost entirely from trait upgrades via breeding.
How breeding skews the odds
Bred offspring inherit traits from both parents with a weighted roll favoring the rarer parent. If parent A has a Legendary eye and parent B has a Common eye, the child rolls heavily toward Legendary. There's still variance — you won't always get the rarer side — but the skew is real.
Two consequences:
- Your best Bungos should be your breeding stock. Don't retire a Bungo with multiple Epic traits unless you've already bred it or cloned the good traits into a child.
- One-sided pairings outperform balanced pairings. If you want a specific rare eye, breed your rare-eye Bungo with any other Bungo — don't wait until both parents have good eyes. The weighted roll does the work.
Perk points and the odds shift
When you retire a Bungo, it converts into perk points. Perk points can be spent to increase the roll weight toward rarer tiers on a single breeding attempt. Think of them as a thumb on the scale — not a guarantee, but a real nudge.
The optimal use of perk points is late-project, when you've already bred a solid near-complete Bungo and you're trying to push one or two specific slots over the line. Early-project, perk points are less efficient than just breeding more.
One more thing: gear tiers
Don't forget that gear tier bonuses also count toward Power Score and are fully under your control. A modestly-trait-rare Bungo with tier-5 gear across the board will outscore an untiered Bungo with stronger traits, at least until late game. If your leaderboard rank matters more than the aesthetics of a perfect Legendary Bungo, maxing gear is the faster path.
