🐉 How Traits Are Earned During Incubation: Brilliance Is Everything
Every time an egg "mutates for the better" during incubation, the game doesn't just hand you a trait outright: it lets you choose 1 out of 3. What determines the quality of those 3 options is the egg's Brilliance. The better you incubate it (more turns and better bonuses), the more Brilliance rises... and the better traits start showing up.
Let's break it down.
The 5 "trait pools"
Every trait belongs to a rarity. From worst to best:
🟢 Common → 🔵 Uncommon → 🟣 Rare → 🟠 Epic → 🔴 Unique
On each roll, the game first decides which pool you're drawing from, based on your Brilliance, and then shows you 3 traits from that pool so you can choose one.
The golden rule
The more Brilliance you have, the more often you get a good pool.
It's not that high Brilliance makes Commons disappear; it's that the balance shifts toward Rare, Epic, and Unique. Here is the real probability table, showing the chance of landing in each pool:
Brilliance 🟢 Common 🔵 Uncommon 🟣 Rare 🟠 Epic 🔴 Unique
10 100% - - - -
30 55% 30% 15% - -
50 30% 40% 25% 5% -
70 18% 36% 33% 13% -
90 11% 26% 38% 24% 1%
110 5% 15% 39% 38% 3%
130 1% 5% 25% 64% 5%
Brilliance works in brackets of 10: a Brilliance of 47 uses the 40 row, a Brilliance of 112 uses the 110 row, and so on.
Two rules you really need to understand
1️⃣ If it says 0%, it really is 0%.
With Brilliance 30, you will never see an Epic or a Unique in a normal roll. That isn't bad luck, it's impossible. You need to raise Brilliance to "unlock" those pools. At 10, only Commons can appear.
2️⃣ You will never run out of offers - but the game will never move you up a pool.
If the roll lands on the Rare pool but you already own every Rare, the game drops to the next lower pool, Uncommon, and if needed to Common, until it finds traits you still don't have. What it will never do is move upward: a Rare roll will never give you an Epic "for free." The floor is Common, and the ceiling is the pool you rolled.
📋 Example 1 - "not-so-bright" egg (Brilliance 30)
Three rolls in a row might look like this:
Roll 1 → Common pool: choose between Brave / Swift / Agile
Roll 2 → Uncommon pool: choose between Fire Resistant / Regenerate / Reflex
Roll 3 → Rare pool (you got lucky, 15%): choose between Bloodlust / Hypnotic / Fire Shield
Epics and Uniques? Not a single one, no matter how hard you try. This egg needs more incubation.
📋 Example 2 - "genius" egg (Brilliance 110)
Roll 1 → Epic pool (38%): choose between Powerful Breath / Colossal / Life Drainer
Roll 2 → Rare pool (39%): choose between Magic Claws / Bloodlust / Phoenix Reborn
Roll 3 → Unique pool (3%!): choose between Chameleonic / Ethereal / Immortal
Here, Commons barely show up, and every now and then you hit the jackpot.
💡 Fun fact: with Brilliance 110, if you incubate enough (≈1000 test mutations), it is practically guaranteed that you will see at least one Unique pool. At a 3% chance per roll, not seeing one would be a statistical miracle.
⚡ Upgrading: traits from the same family
This is the juiciest mechanic in the system, and also the one that causes the most confusion. Some traits form chains within the same category. The headline example is:
Size: 🟢 Large → 🔵 Huge → 🟠 Colossal
The 3 rules of trait chains
1️⃣ You only keep the highest step.
You do not stack Large Huge Colossal. Your dragon simply has the highest level reached in that category. The chain represents a single trait that keeps improving.
2️⃣ A duplicate is NOT wasted: it upgrades you by one step.
If you already have Large and the roll offers another Size trait, the game does not give you a useless second Large. It offers the next step above your current best. If you have Large, you get Huge. If you have Huge, you get Colossal.
3️⃣ Once you reach the top, that category is completed and stops appearing.
Once you have Colossal, the Size category disappears from your offers, because there is nothing left to improve there.
The chains that currently exist
Category Chain (lowest to highest)
Size Large → Huge → Colossal
Life drain Hungry Touch → Bloodlust → Life Drainer
Jumps / Teleportation Reflex → Ghostly Illusions → Blink
Physical damage resistance Astral → Spectral → Ethereal
Magical evasion Shadowy → Blurred Silhouette → Ghostly
Alchemy Affinity Lesser → Standard → Greater
Bureaucrat Bureaucrat → Expert Bureaucrat → Finance Wizard
Fear Auras Aura of Fear → Aura of Terror
Fame Famous → Legendary Fame
Strategist Strategist → Great Strategist
Arcane Wisdom Explorer → Sage of the Arcane
I'm the Alpha Defiant → Tyrant King
🌟 The master trick: chains cross rarity tiers
Look at the steps in this chain:
Physical damage resistance: Astral (🔵 Uncommon) → Spectral (🟠 Epic) → Ethereal (🔴 Unique)
This has huge strategic implications:
You can reach a UNIQUE trait without ever rolling the Unique pool.
If your dragon picks up Astral early on, which is only Uncommon and fairly easy to find, then every time that category comes up again, it will keep climbing: Astral → Spectral → Ethereal. You reached a Unique by upgrading, not by jackpot luck.
The same happens with Size (Large Common → Colossal Epic) or Life Drain (Hungry Touch Uncommon → Life Drainer Epic).
⚠️ Important for sharp-eyed players: this is why you will sometimes see a trait appear that is of a higher rarity than your Brilliance "should" allow. That is not a bug. It is the upgrade system pushing a chain you had already started. The 0% rule only applies to the initial roll for each pool; upgrading is the legitimate way to bypass that ceiling.
🎯 In short (TL;DR)
Incubate more → raise Brilliance → get better pools. There are no shortcuts to Epics and Uniques except raising Brilliance... or upgrading chains.
With low Brilliance, higher rarities are impossible. 0% really means 0%.
You will never run out of choices: if a pool is exhausted, the game drops to lower ones. It never moves up.
Chains do not stack, they scale. A duplicate moves you one step up; once you hit the top, that category is complete.
Starting a chain early is gold. It is the only way to reach Epic or Unique traits with modest Brilliance. If you get Astral or Large early, chase them hard.
