The Trait Machine is one of the most impactful buildings you can buy in Catch and Tame, the Roblox tycoon simulator developed by Manta Games. It lets you roll — and re-roll — passive abilities on your pets, potentially turning a solid Legendary into something that dominates dungeons and PvP. It's also one of the most expensive systems in the game, so knowing what to aim for and what to skip will save you thousands of Gems.
Quick answer: The Trait Machine costs 1,000,000 Coins from the shop's building section. Place it on your farm, select a pet, and spend either 500 Coins (Standard Reroll) or 50 Gems (Premium Reroll) per spin to assign a random trait. Never use it on pets below Epic rarity — save your currency for Legendary and Mythical pets.
Unlocking and Placing the Trait Machine
You won't have access to the Trait Machine right away. It sits behind a 1,000,000-Coin price tag in the shop, under the Buildings tab. For new players, that means catching animals with your starter Lasso, filling your pen, and steadily upgrading both your Lasso and your farm's capacity until you've banked enough passive income. Prioritize expanding your base early so more pets can generate money simultaneously.
Once purchased, place the Trait Machine anywhere on your farm. Walk up to it and interact to open the re-roll menu. On some regional servers, the building may appear labeled as "Magic Lab" — it's the same machine with the same functionality.
If you're working toward the Trait Machine from scratch, the fastest path is straightforward: catch everything you can, place every animal in your pen, spend early earnings on Lasso upgrades, and expand your fence. Duplicate pets are fine — even identical species can generate different income amounts, so quantity matters.
Re-roll Costs: Coins vs. Gems
Every spin of the Trait Machine assigns a random trait to the selected pet, replacing whatever trait it had before. Two currency options are available, and they differ in more than just price.
| Reroll Type | Currency | Cost per Spin | Luck Bonus |
|---|---|---|---|
| Standard Reroll | Coins | 500 | None |
| Premium Reroll | Gems 💎 | 50 | +25% chance for S-Tier or A-Tier traits |
The Premium Reroll's 25% luck bonus makes a meaningful difference when you're chasing the rarest traits. But at 50 Gems per spin, costs add up fast. Hitting a Godly (S-Tier) trait takes roughly 1,000 re-rolls on average — that's about 50,000 Gems or 500,000 Coins. A Legendary (A-Tier) trait is more realistic at around 100 Premium Rerolls, or approximately 5,000 Gems.
Trait Tier List: S-Tier Through D-Tier
Not every trait outcome is equal. Some traits dramatically boost your pet's combat or farming output, while others actively make your pet worse. Here's how the trait pool breaks down.
Godly Traits (S-Tier) — 0.1% Drop Rate
| Trait | Effect | Best Use Case |
|---|---|---|
| Ethereal | +50% Damage | The strongest offensive trait in the game. Turns high-base-damage pets into boss-killing machines. |
| Vampire | Life Steal (heals 20% of damage dealt) | Ideal for solo dungeon runs and sustained PvP fights. |
Legendary Traits (A-Tier) — 1% Drop Rate
| Trait | Effect | Best Use Case |
|---|---|---|
| Berserker | +30% Attack, −10% Defense | Glass cannon DPS builds |
| Giant | +25% HP, +15% Defense | Tank pets for Spire runs and raids |
Traits to Avoid (D-Tier) — 30–50% Drop Rate
| Trait | Effect | Why It's Bad |
|---|---|---|
| Lazy | −10% Speed | Slows your pet down with no upside. Instant re-roll. |
| Weak | −15% Attack | The worst offensive penalty in the trait pool. |
| Fragile | −20% Defense | Pets die far too quickly in any combat scenario. |
If you land any D-Tier trait, re-roll immediately. These traits actively hurt your pet's performance and have no niche use.
The Ride Trait
One of the most sought-after outcomes from the Trait Machine is the Ride trait. When a pet receives it, you can mount and ride that animal across the map, moving significantly faster and improving your ability to chase down rarer creatures. To use it, leave your farm with your pet, and Lasso equipped — a ride button will appear on screen.
The Ride trait doesn't always show up on the first spin. It competes with every other trait in the pool, so you may need several re-rolls before it appears. That said, even if you don't land Ride right away, other useful traits — ones that boost income generation or speed up leveling — are still worthwhile outcomes in the meantime.
Which Pets Deserve Trait Machine Investment
Gems and Coins are limited resources. Spending them on the wrong pet is one of the most common mistakes players make. Follow this priority order to get the most value from the Trait Machine.
Priority 1: Mythical Pets
Always use Premium Rerolls on Mythical pets. These are your end-game carries. The Void Dragon, for example, has the highest base damage in the game — pairing it with the Ethereal trait pushes its total DPS to roughly 375 (250 base × 1.5). Budget between 5,000 and 10,000 Gems per Mythical pet and aim exclusively for Ethereal or Vampire.
Priority 2: Legendary Pets
Use Premium Rerolls only on your primary DPS Legendary, such as the Magma Dragon or Void Dragon. For utility Legendaries like the Golden Lion, Standard Rerolls (Coins) are fine. The Magma Dragon pairs exceptionally well with the Vampire trait, letting it solo dungeons without a healer. The Golden Lion benefits most from Giant, amplifying its team buff ability through higher HP.
Priority 3: Epic Pets (Conditional)
Only re-roll Epic pets if you have a large surplus of Coins. Stick to Standard Rerolls and stop as soon as you land any A-Tier or B-Tier trait. Never spend Gems on Epics.
Expected Gem Costs at Each Tier
| Target Trait Tier | Drop Rate | Avg. Rerolls Needed | Estimated Gem Cost |
|---|---|---|---|
| Godly (S-Tier) | 0.1% | ~1,000 | ~50,000 Gems |
| Legendary (A-Tier) | 1% | ~100 | ~5,000 Gems |
| A-Tier or better | 5% | ~20 | ~1,000 Gems |
These numbers assume Premium Rerolls at 50 Gems each. Standard Rerolls using Coins will have slightly worse odds for top-tier traits due to the absence of the 25% luck bonus.
Other Buildings That Complement the Trait Machine
The Trait Machine doesn't exist in a vacuum. Several other purchasable buildings accelerate your overall progression and feed into a stronger trait-rolling strategy by helping you acquire better pets faster.
| Building | Effect |
|---|---|
| Nursery | Eggs hatch 20% faster |
| Legendary Nursery | Eggs hatch 50% faster with 10% more luck |
| Cosmic Nursery | Eggs hatch 100% faster with 20% more luck and 10% mutation luck |
| Farm House | Additional pet storage |
| Animal Post | Keeps animals attached in place |
Breeding two pets produces an egg that can hatch into rarer animals, and placing those eggs in an upgraded Nursery dramatically improves your odds of getting Legendary or Mythical pets worth investing Trait Machine rolls on. Tap the heart icon at the bottom of your screen to breed, and check the Recipes menu on the left side to discover optimal breeding pairs.
The Trait Machine is the single most powerful min-max tool available in Catch and Tame once you reach the mid-to-late game. The key is patience and discipline — resist the urge to burn Gems on anything below Legendary rarity, target the right trait for each pet's role, and accept that RNG will sometimes be unkind. When it does cooperate, though, a well-traited Mythical pet can carry you through every piece of content the game offers.
