- Mythic robots are the top-tier pulls in Destroy a Vault and the backbone of any late-game army.
- Rolling regularly is the only way to expand your robot collection and chase higher rarities.
- Rarity beats quantity: one strong robot often outperforms several weak ones in vault attacks.
- Deployed robots earn Gold offline, so always leave your best army placed before logging out.
- Save Gems for Mutation Cores instead of routine spending once you reach boss content.
What Are Mythic Robots in Destroy a Vault?
In Destroy a Vault, robots are the core of your entire progression. You roll for robot tanks, place them into your army, and send them to blast vaults until they break open and spill Gold. Robots are divided into rarities, and the rarest tier in this gacha-style system is where players spend most of their late-game effort.
Higher-rarity robots matter for two reasons. First, they deal more damage, which means vaults break faster and you generate Gold at a higher rate. Second, a stronger army unlocks stronger vaults and Boss Vault Raids, which pay out more Gold per cycle. A mythic-tier pull effectively resets your progression ceiling.
The official loop is simple: roll rare robots, blast the vault until it breaks, smelt Gold into Cash, then upgrade your army and unlock stronger vaults. Every decision you make about robots feeds back into this cycle.
| Robot Tier | Role | Best For | Replace? |
|---|---|---|---|
| Mythic / Top Rarity | Late-game carry | Stronger vaults, Boss Vault Raids | Never — keep and upgrade |
| High Rarity | Mid-game core | Efficient standard vault farming | Only for mythic pulls |
| Mid Rarity | Early-to-mid filler | Building the first complete army | Replace as better rolls arrive |
| Low Rarity | Starter robots | First vault loop and early Gold | Replace once slots fill up |
How to Roll for Mythic Robots
Rolling is a random process, so the goal is to maximize roll frequency and never waste the results. Every robot you pull has value, either as an active army member or as a temporary placeholder while you chase better pulls.
Establish Your Gold Loop
Before chasing rare pulls, get the basic loop running: deploy your starting robots, break the current vault, collect Gold, and smelt it into Cash. Rolls and upgrades are funded by this cycle.
Fund Your Rolls
Spend early Cash on a mix of rolls and army upgrades. Rolling regularly gives you more chances at high-rarity robots, but do not roll your entire budget — keep funds for attack capacity upgrades.
Compare New Pulls to Your Army
After every roll session, compare new robots against your active lineup. Swap in any robot with higher rarity or better damage, and move replaced robots out of your attack slots.
Expand Placement Slots
More slots mean more robots attacking at once. When your roster has more useful robots than your slots allow, expanding placement capacity is one of the highest-value upgrades.
Keep Your Best Army Deployed
Deployed robots keep earning Gold while you are offline. Always log out with your strongest lineup placed so idle income funds your next round of rolls.
Do not keep low-rarity robots in active slots just because they were expensive to upgrade. Once a higher-rarity pull is ready, replace them — a weak slot slows every vault attack and every offline earning cycle.
Mythic Robot Army Setup by Game Stage
The best army setup changes as you progress. Early on, filling every slot matters more than perfect rarity. Later, only your strongest robots belong in the active army.
Early Game Setup
- Priority: fill every slot
- Use any robot you roll
- Focus Cash on basic upgrades
- Break starting vaults for Gold
Mid Game Setup
- Priority: high-rarity core
- Replace weakest robots first
- Expand attack slots
- Push into stronger vaults
Late Game Setup
- Priority: mythic-focused army
- Maximum rarity lineup
- Save Gems for Mutation Cores
- Target Boss Vault Raids
| Stage | Army Focus | Vault Target | Gem Spending |
|---|---|---|---|
| Early | Full slots, any rarity | Standard vaults | Sit on Gems early |
| Mid | High-rarity core | Stronger vaults | Optional premium picks |
| Late | Mythic-heavy lineup | Boss Vault Raids | Mutation Cores |
The BOSSES update added Boss Vault Raids and Mutation Cores. Use Mutation Cores only on robots expected to stay in your long-term army, and build a high-damage lineup before committing to boss content.
Turning Mythic Robots into Gold and Cash
A mythic robot is only as valuable as the income it generates. The resource chain in Destroy a Vault flows from vault attacks into Gold, from Gold into Cash, and from Cash into permanent upgrades.
| Resource | Source | Conversion | Best Use |
|---|---|---|---|
| Gold | Breaking vaults, offline robot earnings | Smelt into Cash | Fuels the entire loop |
| Cash | Smelting Gold | Primary spending currency | Army upgrades, base expansion |
| Gems | Codes, premium sources | Buy Mutation Cores | Mutation progression |
| Mutation Cores | Purchased with Gems | Robot mutation upgrades | Long-term army robots |
Two habits multiply your income. First, always attack the strongest vault your army can defeat efficiently rather than farming an easy target long after you have outgrown it. Second, collect offline earnings every time you log in, smelt that Gold immediately, and put the Cash back into slots or robot upgrades.
Attack the highest vault you can break at a steady pace. A vault that is slightly too strong wastes time; a vault that is far too weak wastes your army's potential.

FAQ
Q: How do I get mythic robots in Destroy a Vault?
Mythic-tier robots come from the roll system. Roll regularly, fund rolls through the Gold-to-Cash loop, and compare every new pull against your active army so stronger robots replace weaker ones immediately.
Q: Do mythic robots earn Gold while I am offline?
Yes. Deployed robots continue generating Gold automatically while you are offline. Always leave your strongest army in place before logging out, and collect the accumulated Gold when you return.
Q: What are Mutation Cores and should I buy them?
Mutation Cores were added in the BOSSES update and are purchased with Gems. They are a premium progression path, so save Gems and spend Cores only on robots that will remain in your long-term attack army.
Q: Should I replace a low-rarity robot I already upgraded?
In most cases, yes. A higher-rarity robot in an active slot improves every vault attack and every offline earning cycle, which quickly makes back the resources you invested in the older robot.
