- Destroy a Vault ranks robots by rarity from Common up to Mythic-quality pulls.
- Core loop: roll robot tanks, blast vaults for Gold, smelt Gold into Cash, upgrade.
- Early game: a full active army beats chasing rare pulls you cannot deploy.
- Late game: reserve Gems for Mutation Cores and Boss Vault Raid readiness.
- Offline earnings: deployed robots keep generating Gold while you are away.
Destroy a Vault Common to Mythic Tier Rankings
Robot tanks in Destroy a Vault are obtained through random rolls and organized by rarity. Higher rarities deliver stronger damage against vaults and better Gold efficiency, but rarity alone does not decide your build — deployment slots, army composition, and upgrade investment all matter. This ranking walks through each tier from the baseline robots you start with to the top pulls worth long-term investment.
| Tier | Rarity Focus | Stage | Damage Value | Keep or Replace |
|---|---|---|---|---|
| S Tier | Highest available rarities (Mythic-tier pulls) | Late Game | Best overall damage | Keep and upgrade whenever they fit your active army |
| A Tier | High-rarity robots | Mid Game | Strong damage for regular vault attacks | Keep until a higher-rarity replacement is ready |
| B Tier | Common and lower-rarity robots | Early Game | Useful starting damage | Keep active until stronger rolls arrive |
| C Tier | Low-value duplicates | Replacement Tier | Lower contribution vs stronger vaults | Replace gradually without weakening the active army |
Common Tier
- Baseline damage
- Fills early army slots
- Immediate vault access
- Replace when better pulls land
Uncommon to Rare
- Noticeable damage jump
- Reliable mid-early workhorses
- Good offline Gold generators
- Solid until stronger vaults unlock
Epic Tier
- Strong vault-breaking power
- Mid-game army core
- Efficient Gold per attack
- Worth early upgrade investment
Mythic Tier
- Top damage potential
- Boss Vault Raid candidates
- Best long-term investment
- Pair with Mutation Cores
A full army of mid-rarity robots deployed across every available slot usually outperforms a half-empty lineup with one strong pull. Prioritize army completion first, then chase higher rarities.
How Rare Robots Are Obtained
Rolling is the main acquisition system. Each roll produces a robot tank at random rarity, which means progression is a mix of resource management and luck. Gems, earned through premium sources or redeem codes, support specialized progression such as Mutation Cores from the BOSSES update.
Accumulate Roll Resources
Attack vaults, collect Gold, and smelt it into Cash so you can keep rolling for new robot tanks.
Roll and Compare
Roll regularly and compare each new robot against your current active army before deciding to slot it in.
Deploy Into Placement Slots
Place your best robots into available slots. Slot capacity limits how many robots attack at once.
Upgrade and Mutate
Spend Cash on army upgrades, then use Gems for Mutation Cores on robots that will stay in your long-term lineup.
Prepare for Boss Vault Raids
Build toward a high-damage army with your strongest, most upgraded robots before committing to Boss Vault Raids.
| Resource | Source | Primary Use |
|---|---|---|
| Gold | Breaking vaults, offline robot earnings | Smelt into Cash |
| Cash | Smelting Gold | Army upgrades, base expansion, attack slots |
| Gems | Premium sources, redeem codes | Mutation Cores and special progression |
| Mutation Cores | Purchased with Gems | Mutation-related robot progression |
Do not burn Gems on routine army spending. Save them for high-value purchases such as Mutation Cores, which support the robots you plan to keep permanently.
Vault Difficulty and Recommended Robot Setup
Each vault tier demands a different army standard. Match your robot quality to the target vault so every attack cycle stays efficient instead of stalling against overwhelming durability.
| Vault Level | Durability | Recommended Setup | Best For |
|---|---|---|---|
| Standard Vaults | Baseline | Fill every placement slot with your strongest available robots | Early progression and roll funding |
| Stronger Vaults | Higher than baseline | Prioritize high-rarity robots, upgrades, and extra slots | Efficient farm once your army clears them quickly |
| Boss Vault Raids | Boss-level durability | Highest-rarity, fully upgraded robots at maximum deployment | Advanced progression and high-value attacks |
Attack the strongest vault your army can break efficiently. Stalling on a vault that is too tough wastes attack time that could be generating Gold elsewhere.
Milestone Checklist: From Common Start to Mythic Army
Work through these milestones in order. Each one unlocks the next stage of the rarity ladder and keeps your Gold-to-Cash loop scaling.
Common to Mythic Milestones:
- Fill every placement slot with any available robots
- Establish the Gold-to-Cash smelting loop
- Replace Common robots with Rare or better pulls
- Upgrade attack slots and base capacity
- Build an Epic-or-better core army for stronger vaults
- Save Gems for Mutation Cores on top pulls
- Prepare a max-deployment army for Boss Vault Raids
Keep your best robots deployed before logging off. Deployed robots continue earning Gold automatically, funding your next round of rolls and upgrades while you are away.
FAQ
Q: Are Mythic robots required to progress in Destroy a Vault?
No. A complete army of mid-rarity robots deployed across all slots handles standard and stronger vaults well. Mythic pulls become important mainly for Boss Vault Raids and late-game efficiency.
Q: Should I replace Common robots immediately after a better roll?
Only replace them when the new robot fits an open slot or clearly outperforms the current member. Never leave slots empty waiting for a rare pull.
Q: What are Mutation Cores and which robots should get them?
Mutation Cores are purchased with Gems and introduced with the BOSSES update. Apply them to robots expected to remain in your long-term attack army, such as your highest-rarity pulls.
Q: How do redeem codes help with the Common to Mythic climb?
Codes like RELEASE and UPDATE provide Cash and Gems that accelerate early rolls and premium progression. Redeem them through the in-game Settings codes tab.
