Complete Drone Guide

What the drone actually does

The drone joins combat automatically and cannot be targeted like a hero. It contributes its own damage while also adding attributes to the heroes in the squad. That makes it both a sixth source of battlefield pressure and a permanent account-wide development system.

A large drone power number does not explain where the advantage comes from. Open the drone and separate these four layers:

Drone levels: Battle Data versus Drone Parts

Normal development consumes Battle Data. Up to Level 150, Drone Parts are required at every fifth level: 5, 10, 15 and so on. After Level 150, parts become an every-level requirement, so the bottleneck changes sharply. Do not spend parts without knowing the next complete level target.

The live screen divides a breakthrough into stages. A source may describe the cost per stage while another lists the total across all stages. Always check which figure you are reading before planning.

When should you spend Drone Parts?

Alliance Duel normally rewards drone development on Day 1, Radar Training. If waiting will not block an urgent combat milestone, bank Battle Data and Drone Parts and apply them during the scoring window. You gain the same permanent upgrade plus VS points.

Do not delay a critical event fight for days merely to optimise a small score, and do not empty every reserve just because the VS button is glowing. The correct rhythm is: choose the next finished drone level, save its resources, spend on the matching day, then rebuild the reserve.

The six drone components

Components are separate from drone level. Six equipped pieces add hero attributes, and three identical components of one level merge into a single component at the next level. Because every merge consumes three, the real cost grows exponentially.

Use choice chests to repair imbalance. Do not automatically feed the component that is already furthest ahead. Check the six equipped levels and direct controlled rewards toward the lagging high-value slot. A broad formation benefits from Attack, HP and Defence together; one oversized offensive component cannot compensate for a frontline that disappears immediately.

Component chests normally score on Alliance Duel Day 3, Age of Science. Keep unopened chests for that day when the event rules shown on your server confirm it.

Skill chips: four different jobs

Skill chips are not ordinary components. They equip into four defined slots and their effects run during combat. The names can vary with translation or release, but the jobs are consistent:

The troop-matched Interference chip is the easiest serious mistake to make. A strong Aircraft chip equipped behind a Tank formation may look impressive in the inventory but will not provide the intended Tank effect. Create and name presets for each developed squad rather than changing one preset from memory before every battle.

Chip rarity, crafting and resets

Keep useful Epic chips equipped until a real Legendary replacement is ready. Do not dismantle the working preset merely because the final build uses gold chips. The Chip Lab can craft, dismantle and reset chips, letting you recover invested development resources when the account changes direction.

Legendary recipes become available as the Chip Lab develops; current community data places the Initial Move recipe at Lab Level 15 and the remaining Legendary recipes by Level 20. Beyond the point where the required recipes are open, another combat building may deliver more value than rushing the Lab purely for its level.

A crafted Legendary chip commonly requires 800 Premium Chip Material. Treat that as a planned target. Randomly crafting for three formations at once delays the complete four-chip preset that the main squad can use every day.

Combat Boost and chip stars

Combat Boost strengthens the chip system and unlocks additional preset capacity at major thresholds. Feed unwanted chips only after protecting every chip currently used by an active formation. Lock important chips before dismantling or using bulk actions.

Chip stars and Combat Boost are visible in an English battle report. They are not cosmetic. A large gap can explain why two formations with similar-looking heroes perform very differently.

What the battle report proves

In this report the blue side has Combat Boost 354 against 255 and 17 chip stars against 8. Its component advantage produces larger hero HP, Defence and Attack additions. The Statistics screen then records the drone’s separate equivalent damage, allowing the development gap to be connected to an actual battle result.

How to diagnose your drone

A practical progression plan

Early account

1. Collect Battle Data and Drone Parts every day.
2. Raise the drone steadily and never miss an affordable five-level breakthrough.
3. Equip all six components and merge them broadly.
4. Build one coherent main formation before planning three chip presets.

Developing main squad

1. Bank parts for named targets and use them on VS Day 1.
2. Use component choice rewards to repair the weakest equipped slots.
3. Complete four chips for the main troop type; verify the Interference match.
4. Save before-and-after reports with the same preset.

Established and late game

1. Compare each post-150 drone level with the next component and chip breakpoint.
2. Build second and third presets only for squads that are genuinely used.
3. Push Combat Boost thresholds deliberately rather than sacrificing working chips.
4. Judge every expensive step by combat effect, not account power alone.

Reliable places to collect resources

• Daily play: Daily Tasks, radar and zombie activity provide steady development materials.
• Stores: Alliance, VIP and Campaign stores regularly offer drone-related items; compare them with your other scarce priorities.
• Alliance content: Alliance Duel, Alliance Exercise and event chests provide parts, components or chip materials.
• Rotating events: Zombie Invasion and other limited stores can be strong sources, but stock changes.
• Component Factory and Chip Lab: collect production and keep recipes aligned with the active plan.

Common mistakes

• Calling level, components, chips and Combat Boost the same upgrade.
• Using a troop-specific Interference chip with the wrong formation.
• Opening component chests immediately and losing easy VS points.
• Merging the strongest component repeatedly while another slot falls far behind.
• Dismantling useful Epic chips before their Legendary replacements exist.
• Feeding a working chip into Combat Boost by mistake.
• Splitting premium materials across three incomplete presets.
• Changing the drone preset during a hero test, making the result impossible to interpret.

Commander checklist

• I know my next complete drone-level target and total part requirement.
• All six components are equipped and choice chests repair the weakest useful slot.
• My Interference chip matches the main squad’s troop type.
• Every active preset has its important chips locked.
• I use the correct Alliance Duel day when waiting is sensible.
• I compare drone damage and hero attribute bonuses in battle reports.

Frequently asked questions

Should I choose Drone Parts or component chests?

Before Level 150, parts often unlock clear drone breakthroughs; near a component merge, a choice chest may produce the stronger immediate combat gain. After Level 150, compare the expensive every-level part requirement with the attributes gained from the next component. There is no permanent answer without seeing both progress bars.

Should components stay even?

They do not need identical levels, but avoid an extreme gap created by blindly merging the same slot. Use choice rewards to correct the weakest important attribute for the formation.

Does drone damage belong to my strongest hero?

No. The Statistics report lists equivalent drone damage separately. Keep it separate when judging Kimberly, DVA, Tesla or another carry.

Can one chip preset serve every formation?

General chips may still function, but the troop-specific Interference effect must match the formation. Proper Tank, Aircraft and Missile presets prevent avoidable mismatches.
