Last War: Survival – Best Drone Chip Priority Guide

The best Last War drone chip priority for a main squad is generally Memory Ultra Fission first, Gravitational Resonance Armor second, Absolute Quantum Field third, and Lethal Firestorm fourth when crafting your first Legendary set.

Upgrade priority is slightly different. Build a complete UR set first, then work toward important star breakpoints across all four chips. Lethal Firestorm can temporarily move ahead of Absolute Quantum Field because its 2-star and 5-star upgrades improve the number of targets hit by drone attacks.

For a Tank main, use the Tank-aligned version of each chip. Aircraft and Missile players should follow the same basic logic but choose chips whose Unit Stats match their own main squad.

How the Last War Drone Skill Chip System Works

Drone Skill Chips are a mid-to-late-game layer of drone progression. They are separate from Drone Components, Drone Parts, and Battle Data.

The Skill Chip system unlocks when both conditions are met:

• Your server has been open for 82 days.
• Your Drone Combat Boost has reached level 10.

There are four Skill Chip categories:

• Initial Move
• Attack
• Interference
• Defense

Chips also carry Unit Stats for Tank, Aircraft, or Missile units. Matching those attributes to the formation using the preset is important because the corresponding unit type receives the relevant bonuses.

Best Last War Drone Chip Priority

Crafting Priority	Legendary Chip	Type	Main Value
1	Memory Ultra Fission	Interference	Suppresses important enemy tactic damage and provides strong main-squad combat value
2	Gravitational Resonance Armor	Defense	Provides sustained defensive value, with particular benefit to keeping the frontline alive
3	Absolute Quantum Field	Initial Move	Protects the formation during the opening burst with a shield and follow-up defensive effect
4	Lethal Firestorm	Attack	Improves drone offense and gains important multi-target upgrades at key stars

This is a crafting order, not a rule that Lethal Firestorm must always be your lowest upgrade priority. Chip star breakpoints change the order once you already own the full set.

1. Memory Ultra Fission — First Priority

Memory Ultra Fission is the Legendary Interference chip and is usually the best first UR chip for your primary formation.

Its value comes from influencing one of the most dangerous parts of combat: enemy tactic damage. Protecting your important damage dealers from heavy skill-based attacks can improve both survivability and total damage dealt over the course of a battle.

Prioritize Memory Ultra Fission when:

• You are crafting your first Legendary chip.
• Your squad frequently loses heroes to tactic-heavy burst.
• You are developing a PvP-focused main formation.
• You can upgrade it to the next meaningful star breakpoint.

Choose the Tank, Aircraft, or Missile-aligned version that matches the squad you plan to keep as your main formation.

2. Gravitational Resonance Armor — Second Priority

Gravitational Resonance Armor is the Legendary Defense chip. Unlike an effect that only protects the opening seconds of combat, its defensive benefit remains useful throughout the fight.

That makes it particularly valuable when your frontline dies before your back-row heroes can complete enough skill cycles.

Move Gravitational Resonance Armor high on your upgrade list when:

• Your front two heroes are consistently dying first.
• You fight opponents with similar or greater squad power.
• Your damage is already adequate but your formation cannot survive.
• You are building a durable Tank formation.

3. Absolute Quantum Field — Third Priority

Absolute Quantum Field is the Legendary Initial Move chip. Its main purpose is to protect your squad at the beginning of combat, helping absorb the first wave of enemy pressure before normal skill rotations are fully underway.

It is especially valuable when battles are being decided during the opening burst rather than later in the fight.

Absolute Quantum Field becomes more important when:

• Your frontline collapses almost immediately.
• You frequently face high-opening-damage PvP formations.
• Your existing sustained defense is already strong.
• Lethal Firestorm is not close to one of its major star breakpoints.

4. Lethal Firestorm — Attack Chip Priority

Lethal Firestorm is the Legendary Attack chip. It improves drone offense and becomes significantly more attractive when star progression expands the number of targets your drone can hit.

The important early breakpoints are:

• 2 stars: gains an additional drone target.
• 5 stars: gains another target, allowing the drone attack to hit three targets.

Because of these breakpoints, Lethal Firestorm may be the fourth chip you craft but the third chip you upgrade.

If it is one promotion away from 2 stars or 5 stars, finishing that milestone can provide more practical value than putting the same materials into Absolute Quantum Field.

Best Last War Tank Drone Chip Priority

For players searching specifically for the Last War Tank drone chip priority, the safest starting point is a complete Tank-aligned Legendary set.

1. Tank Memory Ultra Fission — first craft and usually first defensive/offensive utility priority.
2. Tank Gravitational Resonance Armor — reinforces formation durability and frontline survival.
3. Tank Absolute Quantum Field — protects against strong opening pressure.
4. Tank Lethal Firestorm — completes the UR set and becomes more important at its target-count star milestones.

This same structure also works for Aircraft and Missile mains: match the Unit Stats to the squad that will actually use the preset instead of automatically crafting Tank chips just because Tank is common during early progression.

What If You Plan to Switch From Tank to Aircraft?

If a troop-type switch is approaching, avoid overinvesting in a second deep Tank chip set unless it still has a clear use for another squad. Premium Chip Material is better spent on chips that will remain relevant after the transition.

You can create multiple Chip Presets as Combat Boost progresses, so long-term accounts eventually have room to support several troop types. Early and mid-game players, however, should concentrate resources on the squad that wins their most important battles.

Best Drone Chip Star Upgrade Order

Once the four Legendary chips are equipped, do not push one chip far ahead while the other three remain undeveloped. Balanced milestone progression generally produces better overall value.

A practical early progression path is:

1. Get Memory Ultra Fission to 2 stars.
2. Get Gravitational Resonance Armor to 2 stars.
3. Get Lethal Firestorm to 2 stars for its target breakpoint.
4. Get Absolute Quantum Field to 2 stars.
5. Work the set toward 5 stars, prioritizing meaningful breakpoints rather than perfect visual uniformity.
6. Complete Lethal Firestorm’s 5-star target upgrade when practical.

What About Chips Above 5 Stars?

Later chip progression on older or more advanced servers can extend beyond the original 5-star framework. Current late-game strategy references commonly treat 8 stars as another meaningful point before the most expensive late upgrades.

If your server displays this extended progression, use the same principle: bring the important chips toward the next breakpoint instead of pouring every duplicate into a single slot. If your interface does not yet show the same progression, follow the star preview displayed in your game.

Should All Four Drone Chips Have the Same Stars?

They should remain reasonably close, but they do not need to be identical at all times.

Balanced progression is best when:

• No chip is close to a major skill breakpoint.
• Several chips remain at a very low star level.
• You need both damage and survivability.
• The next upgrades have similar costs.

Focused progression is better when:

• Lethal Firestorm is one promotion from an extra target.
• Memory Ultra Fission is close to a stronger tactic-damage effect.
• A defensive upgrade directly addresses why you are losing battles.
• You already have enough duplicates to finish the milestone.

The goal is not perfect symmetry. It is avoiding a situation where one chip consumes months of materials while the rest of the main set remains underdeveloped.

Last War Chip Lab Priority

The Chip Lab is where you craft and manage Drone Skill Chips. Current reference data lists the first Legendary recipe at Chip Lab level 15 and all Legendary recipes as available by level 20.

That makes level 20 the important crafting target. Upgrading farther can still be part of normal base development, but you do not need higher Chip Lab levels simply to unlock another core Legendary chip recipe.

After reaching level 20, compare the cost of another Chip Lab upgrade against more urgent buildings such as your Tech Center, troop-specific centers, Barracks, Drill Grounds, or Headquarters prerequisites.

For building costs, resets, recipe unlocks, and additional details, see the Last War Chip Lab guide.

Combat Boost Priority and Chip Presets

Combat Boost is not just a source of raw Drone stats. It also controls access to Skill Chips, additional presets, and higher Chip Skill Boosts.

Combat Boost	Important Unlock
Level 10	Skill Chip system and first Chip Preset
Level 150	Second preset and Chip Skill Boost +1
Level 300	Third preset and Chip Skill Boost +2
Level 450	Fourth preset and Chip Skill Boost +3
Level 600	Chip Skill Boost +4
Level 750	Chip Skill Boost +5

Use unwanted Data Chips to increase Combat Boost. Do not sacrifice an Epic chip that is still filling an active slot, but once a UR replacement is equipped, obsolete lower-rarity chips can become useful progression material.

Do Chip Presets Matter?

Yes. Owning strong chips does not help if the wrong preset is assigned to the squad entering battle.

Preset handling also varies by game mode:

Battle Mode	Preset Consideration
World Map battles	Uses the chip preset configured with the relevant squad.
Storm Arena / 3v3 Brawl	Assault and defense formations may require their own preset assignments.
Intercity Trade / Trucks	Check the preset when dispatching or raiding trucks.
Alliance Train	Defense and raid configurations may require separate attention.

Recheck presets after changing your formation from Tank to Aircraft or Missile. A strong chip sitting in the wrong preset is effectively wasted for the battle you care about.

What Should You Do With Epic, Rare, and Lower-Rarity Chips?

Epic / SSR Chips

Epic chips are useful as temporary equipment while you build a Legendary set. Do not feed an Epic chip into Combat Boost if doing so creates an empty or clearly weaker slot in your active main preset.

Once its Legendary replacement is ready, the old Epic chip becomes a much better candidate for Combat Boost progression.

Lower-Rarity Chips

Lower-rarity chips have less long-term value as equipped options. Unwanted chips can be fed into Combat Boost, which strengthens the Drone and eventually unlocks additional presets and Chip Skill Boost levels.

Before consuming anything, make sure it is not part of a preset used by another squad.

Last War Skill Chip Chests Explained

Skill Chip Chests are useful for two reasons: they provide a chip and also award Premium Chip Material used to craft Legendary chips.

Skill Chip Chest	Guaranteed Premium Chip Material	Chip Reward
R	1	Random R or higher Skill Chip
SR	5	Random SR or higher Skill Chip
SSR	30	Random SSR or UR Skill Chip
UR	100	UR Skill Chip
UR Selection Chest	100	Selected UR Skill Chip

Because each crafted Legendary chip requires 800 Premium Chip Material, chest openings contribute directly toward your next targeted UR craft even when the random chip itself is not the one you need.

When Should You Open Chip Chests?

If your server’s Alliance Duel task list awards points for opening Drone Data Chip Chests, save them for the appropriate VS day rather than opening each chest immediately. On the standard schedule this activity appears on Day 1, but always check the current event objective because server age and event rules can affect what is available.

Do not confuse Skill Chip Chests with Drone Component Chests. They support different parts of drone progression and can be scored on different Alliance Duel days.

Basic vs. Premium Chip Material

There are two separate crafting resources:

• Basic Chip Material is used to craft Epic/SSR Skill Chips.
• Premium Chip Material is used to craft Legendary/UR Skill Chips.

They should not be treated as interchangeable resources. If you are already transitioning into UR chips, prioritize Premium Chip Material because it directly advances your permanent main set.

For farming options, see the Last War Basic Chip Material guide and Last War Premium Chip Material guide.

Should You Build Drone Chips for Every Squad?

Not at the beginning. Completing one strong set provides more practical value than spreading Premium Chip Material across several incomplete presets.

A sensible progression order is:

1. Complete four usable chips for your main squad.
2. Replace the main squad’s SSR chips with UR chips.
3. Reach efficient star milestones on all four main chips.
4. Build a functional second-squad set.
5. Return to deeper main-squad stars when the material cost still offers good value.
6. Develop the third and fourth presets as Combat Boost and account progression justify them.

Players who prefer to start with more developed heroes, Drone progression, and established chip presets can optionally compare a Last War account for sale. Check each listing individually because Drone levels, chip stars, troop types, and other progression can differ significantly between accounts.

F2P Drone Chip Priority

F2P players should be especially strict about concentrating Premium Chip Material.

Prioritize:

1. Your permanent main troop type.
2. Your first Memory Ultra Fission.
3. Gravitational Resonance Armor.
4. A complete four-chip UR set.
5. Efficient 2-star and 5-star breakpoints.
6. Combat Boost using chips you no longer need.

Avoid crafting random UR duplicates simply because you have 800 Premium Material available. Wait until the craft either completes a missing slot or advances a meaningful star milestone.

Spender Drone Chip Priority

Spenders can develop several presets sooner, but the same efficiency rules still apply. Purchasing more materials does not make a mismatched troop-type chip or poorly timed duplicate a good investment.

Finish the main formation first, then build the troop type used by your second competitive squad. UR choice chests are particularly valuable when they let you finish an exact star breakpoint instead of relying on random drops.

How Drone Chips Fit Into Overall Drone Progression

Skill Chips are only one part of the Drone. Your final battle performance also depends on:

• Drone level
• Battle Data
• Drone Parts
• Drone Components
• Combat Boost
• Chip rarity and stars
• Correct Chip Presets

Do not neglect core Drone levels just because a new Legendary chip provides an immediate power increase. After Drone level 150, Drone Parts become particularly important for continued leveling.

The Last War Drone Parts guide covers that progression resource in more detail.

Common Drone Chip Priority Mistakes

Crafting for the Wrong Troop Type

If your main formation is Aircraft, repeatedly crafting Tank-aligned chips wastes the Unit Stats synergy you actually need. Decide which formation you are investing in before using Premium Chip Material.

Upgrading Lethal Firestorm Without Watching Breakpoints

The Attack chip becomes much more attractive near its additional-target upgrades. Do not rank it permanently fourth without checking its next star effect.

Maxing One Chip While Ignoring the Other Three

Deep investment into a single chip can leave the rest of your preset too weak. Reach efficient milestones across the whole set.

Feeding Useful Epic Chips Into Combat Boost Too Early

Keep SSR chips that are still equipped. Convert them into Combat Boost progress after they have been replaced by permanent UR options.

Ignoring Chip Preset Assignments

A strong Tank set assigned to the wrong formation will not optimize the battle you intended to improve. Recheck presets after changing squads or entering modes with separate attack and defense configurations.

Opening Every Chip Chest Immediately

If Drone Data Chip Chest opening is part of the active Alliance Duel Day 1 objectives, waiting lets the same chests provide both their normal rewards and event points.

FAQs

What is the best Last War drone chip priority?

For the first Legendary set, prioritize Memory Ultra Fission, Gravitational Resonance Armor, Absolute Quantum Field, and then Lethal Firestorm. During star upgrades, Lethal Firestorm can move above Absolute Quantum Field when its next promotion reaches an important target-count breakpoint.

What is the best Tank chip set priority in Last War?

For a Tank main, build Tank-aligned Memory Ultra Fission first, followed by Gravitational Resonance Armor, Absolute Quantum Field, and Lethal Firestorm. Keep the whole set reasonably balanced as you increase stars.

When do Drone Skill Chips unlock?

The Skill Chip system unlocks after the server has been open for 82 days and your Drone Combat Boost reaches level 10.

What Chip Lab level should I prioritize?

Level 20 is the important crafting target because all Legendary chip recipes are available by that point. You can upgrade farther later, but higher levels are not required to unlock another core UR recipe.

Should Lethal Firestorm be upgraded before Absolute Quantum Field?

It can be. Lethal Firestorm gains additional drone targets at important star milestones, so prioritize it when you are close to those breakpoints. Otherwise, Absolute Quantum Field’s opening protection may provide more immediate value.

What should I do with old Epic drone chips?

Use Epic chips until you have Legendary replacements. Once an Epic chip is no longer needed by an active preset, it can be used to advance Combat Boost.

Conclusion

The best Last War drone chip priority is to finish a strong, troop-matched main set before spreading resources across several squads. Start with Memory Ultra Fission and Gravitational Resonance Armor, add Absolute Quantum Field and Lethal Firestorm, then upgrade around meaningful star breakpoints rather than blindly keeping every chip identical.
