Premium Chip Material in Last War: Survival is used in the Chip Lab to craft UR (Legendary) Drone Skill Chips. One UR Skill Chip currently costs 800 Premium Chip Material, so crafting a complete four-chip UR preset from materials alone requires 3,200.
The most reliable sources include Alliance Duel rewards and Skill Chip Chests obtained through stores, alliance activities, Ghost Ops, events, profession skills, and other reward systems. Higher-rarity chests give substantially more Premium Chip Material, so understanding the current R/SR/SSR/UR chest system is important for efficient farming.
★Quick Take: Save 800 Premium Chip Material for a specific UR chip that matches your main squad instead of crafting randomly. Skill Chip Chests provide 1, 5, 30, or 100 Premium Material depending on rarity, and Alliance Duel provides another recurring route to building your stockpile.
What Is Premium Chip Material?
Premium Chip Material is the high-tier crafting currency for Drone Skill Chips. It is spent in the Chip Lab when producing UR chips, the gold-rarity chips that form the long-term target for developed formations.
Current Chip Lab references list the following crafting cost:
- 1 UR Skill Chip: 800 Premium Chip Material
- 4 UR Skill Chips: 3,200 Premium Chip Material if every chip is crafted
That second total represents one complete four-slot preset. In practice, you may need fewer crafting materials if you obtain useful UR chips directly from Skill Chip Chests, choice chests, events, or stores.
Premium Chip Material remains useful after your first UR set because duplicate chips are used in later chip development. Do not treat 3,200 as the point where the resource permanently stops mattering.
When Do Drone Skill Chips Unlock?
The Skill Chip system is not available from the beginning of the game. Current official Last War guidance states that it unlocks when both of these conditions are met:
- Your server has been open for 82 days.
- Your Drone Combat Boost has reached level 10.
This is separate from Drone Components, which unlock much earlier. Players often confuse the two systems because both are part of Drone progression.
Once Skill Chips are available, the Chip Lab lets you craft chips using Basic and Premium Chip Material. Current Chip Lab data indicates that the first UR recipes become available at higher building levels, with all UR recipes available by Chip Lab level 20.
For the full building and crafting system, see the Last War Chip Lab guide.
How to Get Premium Chip Material in Last War
There is no single farming method that supplies enough Premium Chip Material on its own. Efficient accounts combine recurring Alliance Duel rewards with Skill Chip Chests, stores, alliance content, professions, and temporary events.
Alliance Duel Rewards
Alliance Duel is one of the most dependable recurring sources once the Skill Chip system is relevant to your server.
Current Alliance Duel guides list Premium Chip Material at three daily point milestones:
- 540,000 points: 10 Premium Chip Material
- 2,300,000 points: 10 Premium Chip Material
- 7,200,000 points: 10 Premium Chip Material
Reaching all three provides 30 Premium Chip Material from those milestones. Always confirm your live Alliance Duel chest contents because reward structures can change with server progression or future updates.
Once Skill Chips are unlocked, earning Premium Chip Material can also contribute to the relevant Alliance Duel scoring task, making planned chest opening useful for both chip progression and event points.
The Last War Alliance Duel guide explains how to coordinate your other weekly actions with the correct scoring days.
Skill Chip Chests
Skill Chip Chests are one of the most important Premium Material sources because each chest provides both a Skill Chip and a guaranteed amount of Premium Chip Material.
Current versions use R, SR, SSR, and UR rarity labels. Older guides may describe these as Common, Rare, Epic, and Legendary.
| Skill Chip Chest | Premium Chip Material | Chip Reward |
|---|---|---|
| R | 1 | Random R, SR, SSR, or UR chip |
| SR | 5 | Random SR, SSR, or UR chip |
| SSR | 30 | Random SSR or UR chip |
| UR | 100 | Random UR chip |
| UR Skill Chip Choice Chest | 100 | Choose an available UR chip |
The UR Choice Chest is particularly valuable because it combines 100 Premium Material with control over the chip received instead of relying on a random UR result.
Alliance Store
Skill Chip Chests can appear in the Alliance Store. This provides a repeatable route to Premium Material using alliance currency rather than premium purchases.
Do not buy automatically. Compare the chest with other items your account urgently needs before committing limited Alliance Store currency.
VIP Store
The VIP Store can also provide Skill Chip Chests. Their value increases once UR chip crafting is a genuine progression bottleneck, but your exact purchase priority depends on the other resources available to your account.
Honor and Campaign Stores
Skill Chip-related rewards may also appear in the Honor and Campaign Stores. Current guides list higher-rarity chests in the Honor Store and lower-rarity options through Campaign progression.
Even low-rarity chests contribute Premium Material over time, but avoid sacrificing a more important limited store item merely to gain one or five materials.
Zombie Invasion
The Zombie Invasion Trade Store can offer Skill Chip Chests during the event. SR and SSR chests are particularly useful because they provide both chip rolls and Premium Material.
Event inventories can change, so compare the active trade-store rewards rather than assuming the same chest is available every cycle.
Engineer Drone Supply
The Engineer profession includes the Drone Supply skill, which can provide Skill Chip Chests. These are not individually large Premium Material rewards, but recurring profession income contributes over a long period without consuming normal store currency.
Alliance Exercise
Higher Alliance Exercise levels can include Skill Chip Chests. Current community references list SR and SSR chests among the upper-level rewards.
This is another reason active alliances have an advantage in chip progression: stronger alliance participation improves access to reward tiers that are difficult to reach alone.
Ghost Ops
Ghost Ops can award Skill Chip Chests as special rewards. The exact rarity is not guaranteed, so treat Ghost Ops as a supplementary source rather than a predictable daily amount of Premium Material.
Black Market
During the post-season Black Market event, UR Skill Chip and UR Skill Chip Choice Chests can appear among the available rewards. Current 2026 Black Market data confirms that these chests also grant 100 Premium Chip Material when obtained and opened.
Because Black Market inventories are random and seasonal, treat UR chips as high-value opportunities rather than a guaranteed source every event.
Meteorite Iron War and Other Events
Premium Chip Material can also appear in temporary events. Meteorite Iron War is one current example where Premium Material is included among potential rewards.
Other special events, passes, exchanges, and milestone tracks may provide direct Premium Material or Skill Chip Chests. Always inspect the current event reward table before spending event currency.
How Many Skill Chip Chests Do You Need for 800 Materials?
If you tried to reach one 800-material UR craft using only one chest rarity, the totals would be:
| Chest Rarity | Material per Chest | Chests Needed for at Least 800 |
|---|---|---|
| UR | 100 | 8 |
| SSR | 30 | 27 |
| SR | 5 | 160 |
| R | 1 | 800 |
Twenty-six SSR chests provide only 780 materials, which is why the total must be rounded up to 27.
Real accounts normally combine Alliance Duel rewards, several chest rarities, event rewards, and direct Premium Material rather than farming 800 identical chests.
✓Recommendation: Track your remaining gap to 800 instead of counting chests. If you have 710 materials, for example, one UR chest completes the craft while three SSR chests also provide enough. Knowing the exact gap helps you choose stores and event rewards more efficiently.
Premium Chip Material vs. Basic Chip Material
Premium and Basic Chip Material are separate currencies and cannot be converted into each other.
| Material | Used For | Typical Crafting Cost |
|---|---|---|
| Basic Chip Material | SSR Skill Chips | 400 for most SSR chips; some recipes differ |
| Premium Chip Material | UR Skill Chips | 800 per UR chip |
Do not discard the value of Basic Chip Material simply because UR chips are stronger. SSR chips can fill empty slots while you save Premium Material and can later support Combat Boost progression after suitable UR replacements are available.
The Last War Basic Chip Material guide covers the separate SSR crafting economy.
Which UR Skill Chip Should You Craft First?
Premium Chip Material is too slow to collect for most players to spend 800 without a plan. Before crafting, check both the chip’s combat function and its unit-type attributes.
The current Skill Chip system contains four functional categories:
- Initial Move: affects the opening phase of battle.
- Attack: improves offensive Drone effects.
- Interference: provides offensive and enemy-disruption effects.
- Defense: improves survivability.
Chips can also have Tank, Aircraft, or Missile attributes. Match the relevant chip to the squad type you actually use. Crafting a UR chip for a troop type that is not part of your main formation can leave 800 materials tied up in an upgrade that provides much less immediate value.
Current community priority guides commonly place Memory Ultra Fission and Gravitational Resonance Armor among the first high-value UR crafts, followed by the remaining slots according to your squad and combat needs.
For a slot-by-slot explanation, use the Last War Drone Chip priority guide before committing your materials.
Best Premium Chip Material Strategy for F2P Players
Reach the Alliance Duel Material Chests
Recurring direct Premium Material is especially valuable to F2P players. Work toward the Alliance Duel point milestones your account can reach consistently rather than relying on occasional high-rarity drops.
Take Every Useful Free Chest
Alliance activities, profession rewards, Ghost Ops, event milestones, and other gameplay systems compound over time. A single R chest only gives one material, but regularly collecting free chests still advances both Premium Material and Combat Boost progression.
Be Selective With Store Currency
Do not buy a Skill Chip Chest merely because Premium Material is scarce. Compare the purchase with hero shards, Drone Parts, gear resources, and other account-specific bottlenecks.
Prioritize the Main Squad
Your first 800 materials should normally improve the formation you use for your most important PvP and PvE content. Building multiple incomplete troop-type presets too early spreads a scarce resource across too many projects.
Use SSR Chips While Saving
An SSR chip that fits your formation is better than leaving a slot weak or empty while waiting for enough materials to craft every UR replacement.
Should You Save Skill Chip Chests for Alliance Duel?
Once Skill Chip progression is active on your server, opening Skill Chip Chests generates Premium Chip Material. Alliance Duel can award points for gaining this material during the appropriate scoring day.
If you do not need to open a chest immediately, saving a stockpile until the matching Alliance Duel window can provide two benefits from the same chest:
- The Skill Chip and Premium Material itself
- Alliance Duel progress from the material gained
Check the current Duel task list before opening a large chest stockpile because scoring rules can be adjusted.
How to Spend Premium Chip Material Efficiently
Set a Specific 800-Material Target
Know exactly which UR chip and troop type you intend to craft before reaching 800. This prevents an impulsive craft from delaying the chip you actually needed.
Build One Useful Preset Before Spreading Out
A complete main-squad chip setup generally provides more practical value than starting several unfinished Tank, Aircraft, and Missile presets at the same time.
Do Not Ignore Direct UR Chip Drops
If an event or UR chest gives you the exact chip you intended to craft, reassess your plan. Your saved 800 materials may now be better spent filling another slot or preparing for future duplicates.
Check Chip Lab Recipe Availability
Having 800 Premium Material does not automatically mean every UR recipe is unlocked. Make sure your Chip Lab has reached the level required for the target recipe.
Plan Beyond the First Copy
UR chip development does not end after obtaining one copy of each chip. Ascension uses additional copies, so Premium Material remains a long-term progression currency.
!Important: Do not craft a chip only because you have reached 800 Premium Material. Check the troop type, slot, current UR chips, Chip Lab recipe access, and your next ascension goal first. Premium Material is slow enough to replace that a mismatched craft can delay meaningful progression.
Are Paid Premium Chip Material Packs Worth It?
Paid offers can include direct Premium Chip Material, Skill Chip Chests, Basic Material, Combat Boost EXP, or UR choice chests. Their contents and prices change, so there is no universal pack that is always worth buying.
Before spending, calculate:
- Your current Premium Material total
- How many materials remain until 800
- Whether the offer includes a useful UR or choice chest
- Whether the target chip matches your main squad
- Whether another resource is a bigger combat bottleneck
An offer that takes you from 760 to beyond 800 and immediately completes a useful UR craft has a different progression impact from one that only moves you from 100 to 150.
Players who prefer to begin from a more developed stage can optionally compare a Last War account for sale. Check the existing Drone Combat Boost, UR chip presets, chip stars, heroes, research, gear, and troop types rather than evaluating an account by raw Power alone.
Common Premium Chip Material Mistakes
- Using outdated chest terminology: current versions use R, SR, SSR, and UR; older guides often call the same tiers Common, Rare, Epic, and Legendary.
- Crafting the wrong troop-type chip: verify Tank, Aircraft, or Missile compatibility before spending 800 materials.
- Ignoring Alliance Duel: recurring VS milestones are one of the most predictable Premium Material sources.
- Opening all Skill Chip Chests immediately: when possible, align chest opening with the relevant Alliance Duel scoring window.
- Buying every low-rarity chest: one Premium Material is useful, but store currency may have a better use.
- Spreading materials across several squads too early: finish a useful main-squad setup before chasing multiple troop-type presets.
- Assuming 3,200 materials finishes the system forever: duplicate UR chips remain relevant for later chip development.
- Confusing Basic and Premium Material: they have separate crafting purposes and cannot be converted into each other.
