Last War: Survival – Get Synthetic Resin & Epic Gear

Synthetic Resin is a gear crafting material in Last War: Survival. You can use it to craft Epic gear or merge 4 Synthetic Resins into 1 Dielectric Ceramic, which is needed for Legendary gear crafting and later Legendary gear promotion.

The most reliable long-term path is to collect lower-tier materials and merge upward: Screws → Refined Iron Modules → Superalloy → Synthetic Resin → Dielectric Ceramic. Synthetic Resin can also come indirectly from Gear Material Chests and dismantled gear, while Alliance Duel, Wanted Boss, stores, events, and selected packs provide additional opportunities.

What Is Synthetic Resin in Last War?

Synthetic Resin sits near the top of the normal gear-material conversion chain. It becomes relevant once you begin working with Epic equipment and preparing for Legendary gear.

Gear crafting and material management take place in the Gear Factory. The building itself unlocks when your Headquarters reaches level 9, but its important gear milestones are:

Gear Factory Level	Important Unlock
1	Rare Gear
5	Epic Gear
10	Legendary Gear
20	Legendary Gear Promotion

This distinction matters because unlocking the Gear Factory at HQ9 does not immediately mean every gear rarity is available. You need to continue upgrading the building before crafting Epic and Legendary equipment.

How to Get Synthetic Resin in Last War

There is no single source you should depend on. The fastest progression comes from combining passive material production, merging, gear dismantling, daily or weekly activities, and store opportunities.

1. Merge 4 Superalloys Into 1 Synthetic Resin

The most predictable way to create Synthetic Resin is through the Gear Factory’s Merge function. The conversion is:

4 Superalloys → 1 Synthetic Resin

Superalloy itself comes from Refined Iron Modules, so even very low-tier crafting materials contribute to your eventual Synthetic Resin and Dielectric Ceramic supply.

2. Produce Screws in the Material Workshop

The Material Workshop produces Screws over time. Screws are the starting material for the entire normal gear-material chain.

Upgrading your Material Workshops increases Screw production, giving F2P players a steady passive source of materials that can eventually be converted into Synthetic Resin.

Passive Screw production is slow compared with receiving finished gear or materials from rewards, but it runs continuously and becomes meaningful over long periods.

3. Get Refined Iron Modules From Gear Material Chests

Gear Material Chests are especially relevant if you are searching for Refined Iron Modules in Last War. Current reference data lists Plunder Gear Material Chests as a source of Refined Iron Modules.

Those modules are not Synthetic Resin yet, but you can merge them through the normal chain:

4 Refined Iron Modules → 1 Superalloy → 4 Superalloys → 1 Synthetic Resin

This makes Gear Material Chests an indirect but useful Synthetic Resin source. Do not judge a chest only by whether it contains Resin directly; lower-tier materials still contribute to the same end goal.

4. Dismantle Unneeded Gear

The Gear Factory can dismantle unwanted equipment and return crafting materials. This is one of the most useful ways to convert gear you no longer need into progress toward Legendary equipment.

Before dismantling an Epic item, make sure it is not still useful on a main or secondary hero. Once your important heroes have better replacements, unused lower-rarity equipment becomes much easier to recycle.

5. Use Intercity Trade Gear Chests

Intercity Trade Gear Chests can provide equipment that may be equipped temporarily or dismantled for crafting materials. This creates another route to Synthetic Resin without crafting every component from Screws.

Gear that does not improve any useful squad can effectively become material progression instead of sitting unused in your inventory.

6. Participate in Alliance Duel

Alliance Duel is an ongoing source of valuable progression rewards, and current reward references include Synthetic Resin among the materials available through higher-level participation and league progression.

For F2P players, consistent participation is more sustainable than relying on packs because the event repeats and rewards many other resources at the same time.

7. Fight Wanted Bosses

Wanted Boss is another current activity that can reward Synthetic Resin alongside Upgrade Ore and other progression materials. Because Wanted Boss is a recurring PvE activity, participating consistently can add to your long-term gear-material supply.

Use the troop type that matches the boss weakness and focus on damage rather than defensive stats, since higher damage improves your ranking opportunities.

8. Check the Alliance and VIP Stores

Synthetic Resin is also listed as obtainable through the Alliance Store and VIP Store. The VIP Store source requires VIP6, but VIP6 is not required to obtain Synthetic Resin overall.

Store inventories and purchasing priorities can change as your account develops, so compare Resin with other high-value items before spending scarce currency. The Last War VIP guide covers the wider benefits of VIP progression.

9. Watch Events and Limited Shops

Events and temporary shops can add more Synthetic Resin or related gear materials to your supply. Current examples of repeatable gear-material sources include activities such as Zombie Invasion trade periods and other event reward systems.

Check the Last War Event Hub before spending event currency so you can compare Synthetic Resin with competing rewards.

Last War Gear Material Conversion Chain

The full conversion chain is one of the most important details to understand, especially because search results and older guides sometimes shorten Refined Iron Module to just “Refined Iron.” The in-game material name used in the current crafting chain is Refined Iron Module.

Material	Merge Recipe	Equivalent Screws	Main Role
Screw	4 → 1 Refined Iron Module	1	Base material from Material Workshop
Refined Iron Module	4 → 1 Superalloy	4	Lower-tier gear material
Superalloy	4 → 1 Synthetic Resin	16	Rare gear material and Resin precursor
Synthetic Resin	4 → 1 Dielectric Ceramic	64	Epic gear and Legendary material progression
Dielectric Ceramic	Highest material in this merge chain	256	Legendary gear crafting and promotion

What Is a Refined Iron Module?

A Refined Iron Module is the first merged material above Screws. You create one by combining four Screws in the Gear Factory.

The normal path is:

4 Screws → 1 Refined Iron Module

Then:

4 Refined Iron Modules → 1 Superalloy

Because Gear Material Chests can provide Refined Iron Modules, they effectively save part of the passive Screw-production process. This is why Gear Material Chests remain useful even after you have progressed beyond low-rarity equipment.

What Is Dielectric Ceramic Used For?

Dielectric Ceramic is the material above Synthetic Resin in the normal gear-material chain.

You create it at the Gear Factory by merging:

4 Synthetic Resins → 1 Dielectric Ceramic

Dielectric Ceramic is required for Legendary gear crafting and becomes an even larger bottleneck once you begin promoting level-40 Legendary equipment through star levels.

That is why Synthetic Resin should not be viewed only as an “Epic gear material.” For developed accounts, its more important long-term purpose is often conversion into Dielectric Ceramic.

Should You Craft Epic Gear With Synthetic Resin?

Usually, not unless you have a clear reason.

Epic gear is useful during early and mid-game progression, but it can also be obtained through normal gameplay. Reliable gear guides therefore recommend saving crafting materials for Legendary equipment whenever your account is already approaching that stage.

Craft Epic Gear When:

• A main-squad hero still has an empty or weak equipment slot.
• The Epic item provides an immediate and meaningful combat improvement.
• Legendary gear is still far beyond your current progression.
• You expect to move the Epic piece to a secondary hero later.

Save the Synthetic Resin When:

• Your main heroes already have functional Epic gear.
• Gear Factory level 10 and Legendary crafting are approaching.
• You already have Legendary pieces that will eventually need Dielectric Ceramic for promotion.
• The proposed Epic item would only provide a minor temporary improvement.

How to Dismantle Gear Efficiently

Dismantling is valuable, but only when the gear genuinely has no useful role left.

Before dismantling an item, check whether it can still serve:

• A hero in your second squad.
• A newly unlocked hero.
• A temporary formation for an event.
• A hero waiting for a future Legendary replacement.

If none of those apply, dismantling converts dead inventory into materials you can merge toward stronger gear.

Avoid continuing to invest Upgrade Ore into equipment you already expect to dismantle soon. Gear crafting materials and Upgrade Ore are different bottlenecks, so wasting both on temporary equipment slows progression twice.

Can You Disintegrate Gear Materials?

Yes. The Gear Factory also supports Disintegrate, which reverses the merge chain. For example, one Dielectric Ceramic can be broken down into four Synthetic Resins, and the same 4-to-1 relationship works backward through the lower materials.

This is useful if you merged too aggressively and later discover that you need a lower-tier material. However, constantly merging and reversing materials creates unnecessary inventory management, so it is better to plan your target gear first.

Best Synthetic Resin Strategy for F2P Players

F2P players should focus on repeatable sources and avoid spending valuable materials for small temporary gains.

1. Keep Material Workshops productive: Passive Screws eventually become higher-tier gear materials.
2. Prioritize Gear Material Chests when the reward value is good: Refined Iron Modules skip several hours of basic production.
3. Dismantle surplus gear: Recycle equipment once you are sure no active squad needs it.
4. Participate in Wanted Boss: It is a recurring opportunity to earn gear-related materials.
5. Complete Alliance Duel objectives: Strong weekly participation adds Synthetic Resin and other progression resources over time.
6. Save toward Legendary gear: Avoid repeatedly crafting Epic items after your main squad has functional equipment.
7. Concentrate on one squad first: Twenty mediocre gear pieces spread across several squads usually provide less useful progress than strengthening your primary five heroes.

Which Gear Should You Prioritize?

Gear priorities depend on the hero’s role. Attack-oriented heroes generally gain the most immediate value from offensive equipment such as the Railgun/Cannon and Chip, while frontline defenders benefit heavily from Armor and Radar.

Do not craft gear simply because you have enough material. Decide which hero and equipment slot will receive the item before committing Synthetic Resin or Dielectric Ceramic.

Common Synthetic Resin Mistakes

• Calling Refined Iron Module “Refined Iron”: Refined Iron Module is the gear material used in the crafting chain.
• Expecting Gear Material Chests to be only about Synthetic Resin: Their Refined Iron Modules can be merged upward into Resin.
• Crafting too much Epic gear: Epic equipment is obtainable through gameplay, while your materials are eventually needed for Legendary progression.
• Dismantling useful Epic gear too early: A piece that is weak for your first squad may still fill an important slot on squad two.
• Ignoring Material Workshops: Screw production is slow, but it is a permanent passive source of crafting materials.
• Spreading gear across too many heroes: Your primary squad normally benefits more from concentrated investment.
• Confusing crafting with upgrading: Synthetic Resin and Dielectric Ceramic are crafting materials; gear levels also require separate resources such as Coins and Upgrade Ore.
• Ignoring future promotion costs: Dielectric Ceramic continues to matter after Legendary gear has been crafted.

How Synthetic Resin Fits Into Long-Term Gear Progression

Synthetic Resin is a transition material between early gear crafting and the much more expensive Legendary equipment stage. Early accounts may use it directly for an Epic piece, while developed accounts usually merge most of it into Dielectric Ceramic.

The long-term progression path is generally:

1. Use rewarded Rare and Epic equipment while progressing.
2. Produce and collect lower-tier crafting materials.
3. Merge materials toward Synthetic Resin and Dielectric Ceramic.
4. Reach Gear Factory level 10 to craft Legendary gear.
5. Replace temporary Epic equipment on your primary heroes.
6. Bring important Legendary equipment toward level 40.
7. Reach Gear Factory level 20 and begin Legendary star promotion when your material supply supports it.

Players who prefer starting with an already-developed roster and gear inventory can also browse Last War accounts for sale as an optional progression path. For players developing their own account, preserving crafting materials for permanent gear is usually the more important long-term decision.

FAQs

How do you get Synthetic Resin in Last War?

You can merge four Superalloys into one Synthetic Resin. Other sources include Plunder Gear Material Chests indirectly through Refined Iron Modules, dismantled gear from Intercity Trade and other rewards, Alliance Duel, Wanted Boss, the Alliance Store, the VIP Store at VIP6, events, and selected packs.

What is a Refined Iron Module in Last War?

Refined Iron Module is a lower-tier gear material. Four Screws merge into one Refined Iron Module, and four Refined Iron Modules merge into one Superalloy. Sixteen Refined Iron Modules are therefore equivalent to one Synthetic Resin.

What does a Gear Material Chest give in Last War?

Gear Material Chests obtained through Plunder are listed as a source of Refined Iron Modules. Those modules can be merged into Superalloy and then Synthetic Resin, so the chest contributes directly to higher-tier gear-material progression even when it does not give finished Resin.

How many Synthetic Resins make one Dielectric Ceramic?

You need 4 Synthetic Resins to merge one Dielectric Ceramic. That is equivalent to 16 Superalloys, 64 Refined Iron Modules, or 256 Screws.

Should I craft Epic gear with Synthetic Resin?

Only when the Epic item provides a meaningful immediate upgrade. Once your main squad has usable Epic gear and Legendary crafting is approaching, saving Resin for Dielectric Ceramic is generally more efficient.

Do you need VIP6 to get Synthetic Resin?

No. VIP6 unlocks Synthetic Resin as a VIP Store source, but Resin can also be obtained without direct spending through material merging, gear dismantling, Alliance Duel, Wanted Boss, other events, and earned store currencies.

Conclusion

The best way to manage Last War Synthetic Resin is to understand the full crafting chain rather than treating Resin as a standalone item. Keep producing Screws, collect Refined Iron Modules and Superalloy, dismantle gear you no longer need, and use recurring activities to supplement your supply. Craft Epic gear only when it fills a real gap; otherwise, preserve Synthetic Resin for Dielectric Ceramic and long-term Legendary gear progression.
