Last War Wanted Boss Guide: Code 39, 64 and 87 Strategy

The Wanted Boss in Last War is a recurring server-wide PvE damage event built around three monsters: Code 87 Frenzied Butcher, Code 64 Frankenstein, and Code 39 Mutant Bulldog. Each boss appears on specific days and takes 50% additional damage from one hero type, making formation choice the most important part of the event. You can challenge the active Wanted Boss up to five times per day. Instead of defeating the boss permanently, your objective is to produce the highest possible damage in a single attempt. Use the correct Tank, Missile, or Aircraft formation, concentrate offensive progression on your main damage dealers, and use your first attempts to test improvements before committing your final run.

Last War Wanted Boss Schedule

The three Wanted Bosses rotate from Monday through Saturday. Sunday has no Wanted Boss. Each active boss appears at four server-time windows: 00:00, 06:00, 12:00, and 18:00, with each appearance remaining available for three hours.

Day	Wanted Boss	Code	Use This Hero Type
Monday	Frenzied Butcher	Code 87	Tank
Tuesday	Frankenstein	Code 64	Missile Vehicle
Wednesday	Mutant Bulldog	Code 39	Aircraft
Thursday	Frenzied Butcher	Code 87	Tank
Friday	Frankenstein	Code 64	Missile Vehicle
Saturday	Mutant Bulldog	Code 39	Aircraft
Sunday	No Wanted Boss	—	—

You do not need to be online for every spawn window. The four appearances mainly give players in different time zones multiple opportunities to use their daily attempts.

Wanted Boss Rules

Commanders need at least Headquarters Level 8 to participate. You can make up to five challenges per day, and each battle lasts approximately 90 seconds. Your ranking is determined by your strongest single-attempt damage rather than the sum of all five attacks. The Wanted Boss is unusual because it does not function like a standard PvE enemy trying to destroy your formation. The encounter is primarily a timed damage test, which means offensive output matters much more than conventional survivability.

The 50% Wanted Boss Weakness Bonus

Every Wanted Boss has one major weakness:

• Code 87 Frenzied Butcher: Tank heroes deal 50% more damage.
• Code 64 Frankenstein: Missile Vehicle heroes deal 50% more damage.
• Code 39 Mutant Bulldog: Aircraft heroes deal 50% more damage.

This bonus should determine your first formation choice. If you normally use Tanks but Code 39 is active, an Aircraft squad can produce better results even when its displayed power is lower, provided those Aircraft heroes have received reasonable development.

Code 87 Frenzied Butcher Strategy

Frenzied Butcher appears on Monday and Thursday and is weak to Tank heroes. This is often the easiest Wanted Boss for players whose first developed formation is Tank-based. Useful Tank options include:

• Kimberly: Primary offensive option for many Tank-focused accounts.
• Mason: Strong PvE-oriented damage option, particularly once his later progression systems become available.
• Marshall: Valuable support that can improve the output of the rest of the squad.
• Stetmann: Another offensive option for accounts that have invested heavily in him.
• Williams or Murphy: Can fill remaining Tank slots while maintaining a full Tank formation.

Since the objective is damage rather than survival, prioritize your best attack-oriented equipment and development on heroes such as Kimberly and Mason before worrying about defensive optimization.

Code 64 Frankenstein Strategy

Frankenstein appears on Tuesday and Friday and takes 50% additional damage from Missile Vehicle heroes. Useful Missile heroes include:

• Tesla: One of the most important Missile damage dealers.
• Fiona: Strong additional damage for developed Missile formations.
• Swift: Provides useful damage and support within a Missile lineup.
• McGregor: Can contribute additional focused damage.
• Adam: Helps complete a full Missile formation when needed.

If Missile is normally your second or third formation, temporarily moving your best offensive equipment onto Tesla and Fiona can improve your Wanted Boss result without permanently changing your regular squad setup.

Code 39 Mutant Bulldog Strategy

Mutant Bulldog appears on Wednesday and Saturday and is weak to Aircraft heroes. Useful Aircraft options include:

• DVA: Primary Aircraft damage dealer for many developed accounts.
• Morrison: Strong offensive partner for DVA.
• Schuyler: Adds additional damage and utility.
• Carlie: Helps maintain a complete Aircraft formation.
• Lucius: Another natural Aircraft option for filling the squad.

For players who normally invest almost entirely in Tanks, Code 39 is often the Wanted Boss that exposes an underdeveloped secondary roster. Building DVA and other useful Aircraft heroes gradually can produce a significant improvement over repeatedly sending Tanks into an Aircraft-favored boss.

How to Build the Best Wanted Boss Squad

Use Five Matching Heroes When Practical

The boss weakness applies to the relevant hero type, while normal same-type formation bonuses also reward cohesive squads. Building around five appropriate Tank, Missile, or Aircraft heroes therefore gives you multiple reasons to avoid a random mixed formation. There can still be account-specific exceptions when one off-type hero is dramatically stronger or provides exceptional support, so use your actual damage records instead of assuming every theoretical lineup will perform identically.

Prioritize Damage Dealers

Wanted Boss is primarily an offensive benchmark. Your most important upgrade resources for this event should support the heroes responsible for the largest share of damage. That means prioritizing areas such as:

• Hero levels and important offensive skills
• Attack-focused Legendary Gear
• Gear promotion and offensive progression
• Drone development
• Skill Chips appropriate to the formation
• Tank, Aircraft, and Missile Center bonuses
• Exclusive Weapons where available
• Awakening and other later-season hero systems when unlocked

Because servers unlock progression systems at different times, newer accounts will not have access to every option listed above.

Move Gear Before Your Best Attempt

You do not need three completely separate sets of premium equipment to improve all three Wanted Boss days. If equipment can be reassigned on your account, move your strongest offensive pieces to that day’s primary damage dealers before making your important attempt. For example, your best Tank damage gear may normally sit on Kimberly, while Code 64 day gives you a reason to prioritize Tesla instead.

How to Use Your Five Daily Attempts

Do not treat all five attacks as identical repeats. Since ranking depends on your best single attempt, each run can be used to test an improvement.

1. Attempt 1: Establish a baseline with your normal matching-type squad.
2. Attempt 2: Adjust hero selection or formation if you have a plausible improvement.
3. Attempt 3: Test upgraded gear, Drone setup, or another offensive change.
4. Attempt 4: Repeat the strongest setup if earlier damage varied.
5. Attempt 5: Use your finalized formation for another chance at a personal record.

You do not need to change something after every battle if your lineup is already optimized. The important point is to avoid burning all five attempts without checking the damage record between attacks.

Wanted Boss Rewards

Wanted Boss provides three main reward paths. Ranking rewards depend on your best damage result, individual participation milestones are tied to attacking the boss 1, 3, and 5 times, and Goal rewards track specific single-hit damage milestones.

Reward Type	Requirement
Participation Rewards	Reach the daily attack milestones, including 1, 3, and 5 challenges
Ranking Rewards	Improve your highest single-attempt damage and leaderboard position
Goal Rewards	Reach specified best single-hit damage milestones

Available rewards can include progression resources such as Diamonds, speedups, Hero EXP, recruitment-related items, gear materials, and other resources. Exact reward contents and ranking tiers can change with progression or game updates.

Wanted Boss Goal Rewards

The Goal section differs from the ordinary daily attack milestones. Goals are tied to your highest damage from one attack and can progress across repeated appearances of the same Wanted monster rather than requiring you to complete every threshold in a single day. This makes the Goals a useful long-term measure of account progression. A threshold that is impossible today may become achievable after hero upgrades, stronger gear, Exclusive Weapons, Drone development, or later seasonal progression.

How to Increase Wanted Boss Damage

1. Fix the Hero Type First

Before spending resources, confirm that you are using the boss’s 50% weakness. Upgrading the wrong formation does not solve the fundamental matchup problem.

2. Invest in the Main Carry

Kimberly, Tesla, and DVA are natural heroes to review first for Tank, Missile, and Aircraft boss days respectively. Your exact priorities can differ if another hero is considerably more developed.

3. Shift Toward Offensive Gear

Defensive attributes have lower value in a timed damage test where the boss is not primarily threatening your formation. Put your best attack-oriented gear on the heroes producing most of the damage.

4. Improve Your Drone

Drone levels, components, Combat Progress, and Skill Chips can all contribute to stronger formations. Match type-dependent Drone Skill Chips to the squad being used where applicable.

5. Upgrade Hero Center Buildings

Tank Center, Aircraft Center, and Missile Center development increases the corresponding hero type’s combat statistics, making these buildings relevant to their matching Wanted Boss days.

6. Compare Battle Records

Do not judge a formation only by displayed squad power. Run an attempt, record the result, change one meaningful element, and compare again. The setup producing the better actual Wanted Boss damage is the one that matters.

Best Daily Wanted Boss Routine

1. Check which boss is active. Identify whether the day requires Tank, Missile, or Aircraft heroes.
2. Choose a convenient spawn window. Bosses appear at four server-time intervals.
3. Equip your matching squad. Move offensive gear if necessary.
4. Check Drone and hero setup. Make sure the correct formation is selected before attacking.
5. Complete the first attack. Use it as your damage baseline.
6. Review the result. Adjust only where you have a realistic improvement.
7. Reach the 1, 3, and 5 attack milestones. Do not leave easy participation rewards unclaimed.
8. Check Goal progress. Claim any new single-hit milestones you reached.
9. Review your ranking. Decide whether further optimization is worth the effort for your current server competition.

Common Wanted Boss Mistakes

• Using the wrong hero type: This sacrifices the boss-specific 50% damage advantage.
• Sending one squad every day: Code 39, 64, and 87 are intentionally designed around different formations.
• Focusing on defense: Wanted Boss rewards damage output rather than normal frontline survival.
• Using all attempts immediately: Check your damage after each run so you can improve the next one.
• Ignoring secondary squads: Maintaining useful heroes in all three vehicle types improves weekly Wanted Boss performance.
• Forgetting equipment changes: Your strongest offensive gear may be sitting on heroes that do not receive the day’s weakness bonus.
• Looking only at total power: Boss damage is a better test of your actual formation for this event.
• Missing participation milestones: Even players who cannot rank highly can still collect rewards for completing their attacks.
• Ignoring long-term Goals: New progression can push your best single hit past thresholds you previously could not reach.

Optional Faster Starting Point

Players who prefer starting with stronger formations across multiple hero types can browse Last War accounts for sale on Heaven Guardian. When comparing accounts, check the Tank, Aircraft, and Missile rosters, hero stars, gear, Drone progression, server stage, and unlocked seasonal systems rather than judging the account only by its displayed power.

Should I build three squads just for Wanted Boss?

You do not need three equally developed squads immediately, but having usable Tank, Aircraft, and Missile formations becomes increasingly valuable. Develop your primary team first, then gradually improve the other types so you can exploit all three Wanted Boss weaknesses.

Conclusion

The Last War Wanted Boss rewards specialization more than raw displayed power. Code 87 favors Tanks, Code 64 favors Missile Vehicles, and Code 39 favors Aircraft, with the matching hero type receiving a major 50% damage advantage. Start by using the correct formation, concentrate offensive equipment and development on your main damage dealers, and use the five daily attempts intelligently instead of repeating the same setup without checking results. Even if you are not competing for the top rankings, the attack milestones and long-term damage Goals make consistent participation worthwhile.
