The Rampage Boss event in Last War is a server-wide PvE challenge where three powerful bosses awaken around the Capitol during the same day. Every Commander attacks individually, but all damage contributes toward the shared boss HP pool. Your personal damage also matters because the event has an individual ranking covering all three bosses.
Rampage Boss normally runs every two weeks on Sunday. The three bosses awaken at 00:00, 06:00, and 12:00 server time, and Commanders with Base Level 8 or higher can attack each boss up to three times. Each boss is weak to a different hero type, so preparing Tank, Aircraft, and Missile squads is the key to maximizing your nine possible attacks.
Attack soon after each boss awakens, use all three available attempts, and match the boss weakness: the first boss favors Tanks, the second favors Aircraft, and the third favors Missile heroes. If the server reduces a boss to zero HP, return to the event and use the Eliminate option for the additional reward opportunity.
How the Rampage Boss Event Works
Three mysterious boss locations surround the Capitol. During Rampage Boss day, these bosses awaken one after another and become available for the entire server to attack.
| Rampage Boss Rule | Current Format |
|---|---|
| Event Frequency | Approximately every two weeks |
| Event Day | Sunday |
| Boss Spawns | 00:00, 06:00 and 12:00 server time |
| Minimum Base Level | Level 8 |
| Attacks Per Boss | 3 |
| Total Possible Attacks | 9 across all three bosses |
| Attack Type | Individual attacks; no rally required |
| Ranking | Cumulative personal damage across the three bosses |
Rampage Boss Weaknesses
Each of the three bosses has a different hero-type weakness. The exact monster names and models can vary with your server’s seasonal progression, but the important part is the trait shown on the active boss screen. For example, Season 2 versions have included the Mutated Bear, Mutated Mammoth, and Mutant Gorilla.| Boss Order | Spawn Time | Weakness | Recommended Squad |
|---|---|---|---|
| First Boss | 00:00 | Tank Heroes | Tank formation |
| Second Boss | 06:00 | Aircraft Heroes | Aircraft formation |
| Third Boss | 12:00 | Missile Heroes | Missile formation |
Best Strategy for the Tank-Weak Boss
The first Rampage Boss favors Tank heroes. For many accounts, this is also the easiest boss to optimize because Tank is a common first formation. Useful heroes can include:- Kimberly: high-priority Tank damage dealer.
- Mason: strong PvE-focused option, especially after later progression upgrades.
- Marshall: support that can increase overall squad output.
- Stetmann: additional Tank damage when well developed.
- Williams or Murphy: useful for completing the Tank formation when needed.
Best Strategy for the Aircraft-Weak Boss
The second boss favors Aircraft heroes. Players who focus heavily on Tanks often lose the most damage here because their Aircraft roster may be less developed. Useful Aircraft choices include:- DVA: major Aircraft damage dealer.
- Morrison: another strong offensive option.
- Schuyler: useful damage and utility.
- Carlie: helps complete a full Aircraft formation.
- Lucius: another natural Aircraft squad member.
Best Strategy for the Missile-Weak Boss
The third boss favors Missile Vehicle heroes. This is often the least developed formation on younger accounts, making it another important test of roster depth. Useful Missile heroes include:- Tesla: one of the key Missile damage dealers.
- Fiona: strong offensive option for developed Missile teams.
- Swift: useful additional damage.
- McGregor: can contribute to a Missile-focused setup.
- Adam: useful for completing the formation.
Your first upgrade priority should still be one powerful primary squad. For Rampage Boss specifically, gradually develop enough Tank, Aircraft, and Missile heroes to exploit all three weaknesses rather than expecting one formation to produce optimal damage against every boss.
Why You Should Attack Early
Every Commander has three attacks available against each boss, but those attempts are only useful while the boss can still be attacked normally. On an active server, the combined damage from hundreds of Commanders can reduce a boss’s HP very quickly. Waiting several hours after a spawn may therefore leave you with unused attempts. A practical schedule is:- 00:00 boss: use three Tank-focused attempts as soon as practical.
- 06:00 boss: switch equipment and Drone settings if necessary, then use your Aircraft attempts.
- 12:00 boss: prepare your Missile formation and complete the final three attacks.
How the Eliminate Mechanic Works
When the server collectively removes all of a Rampage Boss’s HP, the boss enters a Vulnerable state. Normal attacks are no longer available at that point. Instead, the event displays an Eliminate option. Using Eliminate on the weakened boss provides an additional reward opportunity, making it important to revisit the event after the HP bar reaches zero.Once the boss reaches zero HP, stop looking for another normal attack. Open the Rampage Boss event and check for the Eliminate command. Players who attack early but never return after the kill can overlook this additional reward step.
How to Increase Rampage Boss Damage
Match the Boss Weakness First
Formation type should be the first thing you check. Optimizing gear on the wrong squad while ignoring a boss’s Tank, Aircraft, or Missile weakness misses the event’s central mechanic.Prioritize Offensive Heroes
Rampage Boss is a damage race. Use your strongest damage-producing heroes within the favored type and build the rest of the formation around increasing total output.Move Your Best Gear
If your best offensive equipment normally sits on your primary formation, consider moving appropriate pieces to the damage dealers you are using for the current boss. You do not need three full sets of equally developed gear to improve all three boss attempts.Check Your Drone Setup
Drone progression applies across important combat content, and type-specific Skill Chips should match the formation you are using when those systems are available.Use Applicable Damage Buffs
Temporary offensive bonuses can improve boss damage when the game allows them. Check which buffs are active on your account before using your limited attacks rather than assuming every temporary combat effect applies automatically. Some players also activate War Fever before attacking for the additional combat bonus.Compare Actual Battle Results
Displayed power does not always identify the best Rampage Boss formation. Use your first attempt as a benchmark, adjust one meaningful element, and compare the next result. If a weaker-looking matching formation consistently produces more damage, use the battle result rather than the power number to guide your final attempt.Position Your Base Near the Capitol
Rampage Bosses appear around the Capitol. Moving your Base closer can shorten the travel time for your attacks, allowing your formation to return sooner. When your Base is far away, the boss march uses a capped travel time of roughly 30 seconds each way. Being close enough can reduce that travel time further. This is especially useful on active servers where bosses disappear quickly. Do not relocate into a dangerous position purely for a few seconds of travel time. Consider your server’s current PvP situation and whether you need to preserve a shield or safe location.Rampage Boss Rewards
The event has several reward layers.
Server Damage and Kill Rewards
The entire server contributes to each boss’s HP reduction. Rewards improve as the server pushes the boss farther and successfully defeats it. Players who participate can receive the applicable damage or completion rewards, with unfinished boss rewards handled through the event’s mail system at the end of the cycle.Eliminate Rewards
After a defeated boss becomes Vulnerable, the Eliminate command provides another reward opportunity. Check every defeated boss rather than assuming the HP reaching zero completes all interaction with it.Top 100 Damage Ranking
Your ranking score combines damage across all three Rampage Bosses. The Top 100 Commanders receive additional ranking rewards after the event. Ranking rewards are now delivered shortly after daily reset under the updated reward-delivery system.Rampage Boss Difficulty Progression
Rampage Boss has a server-wide difficulty progression system. When the server successfully defeats all three bosses during an event, stronger bosses with improved reward pools can appear in the next Rampage Boss cycle.
This means a successful server gradually moves into harder versions rather than permanently fighting the same boss strength.
A July 2026 game update adjusted the maximum Rampage Boss level to 15. Future updates may change this cap again, so servers at the top end should use the live event interface as the final reference.
Rampage Boss vs Wanted Boss
Rampage Boss and Wanted Boss both reward matching the correct hero type, but the events work differently.| Feature | Rampage Boss | Wanted Boss |
|---|---|---|
| Main Format | Server works together against shared boss HP | Individual timed damage challenge |
| Typical Schedule | Biweekly Sunday | Monday through Saturday rotation |
| Bosses | Three in one event day | One code-based boss type per day |
| Attempts | 3 per boss | 5 daily challenges |
| Boss Can Be Defeated | Yes, through combined server damage | Ranking focuses on personal damage |
| Special Mechanic | Vulnerable state and Eliminate | Highest single-attempt damage matters |
Best Rampage Boss Routine
- Check the event before Sunday begins. Confirm the current boss level and available rewards.
- Prepare three formations. Have usable Tank, Aircraft, and Missile setups ready.
- Attack the first boss after 00:00. Use the matching Tank formation.
- Use all three attempts while the boss is still active.
- Return after the boss becomes Vulnerable. Use Eliminate when available.
- Repeat at 06:00 with Aircraft.
- Repeat at 12:00 with Missile.
- Move offensive equipment between squads if helpful.
- Check the cumulative damage ranking. Decide whether further optimization matters for your Top 100 chances.
- Collect all available event rewards.
Common Rampage Boss Mistakes
- Arriving too late: An active server may defeat the boss before you use all three attempts.
- Using one formation against every boss: Each boss favors a different hero type.
- Ignoring the trait screen: Seasonal boss names can change, but the displayed weakness tells you which formation to use.
- Forgetting Eliminate: Revisit defeated bosses once they become Vulnerable.
- Using all your best equipment on an off-type squad: Move offensive gear when another formation needs it.
- Judging only by squad power: Actual boss damage is the better comparison.
- Ignoring secondary hero types: Rampage Boss rewards accounts that eventually develop all three formation categories.
- Missing one spawn entirely: Three unused attacks also mean less cumulative ranking damage.
- Assuming boss strength never changes: Successful servers progress to harder levels, currently capped at Level 15.
