Last War City Clash Season 4 Guide: Copper, Cities and Territory Strategy

City Clash in Last War Season 4: Evernight Isle is the alliance territory system that controls City ownership, Copper production, Digging Strongholds, and access toward the central Level 7 objective. Alliances rebuild their territory from scratch, beginning with a Level 1 Digging Stronghold before advancing through increasingly valuable Cities.

Season 4 adds one major twist: capturing a City gives you its Copper production immediately, but its alliance buff remains locked until your alliance defeats that City’s Oni General during Blood Night Descend. This connects City Clash directly with Blood Night and makes holding territory only the first half of the job.

How Season 4 City Clash Works

The basic Season 4 territory path is:

1. Capture a Level 1 Digging Stronghold.
2. Expand through connected Strongholds and Cities.
3. Reach an unlocked City with adjacent alliance territory.
4. Have an eligible R4 or R5 declare war.
5. Defeat defenders and reduce the City’s Durability to zero.
6. Begin earning Copper from the City.
7. Defeat its Oni General during Blood Night to activate the City buff.
8. Continue toward higher-level Cities and the central Level 7 objective.

Territories that touch diagonally can count as connected under the Season 4 map rules, so leadership should examine the exact route before spending a daily Stronghold capture unnecessarily.

Season 4 City Unlock Schedule

City levels open gradually through the first four weeks. Each standard unlock begins about 12 hours after reset on the listed season day.

Season Timing	City Level
Week 1, Day 3 + 12 hours	Level 1
Week 1, Day 6 + 12 hours	Level 2
Week 2, Day 3 + 12 hours	Level 3
Week 2, Day 6 + 12 hours	Level 4
Week 3, Day 3 + 12 hours	Level 5
Week 3, Day 6 + 12 hours	Level 6
Week 4, Day 7 + 12 hours	Level 7 / Tenryu Castle

Once a City level has opened, it remains eligible for later capture. You do not have to take every City on its unlock day.

Because server cohorts and later updates can adjust event timing, use the live City Clash countdown as the final scheduling reference.

Season 4 City and Stronghold Limits

Rule	Season 4 Limit
Maximum regular Cities held	6
Maximum Digging Strongholds held	6
Daily City declarations	2
Daily Digging Stronghold captures	2
Active City target	1 at a time

The six-City limit makes long-term planning important. Filling every slot with Level 1 and Level 2 Cities can become inconvenient when stronger Level 5 and Level 6 targets open later.

The Level 7 central objective is handled separately from the six normal City slots under the current Season 4 system.

Digging Strongholds Explained

Digging Strongholds are the connectors that let your alliance expand across Evernight Isle. They also produce Stone, one of the main Season 4 building resources.

Stronghold Level	Stone per Hour
Level 1	100
Level 2	120
Level 3	140
Level 4	160
Level 5	180
Level 6	200

Stronghold Stone needs to be claimed through the Alliance City interface, so leadership should remind members to collect it regularly.

Digging Stronghold Guardians

Season 4 Strongholds are protected by Oni enemies such as Oni Samurai, Oni Dōji, and Oni Tengu. Stronger Strongholds have harder guardians.

Inspect the enemy formation before launching rallies and use the normal Tank, Aircraft, and Missile counter system where applicable. Do not assume the squad with the largest displayed Power is automatically the most efficient choice.

Virus Resistance and Rally Leadership

Virus Resistance is one of the most important Season 4 combat requirements. It is raised primarily through seasonal progression such as the Optoelectronic Lab and Lighthouse system.

Season 4 also has an important rally mechanic: the rally leader’s Virus Resistance can raise lower-resistance participants to the leader’s effective resistance level. Members who already have higher resistance keep their own higher value.

This means the best rally leader for an early Digging Stronghold may be your highest-resistance member rather than your absolute highest-Power player.

Season 4 City Capture Rules

Once alliance territory connects to an unlocked City, an eligible R4 or R5 can declare war.

The important rules are:

• Only one City can be actively targeted by the alliance at a time.
• Up to two City declarations can be made per day.
• Your first territory route must begin with a Level 1 Digging Stronghold if the alliance owns nothing.
• Virus Resistance affects siege performance.
• City siege combat can cause part of your troops to die directly.
• The exact direct-death ratio is shown on the City.
• Successful capture starts a protection period.
• Changing ownership normally creates roughly six days of City protection.
• Abandoning a City does not reset its existing protection timer.
• Your own alliance can face roughly a five-day wait before re-declaring on a City it abandoned.

How to Capture a City Efficiently

1. Prepare the Route Before Unlock

R4 and R5 should already know which Digging Strongholds lead to the next City before its countdown reaches zero.

Using one of your two daily Stronghold captures on territory that leads nowhere can delay a Level 5 or Level 6 route by an entire day.

2. Move the Alliance Early

Short march times mean more durability attacks. Relocate active members before declaration instead of asking everyone to move after the siege starts.

3. Check Virus Resistance

A strong squad can still perform poorly when its seasonal resistance is far below the target’s requirements. Make sure your main rally leaders and a reasonable portion of the alliance are ready for the next City level.

4. Clear Defenders First

If another alliance holds the City, concentrate your strongest appropriate squads on removing the defensive formations and reinforcements.

5. Switch to Durability Damage

Once the defensive squads are gone, the priority changes. Get as many marches hitting City Durability as possible.

Waiting for unnecessary long rallies slows the capture when ordinary attacks can already reach the structure.

Copper Production by City Level

Owned Cities continuously generate Copper, Season 4’s major alliance ranking and warfare resource.

City Level	Copper per Hour
Level 1	100
Level 2	200
Level 3	300
Level 4	400
Level 5	500
Level 6	600

Because production is hourly, early ownership matters. A City captured immediately after its unlock generates more total Copper than the same City captured several days later.

Higher levels remain increasingly attractive, so leadership needs to balance early income against keeping City slots available for stronger territory later.

City Buffs Do Not Activate Immediately

This is the major Season 4 City Clash change.

Capturing a City immediately gives your alliance its Copper production, but the City’s alliance buff remains inactive until its Oni General is defeated.

How Oni Generals Work

Oni Generals:

• Appear on Cities your alliance already owns.
• Spawn during Blood Night Descend.
• Can only be attacked by the alliance controlling that City.
• Require rallies because they are significantly stronger than routine world enemies.
• Retain damage between Blood Night appearances if not killed immediately.
• Activate the City’s buff after defeat.

Because damage persists, an alliance that cannot finish a difficult Oni General in one Blood Night can continue during the next appearance without losing all previous progress.

Do Not Capture More Cities Than You Can Activate

An alliance can technically expand quickly, but several newly captured Cities can create a backlog of Oni Generals.

If your roster struggles to defeat those bosses, you will receive Copper but leave useful City buffs inactive. Include Oni General strength in your target selection instead of considering only map position.

City Clash and Blood Night Descend

Blood Night is therefore directly connected to territory progression.

During Blood Night, the alliance should prioritize:

1. Owned Cities whose buffs are still locked.
2. Oni Generals attached to the most valuable City buffs.
3. Strong rally leaders and main squads.
4. Finishing previously damaged Oni Generals where possible.

Do not let players spend the entire Blood Night only farming ordinary enemies while important owned City buffs remain locked.

City Capture Rewards

The first capture of a City provides several layers of rewards.

Alliance members receive general City rewards, while players who directly participate receive additional participation rewards. Alliances also earn Loot Chests that eligible leadership can distribute.

Where practical, have members land at least one durability attack during a first capture so they qualify for participation rewards rather than simply watching from the hive.

Season 4 also ranks durability contribution for additional rewards, so positioning close to the target helps active players complete more attacks before the City falls.

Best Six-City Strategy

You cannot simply keep every City you capture. A good Season 4 map plan evolves as new levels unlock.

Week 1: Build the Route

Use Level 1 and Level 2 Cities primarily to establish territorial access and begin Copper production.

Week 2: Improve Economy and Position

Replace weak or poorly positioned territory when Level 3 and Level 4 Cities provide better routes or alliance bonuses.

Week 3: Prioritize Level 5 and Level 6

Level 6 Cities produce 600 Copper per hour, and only four exist around the central part of the standard map. Competition for those locations can become much more serious.

Begin connecting toward the desired Level 6 City before Week 3 Day 6 rather than trying to build the entire route after it opens.

Week 4: Prepare for Tenryu Castle

The Level 7 Tenryu Castle becomes available at the end of Week 4. Territory adjacent to the central objective is important for participation in the Capitol-style battle.

Do not arrive at Week 4 with six Cities that produce Copper but leave your alliance with no practical route toward the center.

No Cross-Warzone City Captures in Season 4

Season 4 differs from seasons where alliances can fight directly for foreign Cities.

Cities and Digging Strongholds are contested only inside your own Warzone. Alliances from other Warzones do not invade your map to steal those locations.

Cross-Warzone competition instead moves into the Copper War system beginning in Week 4.

This creates an opportunity for Warzone diplomacy. Alliances can coordinate internal City ownership and avoid unnecessary local wars before the larger faction conflict begins.

How City Clash Connects to Copper War

City Clash builds the Copper economy that later becomes important during Copper War.

From Week 4 onward, alliances from the opposing Season 4 factions fight around Alliance Centers rather than capturing each other’s Cities directly. Successful attacks can take Copper from the defending alliance.

This gives City ownership two purposes:

• Generate Copper for seasonal ranking.
• Build the resource stockpile that later needs to be protected during Copper Wars.

Avoid unnecessary intra-Warzone troop losses if your Warzone intends to compete seriously once the faction battles begin.

Season 4 City Clash vs Season 3

Mechanic	Season 3	Season 4
Main City Resource	Spice	Copper
Stronghold Resource	Mithril	Stone
Season Resistance	Curse Resistance	Virus Resistance
Max Cities	8	6
Max Strongholds	8	6
City Buff Activation	Available through normal ownership rules	Requires defeating the City’s Oni General
Main Cross-Warzone Conflict	Spice-focused warfare	Copper War against Alliance Centers

The lower City and Stronghold limits make Season 4 route planning less forgiving, while Oni Generals add another combat requirement after each capture.

Best R4 and R5 City Clash Strategy

1. Choose the intended Level 6 route early. Work backward from the central territory.
2. Use only necessary Strongholds. You have six slots and two captures per day.
3. Capture Cities soon after unlock. Earlier ownership means more Copper generated.
4. Track the six-City cap. Leave room for better Week 2 and Week 3 targets.
5. Check Virus Resistance. Do not schedule a target most of the alliance cannot fight effectively.
6. Prepare Oni General rallies. City buffs require follow-up combat during Blood Night.
7. Coordinate internally with the Warzone. Foreign alliances cannot take these Cities, so unnecessary local wars can be avoided.
8. Preserve troops for Copper War. Season 4’s larger faction conflict begins in Week 4.

Common Season 4 City Clash Mistakes

• Filling all six City slots during Week 1: Better Cities unlock later.
• Capturing Strongholds without a route: Each alliance gets only two new captures per day.
• Ignoring Virus Resistance: Seasonal combat performance depends on more than Power.
• Using the wrong rally leader: High Virus Resistance can benefit lower-resistance participants.
• Forgetting to claim Stronghold Stone: The resource needs regular collection.
• Assuming a captured City buff is active: You must defeat its Oni General.
• Skipping Blood Night after City captures: This can leave several important buffs locked.
• Waiting too long to take valuable Cities: Every missed hour reduces Copper production.
• Dropping Cities casually: Protection and re-declaration cooldowns can complicate your route.
• Planning foreign City invasions: Season 4 does not use cross-Warzone City captures.
• Arriving at Week 4 with depleted troops: Copper War adds another major alliance combat demand.

Optional Faster Starting Point

Season 4 City Clash rewards developed heroes, strong troop tiers, good research, Drone progression, and enough seasonal development to raise Virus Resistance quickly. Players who prefer starting from an established position can browse Last War accounts for sale on Heaven Guardian. When comparing Season 4 accounts, check hero formations, troop tier, Virus Resistance, Optoelectronic Lab progress, Tactics Cards, server timing, and alliance position rather than relying only on total Power.

Conclusion

Last War City Clash Season 4 combines traditional territory expansion with Copper production and Blood Night progression. Build from Level 1 Digging Strongholds, keep enough territory slots available for later targets, and capture valuable Cities as early as practical so they generate more Copper over the season.

The biggest Season 4 difference comes after the capture. Every important City also brings an Oni General that must be defeated during Blood Night before its alliance buff becomes active. Coordinate territory planning, Virus Resistance, Blood Night rallies, and Copper War preparation together instead of treating them as separate events.
