Last Z Alliance Duel Guide: Schedule, Strategy, and Daily Priorities

Alliance Duel, commonly called VS in Last Z, is a recurring alliance competition built around six themed scoring days. Each day rewards a different type of progression, such as vehicle upgrades, construction, research, heroes, troop training, or PvP.

The main Alliance Duel strategy is simple: save resources throughout the week and use them on the day that rewards them. Construction speed-ups are more valuable when Shelter Upgrade is active, Research Badges belong on Age of Science, and hero materials should normally wait for Hero Initiative. Good timing lets you improve your account while earning personal chests and helping your alliance win the matchup.

How Alliance Duel Works

Alliance Duel matches your alliance against another alliance for a multi-day competition. Members earn personal points by completing the activities listed under the current VS theme, while those points also contribute to the alliance’s overall score.

Personal progress unlocks reward chests during each scoring day. At the alliance level, coordination matters because winning individual days and building a strong weekly total depends on many members contributing efficiently rather than a few players spending everything.

The event normally follows six themed days:

Day	Theme	Main Focus
Day 1	Modded Vehicle Boost	Vehicle upgrades, vehicle materials, Radar activities
Day 2	Shelter Upgrade	Construction, building power, Bounty Missions, refugees
Day 3	Age of Science	Research, Research Badges, research speed-ups, trade activities
Day 4	Hero Initiative	Hero fragments, recruitment, equipment and hero development
Day 5	Holistic Growth	Troop training, promotion, speed-ups and related development
Day 6	Enemy Buster	PvP combat and selected combat-related activities

The calendar day associated with each phase can appear differently depending on server reset and local timezone. Use the in-game VS > Today’s Theme screen as the final authority before using saved resources.

Prepare for Alliance Duel Before the Week Starts

Most Alliance Duel points are prepared before the scoring day begins. A player who saves for several days can often contribute more efficiently than someone who spends resources continuously.

Resources Worth Saving

• Golden Wrenches and other vehicle development materials
• Vehicle component and chip chests
• Construction speed-ups
• Bounty refresh items
• Research speed-ups
• Research Badges
• Intercity trade refreshes
• Hero fragments
• Recruitment tickets
• Hero equipment materials
• Training speed-ups
• Radar tasks when they can be held safely for the next scoring period

You do not need to stop normal account progression completely. Keep necessary queues running and complete urgent upgrades. The goal is to delay flexible spending that can be moved to a more rewarding day without harming your account.

Day 1: Modded Vehicle Boost

The first phase focuses primarily on your Modded Vehicle. This is the day to use vehicle resources you have accumulated since the previous Duel.

Typical scoring activities can include:

• Using Golden Wrenches
• Using Modification Blueprints
• Opening vehicle component boxes
• Opening vehicle chip chests
• Completing eligible Radar activities
• Participating in relevant Boomer rallies

Pay particular attention to the wording on the event screen. Some vehicle tasks award points for opening a component or chip box rather than simply consuming the component afterward.

Day 1 Strategy

Avoid opening saved vehicle boxes casually during the rest of the week. Hold them until the Vehicle phase and combine them with other eligible activities. Radar tasks can also be useful, but only save them when doing so will not cause tasks to cap or expire.

Day 2: Shelter Upgrade

Shelter Upgrade is construction day. Save construction speed-ups and plan important building upgrades so that a significant portion of their progress can contribute to this phase.

Depending on the current scoring list, Day 2 can reward:

• Increasing building or Structure Power
• Using construction speed-ups
• Completing high-quality Bounty Missions
• Recruiting refugees
• Using certain equipment-development materials listed in the live event

Plan Major Construction in Advance

You do not necessarily need to begin a long Headquarters upgrade after Day 2 starts. If an important upgrade takes a long time, you can begin it earlier and plan its completion or acceleration around Shelter Upgrade.

This keeps your construction queue productive while still allowing saved speed-ups to generate event points.

Save Bounty Refreshes

Higher-quality Bounty Missions can provide useful Day 2 points, making refresh items more valuable during this phase than when used randomly throughout the week. Use refreshes selectively and prioritize valuable missions shown on your current event screen.

Day 3: Age of Science

Age of Science is research day and one of the most important phases for long-term players because Research Badges, research speed-ups, and important Laboratory upgrades can all be aligned with Alliance Duel scoring.

Common scoring sources include:

• Research progress
• Research speed-ups
• Consuming Research Badges
• Eligible Intercity Trade activities

Save Research Badges for Day 3

Research Badges are difficult enough to accumulate that using them without event value is usually inefficient. When possible, prepare a useful Badge-heavy research node and complete or accelerate it during Age of Science.

Alliance Recognition is especially relevant because it directly improves your future Alliance Duel progression and rewards.

Day 4: Hero Initiative

Hero Initiative is the time to use many of the hero resources you have saved during the week. It is often easier to prepare for than construction or research because fragments and recruitment items can simply remain in your inventory until the correct phase.

Eligible activities commonly include:

• Using hero fragments
• Primary recruitment
• Using relevant recruitment tickets
• Upgrading orange hero equipment
• Using Power Cores
• Using eligible exclusive equipment materials
• Using skill materials listed by the current task

Specific hero actions can change between event versions. For example, one scoring list may reward an action that another version does not. Check the live Hero Initiative task before using a large amount of Hero EXP or other materials.

Upgrade Heroes You Actually Use

Alliance Duel should support your account rather than encourage useless upgrades. Concentrate expensive hero and equipment resources on your primary formation whenever possible instead of upgrading weak heroes purely for points.

Day 5: Holistic Growth

Holistic Growth is strongly associated with troop development. This is where your saved training speed-ups become especially useful.

Typical scoring activities include:

• Training troops
• Promoting troops
• Using training speed-ups
• Using other eligible speed-ups shown by the live task
• Completing Radar activities

You can continue normal troop training throughout the week so your training buildings do not sit idle. The important distinction is to save the bulk of your training speed-ups for Holistic Growth.

Do Not Train Weak Troops Only for Points

Low-tier troop strategies can sometimes generate event points efficiently, but creating units with no useful role can leave you spending additional resources to promote them later. Unless you have a specific plan, train or promote troops that contribute to your actual army progression.

Day 6: Enemy Buster

Enemy Buster changes the event from stockpiling and upgrading to direct combat. Points primarily come from PvP-related activities and selected missions displayed on the current scoring screen.

Day 6 requires more alliance coordination than the previous phases because poor attacks can cost troops and resources while also giving the opposing side opportunities to score.

Coordinate Before Attacking

• Check alliance announcements before teleporting or attacking.
• Confirm which alliance is your Duel opponent.
• Coordinate targets instead of having several players chase the same shelter.
• Use rallies or organized fights when they reduce unnecessary losses.
• Avoid attacking accounts that clearly outmatch your formations.
• Keep enough resources available for healing and recovery.

Shield If You Are Not Fighting

If you cannot participate during the combat period, shielding is usually much safer than leaving your shelter exposed. Enemy Buster is not the day to remain unprotected with valuable resources and troops at home.

Do not deliberately take inefficient losses simply because your current scoring screen awards points for a combat-related action. Alliance score matters, but protecting your long-term troop strength matters too.

Use Full Preparedness to Double-Dip Your Resources

One of the best Alliance Duel strategies is synchronizing major upgrades with the matching Full Preparedness activity. Players often refer to this overlap as Golden Hour.

Full Preparedness rotates through activity types during the day. When its current activity matches the Alliance Duel theme, the same construction, research, hero, vehicle, or troop upgrade can contribute to both events.

Alignment commonly occurs around Full Preparedness rotations beginning at Apocalypse Time 08:00 or 20:00, but you should verify the current schedule in-game. Server progression and event changes can affect timing.

Example

If Holistic Growth is active in Alliance Duel and Army Expansion is the current Full Preparedness task, using your saved training speed-ups during the overlap can progress both events without increasing the amount of resources consumed.

This is particularly valuable for F2P and low-spending players because it improves rewards through timing rather than additional spending.

Alliance Recognition Research

Alliance Recognition is closely tied to Alliance Duel. Its research can improve event scoring and rewards while unlocking access to additional personal reward chests as the tree develops.

This creates a useful cycle:

1. Participate in Alliance Duel.
2. Earn Badges from personal and alliance rewards.
3. Spend appropriate Badges on Alliance Recognition during Age of Science.
4. Improve future Alliance Duel rewards and scoring efficiency.
5. Repeat the process over future Duel cycles.

Alliance Recognition is not direct combat research, so its priority should still be balanced against military progression. Players who participate actively in Alliance Duel every week gain more value from investing in the tree than players who rarely complete event milestones.

Set a Personal Chest Target Before Spending

A common mistake is assuming you must empty your inventory every Alliance Duel. That can produce a strong score this week while leaving you unable to reach useful milestones the following week.

Instead, examine your current personal chest thresholds and choose a realistic target for each day. Once the next chest would require an unreasonable amount of rare material, consider stopping and carrying the remaining stockpile forward.

This is especially important on Shelter Upgrade and Age of Science, where construction speed-ups, research speed-ups, and Badges can be difficult to replace.

Alliance Duel Strategy for F2P Players

F2P players can contribute effectively without trying to compete with the largest spenders. Resource timing matters more than attempting to win every personal ranking.

• Save materials for their matching Duel day.
• Take advantage of free Radar, Bounty, trade, and recruitment activities.
• Use Full Preparedness overlaps whenever practical.
• Develop Alliance Recognition gradually.
• Set attainable chest targets instead of draining your inventory.
• Save expensive resources if your alliance leadership decides the current matchup is not worth pushing.
• Use Day 6 carefully rather than sacrificing troops recklessly.

Alliance Strategy: Winning as a Group

Alliance Duel is easier when leadership communicates the plan before members begin spending.

Publish the Daily Schedule

Members should know which items belong to each day before the Duel starts. A simple Day 1–6 schedule prevents construction, research, vehicle, and hero materials from being consumed at the wrong time.

Announce Full Preparedness Overlaps

Alliance leadership can remind members when the current Full Preparedness task matches the Duel theme. This improves scores without requiring additional resources.

Decide When to Push or Save

Not every matchup needs maximum spending. If the score gap becomes unrealistic, leadership may decide to preserve resources for a future week rather than exhaust everyone’s inventory pursuing an unlikely daily result.

Organize Enemy Buster

Day 6 benefits from clear combat instructions. Strong fighters can take offensive roles, while weaker or unavailable members can shield and avoid becoming easy targets.

Common Alliance Duel Mistakes

Using Resources on the Wrong Day

This is the most preventable mistake. A speed-up used today may provide account progress, but waiting until its matching theme could provide account progress plus Duel rewards.

Ignoring the Live Task List

Guides provide a planning framework, but event scoring can change. Always verify the current VS task before spending a large stockpile.

Chasing Every Chest

The next milestone is not automatically worth reaching. Consider how many rare resources it requires and what those resources could accomplish next week.

Missing Full Preparedness Alignment

Spending outside the matching Full Preparedness window can mean giving up extra rewards from resources you were already going to use.

Upgrading Things You Do Not Need

Do not build useless troops, upgrade irrelevant heroes, or research low-priority technologies purely because they award Duel points.

Going Into Enemy Buster Unshielded

If you are not actively fighting, an exposed shelter can create unnecessary losses. Plan protection before the combat phase begins.

Optional Spending During Alliance Duel

Alliance Duel can be played effectively without spending. Players who do purchase premium currency or packs should still follow the same save-and-spend schedule rather than buying materials and consuming them immediately.

If you already intend to purchase Gold Bars or eligible in-game items for an upcoming Duel, you can review the available Last Z top-up options through Heaven Guardian. Decide what your account actually needs before purchasing, and align usable resources with the correct scoring phase whenever possible.

Follow your alliance’s combat plan and avoid attacking stronger opponents unnecessarily. If you will be offline or cannot participate safely, use protection rather than leaving your shelter exposed.

Should I spend everything every week?

No. Set a realistic personal chest target for each day. If the next milestone requires too many rare materials, saving those resources for another Duel can provide better long-term value.

Can F2P players score well in Alliance Duel?

Yes. F2P players benefit significantly from saving resources, matching them to the correct theme, using free scoring activities, synchronizing with Full Preparedness, and avoiding inefficient pushes for unreachable milestones.

Conclusion

Alliance Duel rewards preparation more than impulsive spending. Learn the six-day rotation, save each resource for its matching theme, synchronize major upgrades with Full Preparedness, and build Alliance Recognition over time. On Enemy Buster day, replace individual rushing with alliance coordination and protect your shelter whenever you are unable to fight.

The most efficient player is not necessarily the one who spends the most resources in one week, but the one who repeatedly turns normal account progression into event rewards. For more event strategies, progression advice, and gameplay tips, explore our additional Last Z guides.
