Last Z: Survival Shooter – Optimize Lucky Discounter Purchases

Updated October 12, 2026

Master Last Z's Lucky Discounter Event

The Lucky Discounter is a recurring event in Last Z where players can acquire valuable items at reduced prices. By understanding its mechanics and planning ahead, commanders can significantly boost their base progression, especially through long-term investments like badges.

What is the Lucky Discounter?

This event allows you to use event tickets to refresh shop offers, revealing various discounted items. The most strategic approach involves focusing on specific discount checkpoints rather than purchasing every single offer. Badges are often the primary target, as they contribute to essential research and development within your alliance.

Event Cycle

To effectively prepare for the Lucky Discounter, it's crucial to know its place in the game's event rotation. It consistently follows a pattern:

Gacha Go → Bullseye → Lucky Discounter → Lucky Chest

Anticipating this sequence helps you accumulate tickets and diamonds in advance, ensuring you're ready to seize the best opportunities when the event arrives.

Guaranteed 90% Discount Milestones

The most valuable aspect of the Lucky Discounter is its fixed 90% discount attempts. These predictable, high-value offers transform the event into a prime opportunity for resource acquisition.

AttemptDiscountTickets Needed
5th90% guaranteed4 tickets + 1 free
9th90% guaranteed8 tickets + 1 free
18th90% guaranteed17 tickets + 1 free
32nd90% guaranteed31 tickets + 1 free

Strategic approach: Accumulate enough tickets to reach at least the 9th attempt. Remember that each draw refreshes the available shop items. Always check the inventory before committing diamonds; if the items don't align with your current objectives, hold onto your resources.

Item Prioritization by Discount Level

Not all discounts are created equal. Focus your spending on the highest value offers.

DiscountBadgesSpeedupsOther Items
90%PURCHASE FIRST (if needed)BUY only if essentialAVOID unless they support immediate goals
70%CONSIDER with ample diamondsSKIP; await 90%AVOID unless they support immediate goals
50%CONSIDER with ample diamondsSKIPSKIP
30%SKIPSKIPSKIP
10%SKIPSKIPSKIP

The primary rule: always prioritize 90% offers for speedups. Badges may be considered at 50% or 70% if your diamond supply is secure; otherwise, it's best to wait for a better deal.

Value Comparison: Lucky Discounter vs. VIP Store

The Lucky Discounter often provides superior value compared to regular in-game shops.

Badges

  • VIP Store: 100 badges for 150 diamonds (1.5 diamonds per badge)
  • Lucky Discounter (90%): 2,000 badges for 600 diamonds (0.3 diamonds per badge)
  • Result: A 5x better value at the 90% discount tier.

Speedups

  • VIP Store: Approximately 32 hours for 1,700 diamonds
  • Lucky Discounter (50%): 15 hours for 900 diamonds (comparable to VIP)
  • Lucky Discounter (90%): 25 hours for 900 diamonds (significantly better)

Conclusion: Only speedups at 90% discount surpass VIP store value. However, badges purchased through Lucky Discounter are almost always a better deal at 50% or more.

Ticket Management Strategy

Saving tickets for bulk use, rather than spending them as they arrive, offers greater predictability and value. Tickets do not expire and carry over between events.

Recommended Ticket Targets

  1. First Goal: 9th Draw (8 tickets)
    • Guarantees 90% price reductions on the 5th and 9th attempts.
    • Achievable with 8 of the 16 free tickets typically provided in one event, plus the initial free draw.
    • Any remaining free tickets can be saved for future events.
  2. Next Goal: 18th Draw (17 tickets)
    • Adds a third guaranteed 90% offer.
    • Requires one additional ticket beyond the 16 free ones from a single event. Saved tickets from previous runs can help reach this.
  3. Advanced Goal: 32nd Draw (31 tickets)
    • Accesses all four fixed 90% discounts through the 32nd attempt.
    • Demands 15 extra tickets beyond the 16 free ones per event. Saving across multiple events is key here.

Ticket Supply: The first draw is free. An event typically provides 2 free tickets from its dedicated shop and 2 from daily rewards over 7 days, totaling 16 free tickets. This equates to 17 draws including the initial free one.

Why Badges Are the Top Purchase

Badges are generally the most impactful purchase in Lucky Discounter because they fuel Alliance Recognition research. This research provides long-term advantages instead of short-term conveniences.

Alliance Recognition research grants:

  • Increased medal production (for hero upgrades)
  • Faster hero training
  • Alliance-wide buffs and bonuses
  • Crucial late-game power multipliers

Achieving 50,000 to 100,000+ badges is essential to fully develop Alliance Recognition. Lucky Discounter offers one of the most efficient free-to-play avenues for accumulating these. Strategically using badges during specific in-game events can further amplify their value.

Real-World Spending Example

An example of a 32-attempt run showcases potential outcomes. This is illustrative, not a guarantee:

  • Diamonds spent: 30,700
  • Badges obtained: 42,000
  • Building speedups: ~210 hours
  • Research speedups: Substantial quantity

To put this in perspective, 42,000 badges alone would cost 63,000 diamonds at the standard VIP store rate (1.5 per badge). Since speedups were also acquired, this example demonstrates the event's overall efficiency.

Quick Tips

  • Target 90% offers: Focus your efforts on the 5th, 9th, 18th, and 32nd attempts for maximum value.
  • Save tickets: Unused tickets carry over; save them for larger runs across multiple events.
  • Prioritize badges: Badges offer long-term progression benefits through Alliance Recognition research.
  • Mind your diamonds: Only spend if the offer aligns with your goals and doesn't jeopardize your overall diamond reserve.
  • Skip low discounts: Avoid 10% and 30% offers; they rarely provide good value.
  • Check the shop: The 90% discount is guaranteed, but the items in the shop are random; always verify if they are what you need.
  • Event cycle awareness: Plan your resource accumulation around the Gacha Go → Bullseye → Lucky Discounter → Lucky Chest rotation.
