Mastering Refugees in Last Z: Survival Shooter

Updated October 12, 2026

Maximizing Your Refugee Strategy in Last Z

Refugees are specialized units in Last Z that provide crucial long-term benefits to your account. Understanding their roles and prioritizing their development is key to sustained progress. This guide will walk you through effective recruitment, assignment, and upgrade strategies.

What Are Refugees?

Refugees are long-term specialists that enhance specific structures and game systems. When deciding which to empower first, their enduring value to your account, rather than just their rarity, is the most important factor. They offer daily advantages, making your base and operations more efficient.

You acquire these specialists at the Club using Refugee Tickets. Once recruited, assign them via the Dispatch panel or the Talent Hub. Enhancements to their bonuses come from Promotions, which require Refugee Fragments.

Top Refugee Priorities

Most refugee value stems from ongoing account efficiency rather than narrow, situational advantages. Therefore, initial focus typically lies with diplomats and other utility-focused refugees before considering more specialized roles.

Prioritization Tiers

This list, validated by players, emphasizes long-term benefits like help capabilities, research, construction, and training acceleration.

  • Tier 1: Diplomats
  • Tier 2: Officers, Nurses, Scientists, Butlers
  • Tier 3: Rider / Assaulter / Shooter Instructors
  • Tier 4: Metallurgists

Early Recruitment vs. Upgrade Focus

While certain S-grade refugees like Butlers and Scientists offer significant early boosts to construction and research, Diplomats generally represent a more valuable long-term upgrade priority due to their compounding benefits.

  • Construction Delays? Recruit an S-grade Butler for your Villa.
  • Research Slowdown? Acquire an S-grade Scientist for your Bookstore.
  • Alliance Support is Regular? Prioritize Diplomat upgrades to enhance help cap and duration bonuses.

An upgraded Butler also provides a small amount of free construction time, but its primary value comes from raw construction speed.

Refugee Ticket Spending Strategy

A common error is overspending tickets prematurely. For most players, using 500-ticket summons with free refreshes offers better control over time. Deeper spending (2000 or 5000 tickets) is typically reserved for genuinely top-tier targets.

  • Default Plan: Use 500 tickets for a summon, then utilize the free refresh to see new options.
  • High-Tier Targets: Only commit 2000 or 5000 tickets when a truly exceptional refugee is available.
  • Cost Scaling: The price increases from 500 to 2000 and 5000 tickets if you repeatedly attempt to summon from the same pool. Establish your budget and adhere to it.
  • Automatic Refresh: The available refugee pool automatically resets every 12 hours. Recruiting also grants a free refresh.

Why Diplomats Are Essential

Diplomats are often the highest-priority refugee because alliance support benefits accumulate across various daily activities, including construction, research, and healing. This makes them one of the most potent long-term efficiency enhancements in the entire refugee roster.

Assigned to the Alliance Center, Diplomats boost the alliance help cap. In-game information also indicates they improve help duration. This combination dramatically speeds up construction, research, and healing processes through allied assistance. Their bonuses scale with their rarity.

For example, 16 hours of allied help time can allow healing approximately 1,300 troops in a single minute.

Refugee Roles and Building Assignments

Understanding each refugee's role is crucial, as the best choice depends on where your account faces bottlenecks. Some refugees enhance universal daily systems, while others are more specialized and should be considered later.

Obtaining Refugee Tickets

Ticket acquisition is limited, highlighting the importance of spending discipline. An effective refugee strategy relies as much on consistent ticket sourcing as it does on target selection.

  • Fury Lord Rewards: A consistent source of tickets.
  • Glory Shop: Offers 5,000 tickets weekly when available.
  • Packs: Available as optional purchases.

Optimal Spending Times for Refugee Tickets

Timing your summons can be advantageous, especially with events like Alliance Duel. Ideally, you want both a strong target selection and an event window that doesn't force a suboptimal decision.

The Alliance Duel's Shelter Upgrade day often includes points for recruiting refugees. Aligning your summons with this day can boost your score. However, if an exceptional refugee appears, many suggest acquiring them immediately regardless of event timing.

Quick Tips

  • Prioritize Diplomats: They offer the best long-term, compounding value.
  • Default to 500 Tickets: Use the 500-ticket summon plus free refresh unless an S-grade Diplomat, Butler, or Scientist appears.
  • Time Summons with Alliance Duel: If possible, recruit during the Shelter Upgrade day for extra points.
  • Assess Needs: Recruit Butlers for construction speed and Scientists for research speed early on if those are your bottlenecks.
  • Ticket Sources: Regularly check Fury Lord rewards and the Glory Shop for tickets.
  • Protect Resources: Before pursuing marginal refugee upgrades, ensure your base defenses and essential resources are secure, especially under server pressure.
