Last Z Refugee System Guide: How to Consistently Get Orange Refugees

 

If you’re still treating refugee pulls in Last Z as pure RNG, you’re burning tickets for no reason. Once you understand the mechanics behind recruitment, pity, and upgrade efficiency, you can actively control your outcomes—and start building a full orange setup much faster.

How the Refugee System Actually Works

Refugees are not just filler units—they’re a core progression system. Assigning them to buildings directly boosts your development speed, whether it’s construction, research, troop training, or alliance assistance. Since each building can host up to four refugees and their effects stack, optimizing this system gives exponential value over time.

Refugees can also be understood as long-term account specialists rather than simple stat boosters. Each one is tied to a specific building or system, and their real value comes from how consistently they improve your daily progression loop. Because of this, choosing who to invest in should be based not just on rarity, but on how often their bonus is applied across your account.

The key mechanic most players misunderstand lies in recruitment. Every refresh shows three refugees, and each pull selects randomly from the remaining pool—not from the entire system. This means you’re making controlled selections within a limited set, not blind pulls.

Cost scaling is also important:

First pick: low cost

Second pick: higher

Third pick: highest

This structure is what enables strategic efficiency.

In addition, some refugees may come with different bonus scaling ranges even within the same rarity tier. This means not all orange refugees are strictly equal in long-term value. While rarity determines upgrade potential, the actual effectiveness depends on how well their bonus aligns with your current progression stage.

 

The Most Efficient Recruitment Strategy

The core loop is simple but highly effective. Each time you refresh, you should evaluate the three available refugees instead of pulling blindly. If there’s no orange option, only take a single low-cost pull to activate the free refresh, then immediately reset the pool. This allows you to cycle through more options while spending the minimum number of tickets.

From a long-term efficiency perspective, most experienced players default to the 500-ticket pull plus free refresh loop. This minimizes risk while maximizing pool cycling. Higher-cost pulls (2000 or 5000) are typically only justified when a top-tier refugee—such as a high-impact utility unit—appears in the pool and is worth securing immediately.

Once an orange refugee appears, your approach should shift. At that point, you’re no longer conserving—you’re securing value. Continue pulling within that same pool until you obtain the orange unit, even if it means paying the higher costs for later picks.

①If you see 1 orange → take it and reset

②If you see 2 oranges → take both

③If you see 3 oranges → take all (best-case scenario)

 

Drop Rates and the Hidden Pity System

The system isn’t pure randomness—it’s structured RNG with safeguards.

Approximate rates:

• Orange: ~6–7%
• Purple: ~20%
• Blue: ~30%+
• Green: ~35–40%

More importantly, there’s a pity mechanic:

• Each recruitment adds progress
• At max stacks, your next refresh guarantees at least one orange in the pool

This means your pulls are always moving toward a guaranteed outcome. If you track your pity properly, you can time your spending for maximum efficiency.

It’s important to note that the pity system guarantees an orange refugee in the pool, not directly in your inventory. You still need to apply the correct pull strategy to actually obtain it, which is why efficient refresh and selection management remains critical even after hitting pity.

 

Resource Management: Tickets vs Diamonds

Recruitment uses tickets first, then automatically fills the gap with diamonds at a 1:1 ratio. That means you’re never locked out—as long as your total resources cover the cost.

Main ticket sources:

1.Weekly shop purchases

2.Daily activity (especially boss content like Fury Lord)

3.Ranking rewards from damage contribution

Additional sources such as weekly shops (like Glory Shop) and event-based rewards can also provide steady ticket income. Because ticket supply is limited, maintaining spending discipline is just as important as targeting the right refugees.

Because tickets and diamonds are interchangeable during recruitment, it’s important to treat them as a combined resource pool rather than separate currencies. Overspending diamonds unintentionally is a common issue, especially during high-cost pulls.

 

Upgrade System Explained

Only purple and orange refugees are worth upgrading, and each unit follows a long-term progression path consisting of five stars, with five upgrade steps per star. The cost increases significantly at higher levels and requires both same-rarity fragments—obtained from duplicates—and green fragments, which are universally needed across all upgrades.

A major inefficiency comes from focusing too heavily on a single refugee. Since each building can host multiple units and their bonuses stack, concentrating resources into one maxed refugee while others remain underdeveloped results in lower overall gains. A more effective approach is to upgrade evenly across all assigned refugees, progressing star by star.

Another long-term consideration is fragment efficiency. Since higher-star upgrades require exponentially more fragments, spreading upgrades early not only improves immediate performance but also reduces the risk of resource bottlenecks later.

 

Upgrade Priority

In the early to mid game, your focus should be on core progression buildings. The alliance center stands out as the most impactful, as it reduces timers through alliance help mechanics. Construction-related buildings come next, followed by research structures, both of which directly accelerate your account growth.

From a role-based perspective, community-tested priorities typically favor utility-driven refugees over niche roles. Diplomats are widely considered the highest-value investment due to their impact on alliance help systems. They are followed by broadly useful roles such as Officers, Scientists, Butlers, and Nurses, all of which contribute to core progression systems like troop capacity, research, construction, and healing.

Diplomats stand out because their value compounds across multiple systems simultaneously. By increasing alliance help capacity and duration, they indirectly accelerate construction, research, and healing, making them one of the strongest long-term efficiency upgrades in the entire refugee pool.

As you transition into mid game, troop training buildings gain importance since they directly affect how quickly you can scale your army. Moving further into late game, the focus shifts toward combat efficiency and sustainability. Military centers become valuable for increasing troop capacity, while hospitals play a critical role in maintaining your forces through faster and more efficient healing.

Resource production refugees, on the other hand, offer relatively low long-term value and are generally not worth prioritizing. It’s also important to remember that the specific identity of a refugee doesn’t matter—their assigned building bonus is what truly defines their usefulness.

It’s also worth adjusting your priorities dynamically based on your current bottleneck. If your progress is limited by build timers, construction-focused refugees should take priority. If research is slowing you down, shift investment accordingly.

 

When to Spend Your Tickets

Timing your pulls can further improve efficiency. In some cases, recruitment contributes to event scoring—such as alliance-based events—allowing you to gain additional rewards while summoning. If you can align your pulls with these events, you gain extra value without additional cost.

However, this should not override good decision-making. If a top-tier refugee appears, securing it immediately is usually more valuable than waiting for perfect timing.

 

Spending Considerations

Spending on refugees through direct purchase offers is generally inefficient compared to optimizing your recruitment strategy and resource flow. Most paid options provide limited value relative to what you can achieve through consistent ticket farming and smart pulls.

Some limited-time offers may appear attractive because they guarantee higher rarity refugees. However, unless they significantly outperform your current setup or align with your core buildings, they rarely justify the cost.
