Last Z Hero Upgrade Guide: Which Heroes to Upgrade First

Hey, guys~~! Here's the thing about Last Z: upgrading the wrong heroes early doesn't just slow you down—it locks your account into weeks of wasted resources, slower upgrades, weaker troops, and missed opportunities. Meanwhile, the players who know which heroes actually matter? They're growing faster, recovering from battles quicker, and dominating their servers while the rest of the server is scratching their heads wondering why their "strong-looking" squad keeps getting crushed .

This guide isn't another generic "who hits hardest" list. I'm going to break down exactly which heroes deserve your precious stars and skill books, which ones are just noob traps, and how your upgrade priorities shift from Day 1 all the way through Season 4. Let's fix your hero roster for good.

Understanding Hero Value in Last Z

Before we dive into the rankings, you need to understand something that separates top players from the rest: the third skill is where the real value lives.

Most new players look at combat stats and active abilities. They see big damage numbers and think "this hero is OP." But experienced players know that the third skill—the one that gives permanent account bonuses like construction speed, research speed, troop training speed, fuel efficiency, and alliance duel points—is what actually accelerates your entire account .

These aren't temporary combat buffs. They're permanent multipliers that make everything you do faster and cheaper. And the only way to max them out? Starring up your heroes and upgrading that third skill.

Another thing: stars matter more than levels early game. A 5-star blue hero with a maxed third skill often delivers more long-term value than a 1-star orange hero sitting pretty in your roster but doing nothing for your progression .

Early Game Heroes: Build Your Foundation

When you first start Last Z, you'll mostly have access to blue and purple heroes. Don't sleep on them—several are absolute beasts for early progression .

Blue Heroes Worth Your Resources

Angelina, William, and Audrey should be on your radar immediately. Their third skills boost troop training speed by 30%.

Why does this matter? Because in the early game, your primary resource strategy should be looting other headquarters, not gathering. Looting gives more resources faster, but you will lose troops. Faster training speed means faster recovery, which means more looting cycles, which means more resources. It's a compounding advantage .

These aren't heroes you build for combat. You build them because they let you lose troops without losing momentum.

Purple Heroes That Punch Above Their Weight

Maria is the standout purple hero. Her third skill boosts training speed by 50% and reduces troop-related research costs. That combination directly improves your rebuild efficiency—exactly what early accounts need .

Vivian earns her spot for a different reason. She improves damage against map creeps and, more importantly, reduces fuel costs for boomer fights. Less fuel per kill means more farming volume over time. At higher star levels, her benefit applies without needing deployment, making her a permanent farming asset .

The Noob Traps to Avoid

Stay away from Athena, Natalie, and Jazelle early on. They're gathering heroes, and gathering is NOT your priority in the early game. Combat-based resource acquisition through looting is far more efficient until you're well into the mid-game .

 

The Big Six: Foundation Orange Heroes

Once you start unlocking orange heroes, your focus should shift to what I call the "Big Six." These heroes form the engine of your entire account. If you build them early and correctly, you'll operate on a completely different timeline than players chasing short-term combat power .

Sophia – Construction Acceleration

Sophia is arguably the highest-priority hero you can build early, and she never truly falls off .

Third skill provides:

• Up to 90 minutes of free construction time
• Up to 40% construction speed

Construction never stops in Last Z. Every building upgrade, every prerequisite, every bottleneck benefits from this bonus. The earlier you star Sophia up, the more total time you save across your entire account life. This isn't a hero you unlock and forget—she's a hero you build deliberately .

Amelia – Research Speed

If Sophia accelerates your city, Amelia accelerates your lab .

Third skill provides:

• Up to 90 minutes of free research time
• Up to 40% research speed
• Up to 15% reduction in basic research resource costs

Research is a constant pressure point at every stage. Faster research means faster power unlocks and smoother progression. Like Sophia, Amelia's value isn't flashy—it's structural .

Mia – Vehicle Progression

Mia is one of the strongest early accelerators, especially if you care about clean power growth .

Third skill provides:

• Up to 500 free vehicle blueprints per day
• Up to 30% extra experience from modification upgrades

Vehicles are one of the fastest ways to gain power early. More blueprints mean more upgrades, and more upgrades mean faster access to higher vehicle tiers. At higher star levels, Mia also boosts vehicle skill damage, making her relevant beyond pure progression .

Katrina – Fuel Economy

Katrina's value evolves as your account grows. Early on, she helps with leveling. Later, her third skill becomes one of the most important resource-generation passives in the game .

Third skill provides:

• +100 fuel per day
• +10% fuel restoration speed

Fuel is a bottleneck across nearly every activity. Extra fuel every day doesn't feel dramatic, but over weeks and months, it creates a real activity advantage. Katrina remains relevant across all stages because fuel remains relevant across all stages .

Lara – Radar & Alliance Duel Scaling

Lara is a long-term progression hero disguised as an early XP boost .

Third skill provides:

• Up to 20 free radar events per day
• Up to 50% extra experience from radar events

That alone accelerates early growth. But Lara's value increases later when radar events tie directly into Alliance Duel scoring. At higher star levels, she also provides extra exploration chests (up to 10 per day) .

Chinatsu – Alliance Duel Advantage

Chinatsu often looks underwhelming early, which is exactly why she's misplayed .

Third skill provides up to 55% extra Alliance Duel points.Once duels become a regular part of progression, this bonus becomes significant for both personal rewards and alliance outcomes. Pair her with Lara's extra radar events, and you've got a scoring advantage that's hard to match .

 

Season 1: The Faction Shift

Once Season 1 begins (around Weeks 6-8), everything changes. From this point forward, every new hero is orange, and combat power starts scaling around faction deployment, not mixed formations.

Season 1 Batch 1 Heroes

The first wave introduces Aloe Vera (Blood Rose), Evelyn (Guard of Order), and Scarlet (Wings of Dawn). Their third skills provide massive 70% training speed bonuses for specific troop types within their faction—assaulters for Blood Rose, riders for Guard of Order, shooters for Wings of Dawn .

At higher star levels, these bonuses expand and reduce resource costs for training. By five stars, they boost attack and defense for all troop types .

Faction Deployment Bonuses

Season 1 also activates faction deployment bonuses. Each deployed faction hero increases troop attack and defense by 5%. Deploying five heroes from the same faction increases troop capacity by 10% .

This is the moment mixed formations die. Running mixed squads from here on quietly caps your ceiling. Players who adapt to faction play pull ahead; those who don't fall behind .

Season 1 Batch 2 Heroes

The second wave (Selena, Nyx, Sakura) provides large attack and defense boosts for their faction troop types (up to 45% defense) and a passive 10% faction troop damage bonus that works even when the hero isn't deployed. However, the big attack/defense numbers only apply when the hero is actively deployed .

Seasons 2-4: System Commitments

From Season 2 onward, hero upgrades stop being about acceleration and start being about survival and dominance at the top end of play.

Season 2 Heroes

Bella (Blood Rose), Alma (Wings of Dawn), and Harina (Guard of Order) introduce third skills that scale troop health (+15%) and damage (+25%) for faction-specific unit types. Their fourth skills add another 10% troop HP when you deploy five heroes from the same faction .

At this stage, mixed formations don't just underperform—they bleed efficiency. Accounts that hesitate here take higher losses for the same activity .

Season 3 Heroes

Leysa (Blood Rose), Liliana (Wings of Dawn), and Dodaki (Guard of Order)add+90 flat troop capacityand up to 20% hero attack/defense. Their fourth skills introducedamage resistance(7.5%) when paired with specific Season 2 heroes .

Damage resistance is one of the rarest and most impactful stats in Last Z. Accounts without it take disproportionately higher losses in sustained PvP. At five stars, these heroes add another 7.5% troop capacity and extend damage resistance to all unit types .

Season 4 Heroes

Yu Chan (Blood Rose), Queenie (Wings of Dawn), and Amber (Guard of Order)are built aroundskill damage and countering faction disadvantages.

Their third skills increase hero skill damage by 24% (plus another 10% at five stars). Their fourth skills reshape faction matchups: troops deal an additional 10% damage to factions they naturally counter and take 10% less damage from factions that counter them .

These heroes don't delete the counter system—they soften bad matchups and amplify favorable ones. At high PvP levels, that shift is often the difference between controlled wins and unnecessary losses .

 

Final Thoughts

Here's the hard truth about Last Z that nobody tells you straight: hero mistakes are permanent. Every star you waste on the wrong hero isn't just a small setback—it's resources buried in a dead end that only gets harder to fix as seasons roll on.

The players who dominate aren't the ones chasing every new release. They're the ones who figured it out early—that construction speed, training efficiency, and fuel economy are what actually make accounts explode. While everyone else chases damage numbers, they're building foundations that compound.

And by the time factions matter? They're untouchable.
