When I started playing Last Z, I made the classic mistake: I invested fragments equally into every hero I owned. After a month, I realized my B-rank heroes were completely useless in my main formation โ I had wasted resources that could have gone into my S heroes. I completely changed my strategy.
The #1 rule I learned: focus on your 3 strongest S heroes from your main faction and leave the 2 weakest at base level. You'll replace them next season anyway. The faction order is: S1 Blood Rose โ S2 Wings of Dawn โ S3 Order Guard.
๐ฐ The 3 Factions & Their Season Order
๐น Blood Rose โ Season 1
The first faction. Lysia + Bella together activate one of the strongest combos โ increased damage resistance against Assault units. Sofia is essential for new players: her skill 3 passively reduces construction time even when not in combat. If you're just starting, focus here.
๐๏ธ Wings of Dawn โ Season 2
Long-range shooters. Alma and Scarlett are pillars โ both have exclusive gear that keeps them competitive in Season 3. Laura is the only reliable free frontline. Emilia's global research passive saves Laboratory resources.
๐ก๏ธ Order Guard โ Season 3
The Biker faction. Chinatsu is valuable in Alliance Versus events for duel points. Halina is the best S2 frontline โ very tanky with good Biker damage.
๐ Tier System: What Each Rank Means
S TierMost powerful heroes. Very high base stats and passives that affect the whole formation. Invest heavy fragments here โ especially skill 3. Most obtained via season pass or special events.
A TierTransition heroes โ useful early but replaced once you complete your S team. Universal A fragments are perfect for secondary formations.
B TierUseful early for resource gathering. Once all skills maxed, Blue Manuals can be recycled for resources and even S fragments.
โ ๏ธ Important โ Skill 3 "Active in Expeditions": Some heroes have skill 3 labeled "Active in Expeditions" โ the buff only applies when deployed. Others say "Effective on all troops" โ applies even if not in team. Affected: Lysia, Bella, Selena, Nyx, Alma, Sakura, Halina, Chinatsu.
๐ก What I Learned About Hero Investment
๐ฏRule of the 3 S heroes: Focus all fragments on your 3 strongest S heroes. The 2 weakest will be replaced next season.
๐Prioritize Skill 3: For supports like Sofia, Oliveira, Emilia, Laura, Mia โ skill 3 is a global passive that works even when not in combat.
โธ๏ธDon't waste EXP on A or B heroes: Save all experience to instantly level up S heroes when you unlock next HQ level.
๐ฎPlan with season vision: When a new S hero arrives, evaluate if they fit your main faction. If not, wait for your faction's season.
๐ How to Get S Hero Fragments as F2P
Increase VIP level for extra missions. Daily truck robberies/sends give fragments. Season events reward S fragments. Most importantly: alliance ranking at end of season โ leader distributes diamonds and exclusive tickets to recruit S heroes you didn't buy. Being in a strong, active alliance is key.
โป๏ธ Advanced Tip: Recycle Your Blue Skill Manuals from B Heroes
Once all B heroes have max skills, Blue Manuals pile up. Go to Warehouse โ Hero tab โ find Blue Skill Manuals โ select "Recycle". Each manual turns into a Random Basic Resource Box that can give wood, electricity, food, Z Coins, diamonds, or even S-rank hero fragments. Don't waste them.
