Furylord Tips

Furylord spawns 4 times daily (00:00, 06:00, 12:00, 18:00) except Sundays:

• Use all 4 attacks daily — Even without fuel, spend fuel cans (you get 5 back from rewards)
• 3M damage goal — Unlocks full purple A-tier gear from achievements
• Faction bonus: Wait for your faction's 50% damage day to maximize achievements
• Only highest single hit counts — Focus on one big hit, not multiple small ones

Growth-First Approach

One F2P player reached level 28 spending only $3 with this strategy:

• First 4 months: ONLY invest in growth research
• Skip military research early — Focus on construction/research speed
• After growth maxed: Rapid troop advancement in just 2 months

Result: Slower early game, but catches up and surpasses players who spread resources thin.

Speed Boost Targets

Aim for 200% total boost through:

• Villa upgrades — Construction speed
• Bookstore upgrades — Research speed
• Sophia (3-star) — Construction bonus (see Heroes)
• Amelia — Research bonus
• Refugees — Butlers (construction), Scientists (research)
• Shelter research — Growth tree completion

Check Calendar Before Buying

Items become significantly more valuable when paired with active events:

• Golden Wrenches — Best during Vehicle Boost events
• Speedups — Use during Alliance Duel days
• Wrenches/Speedups — Score points in Full Preparedness
• Power Cores — Merit Shop during SVS only

Alliance Duel Sync

Save resources for the right days (see Alliance Duel Guide):

• Monday: Golden Wrenches, blueprints
• Tuesday: Construction speedups
• Wednesday: Research speedups, badges
• Thursday: Hero fragments, power cores
• Friday: Training speedups
• Saturday: Combat — troop usage, attack events
