Coordinate Alliance City Buffs for Maximum Efficient Progression
City Buffs in Infinity Kingdom are a powerful but often underutilized tool that can significantly impact the progression speed of an alliance. With the right coordination, alliances can optimize building speed, technology research, and dragon upgrades, allowing their members to advance faster while saving valuable speedups. In this guide, we’ll cover how and why alliances should coordinate these buffs efficiently to maximize progression.

Understanding City Buffs and Their Importance
Across Norheim, there are multiple cities that provide buffs to enhance progression efficiency. While some cities offer combat buffs, we’ll focus on the ones that grant economic progression buffs, which include:
- Building Speed Buff (+3%) – Reduces the time required for construction upgrades.
- Technology Research Speed Buff (+3%) – Speeds up research, allowing faster unlocks and upgrades.
- Dragon Upgrade Speed Buff (+3%) – Reduces the time needed for leveling up dragons.
Buff Distribution in Norheim
- Dragon Upgrade Speed Buff Cities: 19 total, 3 also provide combat buffs.
- Building Speed Buff Cities: 13 total, 4 also provide combat buffs.
- Technology Research Speed Buff Cities: 11 total, 3 also provide combat buffs.
See complete list of all cities and buffs on the bottom of this guide.
Since combat buffs apply to all alliance members, but economic buffs only apply to the mayor, strategic distribution is essential for efficiency.
Strategic Coordination of City Buffs
1. Distributing Cities Among Alliances
To ensure all active alliances benefit from city buffs, the strongest alliances should control cities with combat buffs, while the remaining cities should be distributed among other active alliances. This ensures:
- Top alliances retain an edge in combat while maintaining economic efficiency.
- Mid-tier alliances have access to valuable speed buffs, improving server-wide progression.
- No single alliance hoards all buff cities, promoting server balance.

2. Setting Up Communication for City Buff Requests
To maximize the use of buffs, alliances should establish a dedicated communication channel for city buff management. This ensures that:
- Players can request a buff before major upgrades.
- Officers can quickly assign mayorship to the requesting player.
- Players return the position after activating their upgrade.

A simple chat format could be:
📢 Request: “Please assign me Dragon Buff for my upgrade.”
🔄 Officer Action: Assigns mayor position and tags the player.
✅ Player Response: Starts upgrade and immediately steps down from mayorship.
3. Assigning and Rotating City Mayors
Since only one player at a time benefits from the mayor’s buff, quick transitions are key.

- Officers should check requests regularly and promptly assign mayorship.
- Players must release the role immediately after initiating an upgrade.
- Officers now have the ability to remove inactive mayors, ensuring smooth rotation.
4. Understanding Buff Activation Timing
Unlike combat buffs that apply continuously, economic buffs only need to be active at the start of an upgrade. This means:
- Players do not need to hold mayorship for the entire duration of an upgrade.
- Once the upgrade starts, the buff locks in, and the player can vacate the position.
- Another player can then request the buff, ensuring maximum efficiency.
5. Leadership Responsibility and Long-Term Benefits
While this requires some attention from officers, it is not difficult to manage. The long-term benefits include:
- Consistently saving speedups for every alliance member.
- Faster individual progression, leading to stronger alliances overall.
- Better coordination between alliances, strengthening server-wide cooperation.
New Officer Controls: Removing Mayors
Previously, players had to manually step down from mayorship, leading to bottlenecks when someone forgot. However, a recent game update now allows officers to remove players from the mayor position, ensuring a smooth transition when another player requests the buff.

Final Thoughts
Properly managing City Buffs can provide a huge advantage for alliances willing to coordinate. By setting up efficient communication channels, distributing cities strategically, and rotating mayors quickly, alliances can drastically reduce upgrade times, save speedups, and grow stronger together.
🔥 A well-organized alliance is a powerful alliance! 🔥
