City Capture & Defense Guide

Resources below Warehouse capacity cannot be raided

Your Warehouse protects a fixed amount of each resource type. Any resources inside that threshold are completely safe — no shield needed. Check your Warehouse capacity and only shield when your stockpile exceeds it.

Spend resources before logging off

Queue a long building upgrade or troop training batch before going offline. Committed resources (actively being consumed by an upgrade) cannot be raided. This is more efficient than shielding defensively.

Shield windows: Friday night and event peaks

Enemy Buster, State Ruler, and cross-server events dramatically increase attack frequency. Shield before high-risk windows, especially Friday nights heading into weekend raid periods. Maintain 2,000 diamonds as a fallback if Alliance Shop shields sell out.

Set your strongest heroes on the wall before going offline

Wall defense draws from your active hero formation. Before logging off, switch to your highest-ATK/highest-HP combat formation — not your resource or research heroes. This applies during Zombie Siege too.

Recall all troops before risky periods

Troops out on marches or gathering cannot defend your base. If a raid or rally lands while your best troops are mining, your wall defense is significantly weakened. Recall before going offline near high-risk windows.

Alliance reinforcement is multiplicative

Alliance members reinforcing your base stack with your own garrison. Communicate in alliance chat when under attack — a reinforced base with 5 members' troops can repel attacks that would otherwise kill your garrison. Ask for help immediately.

Scout before every march

Scouting reveals the target's troop count, composition, and hero formation before you commit. A base with high power but low kill count is likely a trap account or an inactive account with no real combat setup — scout before wasting troops.

Target bases above their Warehouse threshold

Only attack bases that are visibly over-stored on resources (farms/food/wood piles visible in city view). Attacking a well-managed base with resources inside Warehouse protection yields nothing and wastes your hospital capacity.

Use rallies for strong targets

Solo marches against high-power bases typically lose troops permanently. Alliance rallies multiply your effective march size — 6–8 members rallying together can crack targets a solo player cannot. Rally leadership should match troop timing to minimise the first-attacker penalty.

Time attacks during Enemy Buster

Enemy Buster is active periodically (check Events). During Enemy Buster on Saturdays specifically, hospital capacity doubles — meaning fewer permanent troop losses from attacks. Co-ordinating offensive pushes during this window reduces your losses significantly.

Trap accounts: HQ27 + T9 troops

A trap account appears weak (HQ27, low power stat) but fields near-endgame combat troops (T9). Attackers who scout and see “low power” march in — and lose troops permanently to a far stronger defense than expected. Do not attack HQ27+ bases that have suspiciously high kill counts.
