Strongholds vs Cities — the protection-lock trick, durability, and what you can build
[RGBB] Raging Black Bulls
Key Insight — The Stronghold Lock Trick
Strongholds get a flat 36-hour protection lock when captured. If a friendly alliance rushes to capture a neutral stronghold, the enemy alliance is locked out for 36 hours from that tile — a real denial / area-control tactic. Cities don't work this way: an attack on a city only drains its durability over time, and that durability recovers only passively over time. There is no equivalent "ally rush" lock for cities — they're a war of attrition.
Stronghold — single-attack model
Capture by attacking the Corruptor boss + zombies guarding the tile. Requires Virus Resistance. One alliance attack/rally either captures it or fails — binary outcome. After capture: 36-hour protection, 1 hour to abandon. 2 strongholds/day max (global across all warzones). Cross-warzone unlocks at Week 3 Day 2 via an Alliance Outpost.
City — durability-drain model
Capture by declaring war (1-hour war duration). Attackers drain the city's durability; defender troops resist. Only R4/R5 can declare. 1 war at a time per alliance. After capture: protection until next Declaration Day 12:00 server time (max ~6-7 days). 2 cities/day max. After Week 4 Day 3, declarations are restricted to Wednesday + Saturday only.

The Stronghold Protection Lock — Strategic Exploit
Because every captured stronghold enters a non-attackable 36-hour state, a friendly alliance can deliberately rush to capture a neutral or enemy-adjacent stronghold before the enemy gets there. The lock window denies them that tile and forces them around your perimeter for 36 hours.
1
Identify the threat tile. Find a neutral stronghold (or an enemy adjacent tile) that gives the rival alliance access to a contested city chain or your home territory.
2
Confirm capability. Verify your alliance has Virus Resistance ≥ the stronghold's requirement (use the VR calculator if rallying). Confirm you haven't already used both daily stronghold slots.
3
Rush the rally. Launch a fully-loaded rally on the Corruptor. A win locks the tile to your alliance for 36 hours — the enemy alliance cannot attack it during that window.
4
Chain-lock the perimeter. If you have multiple strongholds available to capture, lay them in a wall along the contested edge. After ~36hrs, abandon (1 hr) and recapture to refresh — or rotate to an adjacent stronghold and lock that one instead.
5
Budget the cost. Each rush burns 1 of your 2 daily stronghold capture slots and consumes troop healing. Save these slots for high-impact blocks — the strongholds adjacent to enemy outposts or in front of valuable cities.
Important caveat
The 36-hour timer is a published mechanic, not a hidden exploit — every Season 1 source documents the protection window. The "trick" is using it offensively for area denial instead of just defensively after your own captures. There is no rule against it, and it works on captured strongholds in both your home warzone and other warzones.
Why This Trick Doesn't Work on Cities
Cities can't be captured in one attack — they require a 1-hour war declaration during which troops drain the city's durability.
An alliance can only have one active city war at a time, so you can't blitz-capture multiple cities in a single push.
City durability does not regenerate from defenders — only passive recovery over time restores it. A coordinated enemy effort can drain durability across multiple Declaration Days until the city falls.
The 6-7 day protection only kicks in after a successful capture. During war declarations themselves, the city remains attackable.
After Week 4 Day 3, war declarations on cities in other warzones are limited to Wednesday + Saturday, making rush-lock attempts a 2-day-a-week affair anyway.
R4/R5 rank is required to declare war on cities, so the rush has to be initiated by alliance leadership specifically.

Stronghold cap is PER WARZONE — easy to miss
Each warzone tracks its own stronghold cap independently. Placing an Alliance Outpost in a new foreign warzone immediately gives you +3 baseline stronghold capacity in that warzone before any city captures. Then your stronghold cap in that warzone grows by +1 for each Lv 1-5 city and +2 for each Lv 6 city you own in that same warzone.
Worked example: Alliance operating in 5 warzones (1 home, 4 foreign via outposts), holding 7 cities (mix of levels) — observed actual: 25 strongholds.

What You Can Build On / Near Captured Land
Strongholds are mostly territorial markers (no buildable surface), but cities are the construction substrate. There are two distinct build paths: Alliance Outposts (universal cross-warzone tool) and Builder Alliance facilities (mid-season switch).

Builder Alliance — How facility construction works
Builder Alliance unlocks Week 4 of Season 1 (lasts W4-W7). The toggle is irreversible for the rest of the season — switching commits your alliance to construction-focused rewards instead of Influence Points ranking.
Up to 10 distinct facility types, max 3 facilities per city area.
Builder Alliances must abandon captured cities on conversion. Stronghold rules are not explicitly restricted in published documentation — verify in-game before relying on this.
Building Materials come from Daily missions + Radar missions, donated by alliance members. Spy plane delivers in batches of 10 units.
Facilities are built on land owned by any alliance (Builder mode does not require you to own the city — you can support an ally's captured city).
Alliance Outposts — The Cross-Warzone Bridgehead
Placed by R4 or R5 on another warzone's territory. No adjacency required for placement — the outpost itself doesn't need to be next to anything you control.
One outpost per warzone, max 4 outposts per alliance.
Irretractable once placed. If you misplace it, you cannot move it — only destroy and rebuild.
While building, the outpost has a protection status (cannot be attacked until construction completes).
After construction completes: vulnerable to single attacks only — no rallies allowed against outposts.
A destroyed outpost can be rebuilt.
Outpost is required for the first capture in a warzone. Subsequent strongholds in that warzone are captured by chaining adjacency from the outpost-territory.
Members can teleport their base to the outpost's territory to attack from there.
Things To Verify In-Game
Published docs are silent on these — confirm before relying
Whether Builder Alliances may keep their captured strongholds (city abandonment is explicit; stronghold rules are not stated in either FUNFLY Support article or the published guides).
The exact passive city-durability recovery rate (only confirmed that it recovers over time; no published rate found in third-party guides).
Whether the Corruptor defender respawns at a fresh-attack baseline after an Alliance abandons a stronghold and another alliance attempts to capture (likely yes, but undocumented).
Whether defender troops inside a city reduce attacker durability drain rate, or only count as battle losses on defense.
