Alliance features arrive quietly, tied to a level most members never look at. Here is the whole structure, from First Fun's own English documentation.
Ranks and the four officer jobs
An alliance holds up to 100 members in 5 ranks: R5 the leader, R4 officers, R3 key members, R2 important members, R1 newcomers. Only R5 can promote or demote R4 and assign the officer roles; every R4 and R5 can promote and demote R1 through R3.
The R4 roles are not decoration — the publisher gives each a job:
| Officer | Responsible for |
|---|---|
| Warlord | Attack and defense strategy, territory expansion, leading wars |
| Recruiter | Finding new members, daily member tasks |
| Muse | Morale and the general atmosphere of the alliance |
| Butler | Daily member tasks, planning alliance events |
Alliance Gift Level — the progression that gates the features
| Gift Level | Unlocks |
|---|---|
| Lv.5 | R4 and R5 can send Alliance Mails |
| Lv.6 | Members can send images in alliance chat |
| Lv.10 | R4 member cap rises from 8 to 10 |
| Lv.15 | One-tap claim for Premium Gifts |
Gifts come in two kinds. [Regular] gifts drop from defeating Doom Elites. [Premium] gifts are granted to every member when someone buys a pack that contains Alliance Gifts — and a buyer who would rather not advertise it can [Hide your name on gifts]. Alliance Mail, once unlocked, can be targeted at specific ranks: R4, R3, R2 or R1.
Alliance Help is worth more than it looks, and it is capped
Each help reduces a timer by 0.5% of the remaining time or 1 minute, whichever is greater. On a long build that is a percentage; on a short one it is a flat minute — which is why helping is never wasted on small timers.
The catch: the contribution points you earn from helping are capped per day. If your contribution stops moving while the help button still works, you have hit the cap, not a bug. The remaining daily limit is shown inside [Alliance Help].
Assembly Point, Teleporter and the alliance map
The [Alliance Assembly Point] is the purple banner your R5 or R4 plants on the map, and the [Alliance Teleporter] moves your base as close to it as it can get. During Saturday's Enemy Buster stage, attackers are shown the enemy Assembly Point as a suggested relocation spot — which is exactly as aggressive as it sounds, and worth knowing before you wonder why a hostile alliance materialised next door.
[Alliance City] lists every city you occupy plus all neutral cities, with coordinates, levels and the buffs each one carries: Iron Production, Research Speed, Coin Production, Gathering Speed, Food Production, March Speed, Building Speed, Training Speed and Unit Healing Speed. Read it before a campaign — see capturing cities and the Capitol.
Joining and leaving
The alliance list shows Tag, Name, Total Power, Member Count, Primary Language and Join Requirements — either Open or Approval-Based — and [Alliance Rankings] sorts by power. [Quick Join] drops you into the highest-ranked alliance currently available, which is convenient and almost never the alliance you would have chosen on language and activity. Sharing an [Alliance Invitation] costs 200 Diamonds. To leave: [Alliance] → [Settings] → [Leave Alliance] — but check what leaving does to your Alliance Duel points and rewards first.
