Alliance level and common bonuses

How it works

• Level formula: min(20, 1 + ⌊total donations ÷ 50,000⌋); all members' treasury donations are summed regardless of resource type.
• Production bonus: (level − 1) × 0.5%, at most +9.5%; applied as a multiplier to passive wood, stone, food, iron and gold production in all your villages.
• Combat bonus: (level − 1) × 0.25%, at most +4.75%; applied to attack power in player attacks and to defence power against player and NPC raids.
• Players who are not members of any alliance cannot receive this battle support; instead they get a fixed +6% strength bonus in defense ONLY. Attack strength is untouched; on joining an alliance this bonus is removed and the alliance battle support takes over.
• The bonus is calculated from the alliance level at the moment of arrival and only for membership in the active world; it disappears when you leave the alliance.
• A donation that raises the level instantly settles every member's accrued production at the old rate; the new rate applies to production from that moment on.
• Example: in a level 12 alliance, production is +5.5% and combat +2.75%; level 12 requires 550,000 total donations.

Step by step

1. Open the current level, progress, and next threshold information on the Alliance home screen.
2. Compare treasury donations, member contributions, and the impact of season activities on progress.
3. Examine open production, war, or management bonuses from the bonuses section.
4. Verify that the effect is applied from its resource generation and related power summaries when the new level is opened.
