Celebrations & the Festival Grounds
Festival Grounds celebrations spend resources for immediate Culture Points. Festival Grounds requires Town Hall 10 and Academy 10.
Tea Party and Grand Ball
| Celebration | Cost | CP basis | Base duration |
|---|---|---|---|
| Tea Party | 6,400 / 6,650 / 5,940 / 1,340 | Village base daily CP, capped | 24 hours |
| Grand Ball | 29,700 / 33,250 / 32,000 / 6,700 | Account eligible daily CP, capped | 60 hours |
Grand Ball requires Festival Grounds level 10. The caps are 500 / 2,000 at 1× and 2×, 250 / 1,000 at 3× and 5×, and 125 / 500 at 10×.
Server speed changes the base duration by bracket: full duration on 1×/2×, half on 3×/5×, and quarter on 10×. Festival Grounds then reduces it linearly from its level-1 multiplier of 38/38 to 19/38 at level 20. The building level does not increase the CP award.
Celebrations queue sequentially. Queue capacity follows the Town Hall upgrade-queue capacity, and CP for a queued celebration is awarded when that celebration starts.
City interaction
A City’s +200 base CP participates in celebration calculations. Its 1.25 passive multiplier also affects the stored daily CP production used by the profile total.
Stormbrew Celebration
Stormfang’s capital-only Stormbrew Works hosts a separate celebration costing 3,870 / 1,680 / 215 / 10,900. Its base duration is 72 hours with the same speed bracket scaling. While active, attacks from every Stormfang village gain 1% attack per Works level, but catapult targets become random and leader persuasion is halved. Stormbrew awards no CP.
