The Teutons' capital-only celebration building. While its celebration runs, every attacking army on the account hits harder - whatever tribe it belongs to - and pays for it with blunt catapults.

• Each level adds 1% attack, reaching +20% at level 20, and it is applied at the moment the battle resolves rather than when the troops were sent.
• It is account-wide and tribe-blind: a Roman or Spartan hammer hits harder because a Teuton capital somewhere is holding a celebration.
• The price is precision. While the celebration runs, catapults pick targets at random and ignore the building-or-field choice entirely, and administrators persuade only half as well.
• That suits the first heavy wave, the one meant to break the wall and kill the defence, where what the catapults happen to hit matters less than how hard the army lands.
• Destroyed mid-celebration, the attack bonus and the random targeting stop at once but the administrator penalty stays. Rebuilding it - even in another village - restores all three together.

Strategy. It is the one bonus an alliance can hand to armies that are not its own tribe, so a single very active Teuton is worth more to a confederacy than the capital slot costs him. The extra attack also moves the breakpoints for clearing farms, which can let a smaller party take a target it otherwise could not - but only while a celebration is actually running, so it is not something to plan a farming route around.
