Turmoil Surge

Marauders attack every prison in your alliance in 20 waves. Defend your own prison, reinforce allies, and protect the alliance’s Sentry Turrets on the Siege waves.

You need 2 Sentry Turrets built. Clear a level without losing a turret to unlock the next. None of your troops die here.

0%

Setting up

  • •An R4+ picks the difficulty and starts it now or books a start time.
  • •The alliance needs 2 Sentry Turrets in its territory (up to 4 can be built).
  • •Unlocking the next level: clear the one before without losing a turret, and reach its alliance points: Lv.2 needs 26M, then +2M per level up to Lv.13 (48M), then +4M per level up to Lv.20 (76M).

The waves

WavesWho they attackPoints
Most wavesEvery member’s prisonLv.1: 6,000 rising to 49,200 · Lv.20: 11,700 rising to 95,940
7, 14, 17 (Frenzy)Online members onlyAbout twice a normal wave (Lv.1: 40,800, 74,400, 88,800)
10, 20 (Siege Marauders)Every Sentry TurretNo personal points; they set the turret bonus

All waves together are worth 598,800 points per prison at Lv.1, 868,260 at Lv.10 and 1,167,660 at Lv.20. A prison defense is a win if at least 50% of the attackers die. You score your own kills even when reinforcing an ally (it doesn’t take points from them). Garrisoning a turret gives no personal points.

Turret bonus

For 90 seconds after each Siege wave, alliance points get a bonus that depends on the Siege Marauder level and how many of the 4 turret fights you won: at Lv.1, +0%, +10%, +20%, +30% or +40%, going up by 20% each level to +580% to +620% at Lv.30. Win all 4 turret fights and the next Siege Marauder level goes up by one; lose all 4 and it goes down by one.

Rewards

Your personal points and your alliance’s points must both reach a tier: 6,000 and 600,000 gives 4,000 Contribution, up to 200,000 and 54M for 24,000. From 300,000 and 60M, tiers give Precious, Rare and Common Trove Souvenir Coins, up to 4M and 110M.

Rankings settle at 12:00 server time the next day, and you must still be in the alliance. Personal top 1,000, #1: 20 Precious, 300 Rare and 28,200 Common Trove coins plus resources. Alliance top 10, #1: 10 Precious, 100 Rare and 5,000 Common.
