Wonder

Wonders of the world provide bonuses to all dominions in the controlling realm and are acquired by destroying and rebuilding them. They are categorized into two tiers based on their bonuses with tier 1 generally referring to stronger wonders.

Wonder Discovery and HP

The starting wave appears at round creation with two Tier 1 wonders and one Tier 2 wonder. Tier 1 wonders start with 150,000 power and Tier 2 wonders start with 75,000 power.

After the starting wave, the daily tick attempts to spawn a new wonder every 3 days while fewer than 6 wonders exist. Before day 9 only Tier 2 wonders are eligible, day 9 is limited to City of Gold, Fountain of Youth, or Horn of Plenty, and later spawns are Tier 1.

Once rebuilt, wonder power depends on the damage dealt to it by your realm and time into the round given as:

$min(37500*DayInRound,2*OriginalWonderPower)*\frac{DamageDealtByRealm}{OriginalWonderPower}$

The rebuilt wonder has a minimum of 150,000 HP and is rounded to the nearest 10,000 HP.

A round can have at most 6 wonders.

Attacking and Destroying Wonders

Troop attacks on wonders use raw offense, with applicable wonder-damage technology and hero bonuses. Your army suffers 3.5% casualties regardless of any casualty modifiers (including immortal units). The only exception is Gnome Suicide Squads, which always suffer 50% casualties.

The spell Cyclone can also be used to damage a wonder. Cyclone damage is capped at 1 WPA and can only deal a maximum of 0.75% of a wonders base HP. Unlike other targeted spells, Cyclone cannot be repelled. Cyclone deals damage as given by

$min(1.5*WPA*Acres,WonderBaseHP*0.75\mathrm{\%})$

where WPA is capped at 1.0 for purposes of damage calculations.

When attacking a neutral wonder, the damage is doubled but still capped at 0.75% of the wonder's base HP.

If a dominion on 2,000 acres with 0.5 WPA casts cyclone on a 250,000 HP wonder, that dominion will deal damage of

$min(1.5*0.5*2000,250000*0.75\mathrm{\%})=min(1500,1875)=1500$

while a dominion running 0.75 WPA on the same land and casting on the same wonder will deal

$min(1.5*0.75*2000,250000*0.75\mathrm{\%})=min(2250,1875)=1875$

Damage from a troop attack or Cyclone cannot exceed the wonder's remaining power. Overkill does not count toward recorded damage or damage contributions used for rewards.

Wonder Prestige

Each dominion that participates in destroying a wonder that is controlled by another realm is awarded prestige.

Prestige is only awarded via troop damage to individual dominions as per

$25+\frac{TroopDamage}{DamageDealtByRealm}*250$

To be eligible for prestige, a dominion must deal at least 1.9% of the realm's total damage to the wonder. Prestige gain is capped at 75, which means that max prestige gain occurs at 20% damage contribution. Sending more will not increase prestige gains.

Cyclone damage does not award prestige.
