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 first wave of wonders will appear at the start of the round with a starting power of 250,000 for tier 1 and 150,000 for tier 2.

An additional wonder will appear every 48 hours beginning on day 6 with a starting power dependent on the wonder tier.

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

$min(42500*DayInRound,2*OriginalWonderPower)*{\frac {DamageDealtByRealm}{OriginalWonderPower}}$

The total number of wonders that will be discovered and appear in any given round is a max of 40% of the number of active realms. If there are 29 realms, 12 wonders would spawn as per

$40\%*29=11.6\approx 12$

Attacking and Destroying Wonders

When attacking wonders, your offense is unmodded (except by morale) and always 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

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

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

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

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

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

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