Battle rules

Winning conditions
The attacker wins when the enemy castle's HP is 0.

The enemy castle can be damaged by two ways:
 * direct damage: the castle can be damaged like any other buildings by troops.
 * breaking the ground: for each tile dropped, an amount of damage is inflicted to the castle.

Main concept

 * When the attack succeeds, the whole island drops and 100% of the loot-able resources are looted.
 * When the attack fails, only the part of the island that dropped will be counted into the looted resources.
 * Loots available by the storages are reduced to 1/3 if destroyed with direct damage.

Routes

 * Routes can be retraced until at least one unit is sent.
 * Routes must start from the outer tiles (displayed in green.)

Units / Spells

 * The units sent will be reusable once they're done attacking in their route. (Spells are not.)
 * When all the units sent are done attacking, a fall down occurs.

Fall down rules

 * When the ground is cut off, the part not connected to the castle will fall down.
 * At each fall down, an amount of damage relative to the amount of the tiles that falls down is inflicted to the castle.

Time limit
There is a time limit of: The game will end when the time exceeds the limit.
 * multiplayer: 3 minutes.
 * single play: 8 minutes.

Number of routes
The attacker can trace 5 routes.

The game will end if the last route is finished.
