Aggression increases the attack of the fleet and defense in battle by % equal to its level. Aggression is awarded for each % of the fleet or defense destroyed in battle from total player statistics points. For example, an enemy has 1 000 000 points and you killed his fleet and defense in battle by 90 000 points. The enemy's aggression against you will increase by 9 levels.
In calculating the aggression it is considered that all pirates have 10 000 points.
Every day the aggression is reduced by the root of the current level.
