Honor Points

Honor points are awarded (or subtracted) during combat with other players. The total number of honor points (or negative honor points) a player has determines how much loot another player can obtain from him or her during a raid.

Basics
Honor points are gained or lost in the following scenarios:
 * Players with "yellow" names in galaxy view are honorable targets. It you attack such a player you will gain honor points. If such a player attacks you, then you will gain honor points while he or she may lose them.
 * Players with "white" names in galaxy view are not viewed as honorable targets. If you attack such a player you will lose honor points. If such a player attacks you, he or she will gain honor points while you lose them.
 * Alliance members and inactive players are considered neutral. Any attacks (such as moonshots from an alliance member or raids against inactive) will not change your honor point totals.

The use of ACS can change the type of attack. For example, if a player is an honorable target for you, but a stronger player joins you via ACS, you may lose honor points.

When attacking different players, you can plunder varying amounts of resources:
 * Attacks that are against neutral targets or not honorable give 50% resource plunder
 * Attacks against honorable targets give 75% resource plunder
 * Attacks against bandits (explained below) give 100% resource plunder

Formula
The formula for calculating your HP is:

HP = (Units destroyed ^ 0.9) / 1000 (civil ships and rebuilt defences don't count, normally 70% of defenses are rebuilt)

For a fight to be honorable you need to fulfill one of the following requirements: Excluded from this are Alliance members, buddies and inactives. => they are neutral, so you can neither gain nor lose HP from them.
 * At the moment of the fight the attacker has fewer military points than the target
 * If the attacker has more military points than his target, he must fulfil one of the following: - At the moment of fight the target has more than 50% of the attackers military points - At the moment of fight the target only has up to 10 military points less than the attacker - At the moment of fight the target is no more than 100 military ranks behind the attacker - At the moment of fight the target has a bandit rank.

NOTE: A player can earn or lose honor points if he has at least 1% of all ships in the combat.

example: if you destroyed 10 LF: HP = (40,000 ^ 0.9) / 1000 = 13.86 = 13 HP

The attacker will earn HP for the defender's units he destroys. The defender will earn HP for any of the attacker's units he destroys.

ACS Attack
Honorable only if one of the following is met:
 * The military points of the defender is not less than 50% of the sum of the attackers military points.
 * Defender is a bandit

ACS Defend:
Honorable only if one of the following is met:
 * The military points of the attackers are not less than 50% of the sum of the defenders military points.
 * One of the attackers is a bandit

Honor points ratings
These are marked on players in the leaderboards

The following are the "good" honor point ratings
 * Grand Emperor (Top 10 HP Ranking and at least 15,000 HP)
 * Emperor (Top 100 HP Ranking and at least 2,500 HP)
 * Star Lord (Top 250 HP Ranking and at least 500 HP)

The following are the "bad" honor point ratings
 * Bandit (Bottom 250 HP Ranking and at least -500 HP)
 * Bandit Lord (Bottom 100 HP Ranking and at least -2,500 HP)
 * Bandit King (Bottom 10 HP Ranking and at least -15,000 HP)

Advantages

 * Have a high amount of honor points means those who raid you can only take part of your resources.
 * Other players may see you as "honorable" or not attacking weaker players. They may be more likely to trust you.
 * You can use Honor points to bid in an auction. 1 Honor point can exchange to 100 bid points. However any honor points exchanged in this manner are non-refundable.

Disadvantages

 * All battles against said person are honorable battles, and thus they'll never flee.
 * Being a Bandit (or higher) means that if someone attacks you and wins, they steal all your resources (yes, that's 100% resource capture).
