Raiding other Captains' Havens is definitely the most satisfying way to earn Resources in the game.
To conduct a Raid, choose the number and type of Units you want to send. If your Raid is successful, you will seize a certain number of Resources. The amount of Resources seized depends on the carrying capacity the Units that survived the Raid. After the Raid you will receive a report from your Master at Arms detailing the number of casualties and the amount of Resources your Units claimed.
You can gain a max of 10 raids. When you use raids, you will gain 1 back every 2.5 hours, up to the max of 10. Any Raids in excess of the allotted 10 will not result in any acquired resources. You can view the current number of Raids available at the Pirate Stronghold ("Captain's Log" tab) or on the Map by positioning your mouse on other Captain's Haven.
After you've reached the daily Raid limit, you can still send your Crew to raid other Havens, but they won't seize any more Resources. You can capture no more than 50% of the enemy's Warehouse capacity in each raid, and 5% of captured Resources will be subtracted as the cost of the Raid. If the Haven has already been raided to its limit by other players, or the amount of Resources in Warehouse is less than 50% of its capacity, the Raider will get 5% of Resources stored in Warehouse at the time of the Raid.
Also, you can only take a maximum of 50,000 in resources per week from 1 haven. A week is defined by a running 7 days, meaning if you hit the maximum resource cap on a Monday you will not be able to collect again until the following Monday. This is to allow time for you opponent to regenerate their resources.
A Raid can be performed in 2 ways:
From the Map:
- Click «Map» in your Haven.
- Place the mouse over the Haven you want to raid.
- Choose «Raid» on the Haven menu.
From inside the enemy's Haven:
- Go visit the Haven of the player you want to raid.
