Spread across the King of Avalon kingdom map are Barbarian Camps of various levels. Successfully defeating the barbarian captains of these camps through a rally of minimum 2, maximum 6 alliance members, will award you with resource items, barbarian chests, bonus barbarian chests (if you hold a barbarian chest key), and possibly a special event item such as tainted daggers (when an applicable event is currently running).
Camp and Captain Levels
Each camp is indicated by a level, and will contain barbarian captains of a range of levels near that. For instance, a level 18 barbarian camp will most likely hold barbarian captains of levels 15 through 21, with the majority of the captains being of the same level (or +/-1) as the camp. The higher the level of the captain, the tougher the fight, but also the better the rewards.
From what I could find out by looking at camps on the map, these are the camp levels and their possibly barbarian leader levels:
- Camp 6? (1-6?)
- Camp 9 (6-11)
- Camp 12 (9-15)
- Camp 15 (12-18)
- Camp 18 (15-21)
- Camp 21 (18-24)
- Camp 24 (21-27)
- Camp 27 (24-30)
- Camp 30 (27-30)
Barbarian Chest Levels
Each barbarian captain's level determines the level of the barbarian chest, and bonus barbarian chest he guards. The higher the level of the chest, the better the rewards. The levels of the chests are tiered as follows:
- Barbarian Captains level 1-5?: Barbarian Chest Lv 1
- Barbarian Captains level 6?-10: Barbarian Chest Lv 2
- Barbarian Captains level 11-15: Barbarian Chest Lv 3
- Barbarian Captains level 16-20: Barbarian Chest Lv 4
- Barbarian Captains level 20-25: Barbarian Chest Lv 5
- Barbarian Captains level 26-30: Barbarian Chest Lv 6
Rallying a barbarian Camp Captain
To defeat a barbarian camp captain, you need to rally it. This will cost 20 stamina, and you will need to have at least one more member in your alliance to join you in your rally. While war rallies can be expanded by researching more rally slots through alliance tech donations, barbarian camp rallies are limited to just 6 slots, regardless of alliance research.
If you fail to defeat the captain, your stamina points will be refunded as soon as your troops return home.
While it is tempting to just fill up an existing rally, it might be wiser to start a second one to maximise the rewards, as each barbarian camp rally has a fixed amount of resources to be divided between all rally members. For a level 30 captain, this is 400k food or wood. So, if a rally already has enough power to defeat the barbarian captain, please consider starting another rally against a different captain. If your rally doesn't get enough participants, you can always consider disbanding it and joining the other rally.
Sometimes members will want to try to 'solo' a barb for this reason, and will try to take it on with just their farm account(s). Please follow this request, and don't join it anyway, or at least ask before joining. It's not meant by them as a-social, or greedy, but rather as a way for everyone to maximise their rewards. Try to host your own, and if you don't get enough participants, just ask if you can join theirs anyway.
If you run a solo barb, or a barb with specific restrictions (such as infantry- or siege-only), please post this request in the alliance chat directly before or after the rally is started. If you plan on running multiple solo barbs, it'd be wise to click on your message to copy it, so you can easily repeat it after every (other) rally, so others don't have to scroll up to your first rally.
Regardless, please check the alliance chat before joining any rally. Not just because it might be a solo barb, but also because it could be a 'fake rally' meant to increase stamina beyond 100, or to trick enemies into thinking there are less troops in the stronghold than there really are!
