1. General characteristics and functions
The Tambo building stands for joint attacks and joint defense with your allies.
You will find 2 tabs in the Tambo structure: "Allied Troops" and "My Troops":
(1) Allied Troops: here you will find all external troops stationed in your city:
As featured in our example, there are 2 allied troops stationed at this tambo:
- One troop that belongs to the player "Itzamal" from the city Chichén-Itzá, 236 units;
- the second troop sent by the player "Coyote Ahsa", which came from the city Captogan, 171 units.
(2) My troops: these are your own troops stationed in your friends' cities:
In this example, the player "Ek Holmul" has 4 troops stationed outside his city:
- the first troop as listed above supports the player "Sak Nikté" in Coco Place, 1 unit;
- the second troop supports the player "Kinich Balam" in Nakbe, 12 units.
The second troop is right now being on its way to Chichén-Itzá (a city that belongs to the player Itzamal), by the order of the player Kinich Balam who has been hosting this troop. The troop will arrive in Chichén-Itzá in 1 min. 39 sec.
To use the tambo, the following requirements must be met:
- both players must be in the same tribe
- both players must have a tambo structure in their cities
- the recipient must have sufficient place in their tambo building.
- If you wish to support another player through the tambo, open the travel orders window and select the units to send. After that, select the location where to send support to, then select the "support" option, and press the "send troops" button. Troops sent as support will arrive at the tambo of the recipient.
- Troops sent as support can only be used for attacks and/or defense; they cannot be used for spying other players. Also, it is not possible to transfer support to other players.
- Sending troops through the tambo will produce no changes in the score of the sender/of the recipient; it won't therefore be noticeable for other players when one player sends support to another player.
- The "ownership" of the troops sent through the tambo always remains with the sender: no troops transfer/donation will take place; the support is "leased" by the sender for a purpose (defense/joint attack).
- You can recall your troops through the tambo any time, even if they are being sent to attack a target (in which case the joint attack will be canceled).
- The loot will be distributed according to the strength of each troop that took part in an attack.
2. Defense: how to send and recall support
To send support to another player's city, go to the world map, select the city of the player you wish to support, and select the "Defend ally" option either through the world map or the travel orders window:
And then proceed to fill in your units as you normally would for any other order, and then press the "Send troops" button:
Once the troop makes it to the city, it will automatically find shelter in your friend's Tambo and stay in position for battle until it's recalled or sent back.
How to recall or send back support:
- To send back other players' troops , go to the tambo, click on the tab "allied troops" and press the "send back" button: by doing so, the troops send as support return to the city of the player who sent them.
- To recall your own troops, go to the tambo, click the tab "my troops" and press the recall button: by doing so, your troops stationed at other players' tambos will come home.
3. Joint attacks
1. In order to launch an attack with your allies, you will have to decide who will be giving the orders to the allied troops first, let's call this player "host".
2. Once you have settled on a host, all other players should send units to the host with the mission "Defend ally", as explained above for joint defense.
3. Once all the troops are in position and defending in the Tambo of the host player, the host is to select and add the allied troops to the attack order via the travel orders window, by clicking the "Allied troops" tab.
Note that you cannot select single units from each allied troop, only selection of entire troops is possible. For example, if a troop consists of 100 jaguar warriors, 10 atlants, 5 ek chuahs and 3,000 lancers, only the entire troop can be selected:
To add his/her own troops to the allied troops, the host must click on the Units tab in the travel orders window, and select units for the joint attack.
4. Press the send troops button start the attack.
When joint troops are on their way to hit a target as ordered by the host, all the players who shared their troops will be able to monitor the troop movements at any time through the tambo window, where also the target city and the target player are displayed:
Should any of the participants disagree with the intended mission, they can any time recall their troops by pressing the recall button, in which case the joint attack will automatically be canceled.
The attack protection rules that apply for one to one attacks, in the same manner apply to joint attacks, namely:
a) it's impossible to attack/spy on another player if there is a 10 times difference in their respective scores.
b) 12 hours protection from repeated attacks in case of 75% score difference. This means that when attacking with joint troops, the score of the joint troop is considered to be equivalent to the score of the strongest player who participates in the attack, including the score of the host.
Example: Player A (the host) has 100,000 points; player B (50,000 pts), player C (200,000 pts) and player D (95,000 pts) participate in a joint attack. When launching the attack, the limitations for the player C (being the strongest player with 200,000 pts) will apply to the entire allied troops.
Attack protection ("Pakal" items 
Note that if you activate the attack protection, you won't be able to receive support via tambo. The same is true in the reverse case: with the attack protection activated, you cannot send support to other players' tambos.
When multiple players take part in a battle, both on the attacking and the defending side, there is no preference as for who fights or takes damage first; all players are involved equally, as per the rules of one-on-one battles. Thus, two players attacking with 10 lancers each is generally equivalent to one player attacking with 20 lancers.
If a battle with multiple allies on the attacking side is won, the loot will be distributed according to the strength of each troop contributed to the battle. Thus, the stronger a troop, the more loot its owner will be able to collect:
When allied troops return to the tambo of the host, they don't leave their respective loot share in the city of the host, but preserve it till they are called or sent back to their city of origin. The only exception is the host's troop, that upon the return from a joint attack leaves its loot share directly in the host's city.
If some of the troops are not called/sent back, but sent again as a part of a joint attack, they will use the resting cargo capacity (if and as long as available) to carry their loot share.
If no cargo capacity is left, no resources can be pillaged; that part of loot will remain in the defender's city. Note that the cargo capacity is not combined for the entire allied troops, but applied to each of the participating troops separately. Neither the host nor any other participant will receive a resource surplus if another participant has not enough cargo capacity to carry their respective loot share.
Nahuals and Amazon Warriors: these units will not be divided between the players who participated in a joint attack, but will join the army of the player who has sent the strongest troop.
When raiding barbarian camps through the tambo, it is always the host who receives an amber stone. Also, it is only the host who will get discounted his daily raids, while other participants will not lose their 5 free daily raids; the loot, however, is always distributed proportionally to the strength of each allied troop, as described above.
4. Tambo: further aspects
The tambo capacity is defined as the number of troops that a tambo structure can hold. The maximum tambo capacity is limited to 15 allied troops:
One troop may consist of several units: for example, a troop can be as large as 1,000 jaguar warriors, or it may consist of 1,000 ek chuahs and 100 eagler warriors, etc. In order to be counted as a troop, all units must be sent together.
Each tambo level allows stationing/receiving one allied troop. Thus, the higher the expansion level of the tambo, the more allied troops can be stationed/received.
Allied troops: one troop per player per city (per tambo)
- Each player can send only one troop per city (as defined above, a troop may consist of multiple units). To send a second troop to the same city/same tambo, the troop already stationed in that city must be recalled first. This means, that you can only house one allied troop of the same player at a time, and vice versa.
- It is possible to send support to several cities of an ally at the same time: for example, you (player A) can send a troop out of your city A1 to the city B1 of your ally (player B), then another troop to his/her city B2, one troop to the city B3, and so on.
- There are no limitations as to the type of units that you can send through the defend ally option: even if a player cannot recruit certain units on his/her own, they can still receive such units through the tambo.
Generally, each allied troop will maintain its own stats and bonuses, and will not adopt the stats/bonuses of the host, i.e. of the player who receives allied troops at his/her tambo. For example, if a player activates the fire feast (>100% strength), the strength bonus will apply to all his/her troops, including those stationed outside his/her city at another player's tambo. Also, note that this strength bonus will apply to the troops of that player only, not to any other troops stationed at someone's tambo. Only units speed and corn consumption depend on the host player.
a) Factors & stats determined by the troop owner (i.e. player who sends support):
Upon arrival at the tambo of an ally, the bonuses of the troop owner (sender) still apply to his/her troops:
- Stamina: is determined by the Temazcal level / any other stamina bonus, if available, of the troop owner.
- Strength: is determined by any strength bonus (Kan scepter/Balam blessing; fire feast; Dwarf pyramid) of the sender.
- Cargo: any cargo bonus available to any allied troop is a bonus activated by its respective troop owner.
- Luck: each allied troop has its own luck factor (determined by the Stele, any luck bonus if available, and a random factor) of the troop owner.
- Ahau items (survivors 30%/50%/100%): in case the troop owner activates an Ahau item, it will be valid for all his/her troops, including those outside his/her city while defending his/her allies. However, when activating these items, they apply to the troops of the player who activates them, not to any other troops of other players stationed at the same tambo.
b) Factors determined by the host:
- Speed: if the host activates the lightning feast and/or any other speed bonus, all the allied troops will move at the host's speed.
- Corn and stamina: since allied troops consume the host's corn once stationed at his/her tambo, it is only host's corn reserves that may influence the stamina values of the allied troops, in case the host runs out of corn and all the troops stationed at his/her city would over time start to lose stamina.
Battle simulator: Note that when using battle simulator for joint attack simulations, you won't be able to enter bonuses conferred by buildings/researches/feasts of each ally. Only the bonuses of one attacker and one defender can be entered into the battle simulator to simulate battle outcomes.
To prevent other players (from your tribe) from sending you troops, you can activate the tambo block option: go to "user profile", click on the arrow in the dropdown menu, and from the available options select the "tambo block" option:
When the tambo block option is activated, the blocked player will not be able to send you troops via tambo. You may wish to activate this option to prevent other players from using up your tambo levels and thus blockading your tambo, since only one troop is permitted per each tambo level.
Besides, you should take into account that whenever a battle takes place, all the participants automatically receive a battle report, where all troops are listed. To prevent a player from sending you units via tambo just to receive a battle report, you can activate the tambo block option.
- Whenever you send support to another player's city, you must pay corn for both ways, which is deducted from your corn reserves for both ways right at the moment of sending support, just as it occurs in case of any travel mission (attack, espionage, etc.). Thus, when you recall the troop, no corn costs are to be paid, since they have already been paid.
- While allied troops are stationed at the tambo of another player, it is that player who provides corn for all troops. If needed, the player who sends support can also send some corn along with his/her troops, that will be delivered at the warehouse of the recipient.
Battle report: all players who participate in a battle will receive a battle report:
Espionage report: When spying on another player, you will receive information about all troops at that player's city, though you won't know which troops are allied troops and which are his/her own troops. The espionage report will show troops as if all the troops stationed in a city were from that city.
