Other function of the Castle is the possibility to hire a knight level 10 in case you have not reached the maximum amount of knights for your account. By using the slider you can determine the amount of simoultaneous attack and support marches that you can send. The options are from 1 to 30;
- Every level reduces the gain of Food by 0.5%
The maximum allowed number of Attacks + Supports Marches is also increased by Hero Items and nation bonuses of some races ( +20% more marches than the Castle workers allows for the current level for Byzantines, Japanese, Persians);
Amount of map objects allowed depending on castle level
The max number of resource mines and coin mines you can own is 5 per city. Castle building level limits the max number from 1 to 5 for each 2 levels upgraded. Note that the maximum amount allowed is the sum of the objects allowed for each castle you own.
Castle lv 1-2: 1 map location possible
Castle lv 3-4: 2 map locations possible
Castle lv 5-6: 3 map locations possible
Castle lv 7-8: 4 map locations possible
Castle lv 9-10: 5 map locations possible
Opportunity to hire an army from Castle, as follows:
| Player level | Price | Army |
|---|---|---|
| 1-6 | Double resource / 25 coins/ 4 stars | 80% up to 400 Population |
| 7-12 | Double resource/ 50 coins/ 8 stars | 70% up to 1000 Population |
| 13-18 | Double resource/ 100 coins/ 17 stars | 60% up to 2000 Population |
| 19-36 | Double resources/ 200 coins/ 35 stars | 50% up to 4500 Population |
The Army number is determined by the Army lost in a Battle as a Defender of a Castle in the past 48 hours (player hires the same type of Units as the ones they lost). When this option is used, all loss records are deleted. When a Castle is overtaken, loss records are deleted.
When a Castle's marches level is set, it applies to all the player's Castles.
Number of Attacks and Supports also applies to all the player's Castles.
A player can't reduce the level of their Castle if the player has more active Marches than the desired lower level of the Castle allows.
