Imperial Council

The Imperial Council is a gameplay mechanic available to the Ottomans in Age of Empires IV: Anniversary Edition similar to the cards and decks system in Age of Empires III.

Overview

With the Imperial Council system, the Ottomans gain Vizier XP for every unit they produce and for advancing in Age. Upon hitting certain thresholds, the player receives a Vizier Point, of which a maximum of 5 can be earned by default. Building the Istanbul Imperial Palace raises this limit to 8. These Vizier Points can be spent on unlocking the benefits listed below. Level 2 and Level 3 benefits require at least one benefit from the previous level to have been chosen.

Level 1

• Field Work: Spawn 2 Imams at the Landmark Town Center. Imams now passively heal nearby units for 1 hit point every second. They can still freely use their standard heal ability in addition to this.
• Mehter Drums: Spawn 1 Mehter at the Landmark Town Center. Mehters increase the movement speed of units in the same formation by 15%. Note that the units have to be in the same formation as the Mehter, not just nearby.
• Anatolian Hills: Spawn 8 Sheep at the Landmark Town Center and increase Villagers' mining speed by 15%.

Level 2

• Military Campus: The maximum amount of Military Schools the player can build is increased by 1.
• Siege Crews: Allows all siege engines to be garrisoned by infantry units. While garrisoned, a siege engine's attack and setup speed is increased by 25%.
• Trade Bags: Increase the amount of gold Traders collect by 40%.

Level 3

• Fast Training: Increase the training rate of Military Schools by 25%.
• Janissary Company: Spawn 2 Janissaries for each Military School the player owns at their Landmark Town Center.
• Advanced Academy: Military Schools can now also produce Lancers and Janissaries.

Vizier Point

Each Vizier Point up to the 5th one requires an increasing amount of Vizier XP to obtain.

Vizier Point	XP Required
1	60
2	100
3	150
4	240
5	320
6	320
7	320

Vizier XP

Vizier XP is gained either by creating units or advancing to the next Age. The amount of XP gained is roughly dependent on the type and cost of the unit, but there is no direct relationship. When the units are created from a building within the radius of the Istanbul Imperial Palace, these values are doubled.

Note: Building a Battering Ram using an infantry unit provides 8XP regardless of whether it is built within the aura of the Istanbul Imperial Palace. Building a Siege Tower always yields 0XP (likely because it cannot be created from a production building and has no assigned XP value).
