| —Age of Empires IV description | ||
The Cistern of the First Hill is an economic landmark available to the Byzantines in the Feudal Age in Age of Empires IV: The Sultans Ascend. It functions the same as a Cistern, in that it provides economic and other bonuses that scale with its water level and can be connected to a Cistern network with Aqueducts. It also grants all non-siege units the powerful Pilgrim Flask healing ability.
Despite the similarities with a standard Cistern, The Cistern of the First Hill does not increase the cost of other Cisterns by +50 stone when built, and it has a separate cooldown for its Akritoi defense ability.
Special ability[]
Pilgrim Flask (Active): Non-siege military units can be activate it to increase health regeneration by 25 per second for 6 seconds. Each unit consumes one flask and has a 45 second cooldown before being able to use another flask. Flasks refill every 30 seconds up to a maximum of 20 active flasks. Six flasks are immediately available when the landmark is completed.- Automatic Pilgrim Flask (Toggled): When toggled on, a unit will automatically consume one flask (if available) when their health drops below 30% of their maximum health
The other abilities are the same as the Cistern.
- Cistern Influence: The Cistern generates a 10 x 10 influence area which cannot overlap with that of other Cisterns, and which provides one of the following bonuses that can be chosen by the player for each Cistern. A building which overlaps the influence zones of two different cisterns can gain multiple bonuses at the same time, but cannot stack the same bonus multiple times.
- Conscriptio (Influence): All buildings within the influence of the Cistern produce military units production rate +20%/+40%/+60%/+80%/+100% faster depending on the Water Level
- Dialecticus (Influence): All buildings within the influence of the Cistern have +30%/+60%/+90%/+120%/+150% faster research rate depending on the Water Level
- Praesidium (Influence): All buildings within the influence of the Cistern take -5%/-10%/-15%/-20%/-25% damage depending on the Water Level
- Akritoi Defense (Active): When activated, all Villagers within a 9.5 tile radius gain a spear attack with +1/2/3/5 damage per Age and gain +2 melee and ranged armor for 30 seconds. Villagers do not need to remain within this radius to maintain this bonus. Additionally, Villagers that enter the radius after the ability has been activated will gain the bonus for however long is left on the timer. This ability has a global cooldown among all Cisterns of 150 seconds after it is activated.
- Irrigated (Passive): Villagers within a 9.5 tile radius have +10%/+14%/+18%/+22%/+26% gathering rate per Cistern water level. This bonus is maintained for 20 seconds after the Villager leaves the aura. The bonus does not stack with multiple Cisterns.
