Oases

Oases raise a village's production once its villagers work them.

A village sends villagers (the tribe's tenth unit) as a reinforcement to a free oasis of its 7×7 area once its Barbarians are gone. From their arrival the oasis is worked by the village and gives it its production bonus in proportion to the workers: each worker gives a tenth of it, 10 workers the full bonus. How many oases a village works depends on its Steward's House: 1 from level 1, 2 from level 10, 3 from level 20 (none without it). The workers defend the oasis with their own small defence; when none is left, the oasis is free again.

Raiders take an oasis' own stock: what it produced since the last raid, at most 12 hours of it. The Barbarians of a free oasis come back over time.

The bonus of each kind of oasis is on the All the bonuses in percent → page.
