Gadaa System
Gadaa System is an Industrial Age Ethiopian Mountain Monastery technology requiring Oromo Alliance. It increases unit hit points and damage by 5%, raises Villager and Abun gathering work rate by 5%, and improves Mountain Monastery auto-gathering work rate by 5%.

Effect & research conditions
Research costs 500 Influence and takes 20 seconds. The effects span the army, two worker types and the Mountain Monastery’s passive income. Oromo Alliance is a prerequisite, so this is part of a late-game progression rather than a first-step upgrade. Check which resource the Monastery is set to generate and whether Villagers and Abun are actively gathering before valuing the economic portion.
Research condition
Available to Ethiopians from the Industrial Age. Research it at Mountain Monastery. It requires Oromo Alliance.
When to research
Research when the Ethiopian army and economy can use several of the bonuses at once. The military increase helps units already fielded, while the gathering changes need active workers or a functioning Monastery. Influence is also used for other Ethiopian choices, so compare this upgrade with the next unit or alliance purchase.
Use the military and economy effects together
Gadaa System gives modest improvements across several parts of the Ethiopian force. Its 5% unit health and damage apply broadly, while the 5% gather-work increase is specific to Villagers and Abun and the 5% passive-work increase belongs to the Mountain Monastery. The research is most efficient when all three parts can contribute. Secure the prerequisite Oromo Alliance and keep the Monastery active; otherwise some of the technology’s value is left unused.
