Research condition
Available to Ottomans from the Commerce Age*. Research it at Mosque. It requires Millet System.
When to research
Research after Millet System when Yörük reinforcements are part of the Ottoman economy; the six-second reduction applies to their spawn time rather than to all Mosque units. The 150 Wood cost is modest, but its value depends on how many Yörük the player will produce before moving to Grand Bazaar. It is a short timing aid, not a general cavalry upgrade.
Reduce Yörük arrival delay
The Ottoman Mosque research requires Millet System and costs 150 Wood for a 15-second study. It shortens Yörük spawn time by six seconds and leads to Grand Bazaar. The benefit accumulates through repeated arrivals, so research it when the Yörük economy will remain active. It does not directly improve military damage or gathering from unrelated sources.
A six-second reduction to Yörük spawn time
Koprulu Viziers requires the Ottoman Millet System and is researched at the Mosque in the Commerce Age. It costs 150 Wood and takes 15 seconds, then reduces Yörük spawn time by six seconds. The effect improves repeated arrivals rather than the unit's attack or hit points, so it gains value when the Yörük production cycle continues. It is a poor investment if the player is about to switch away from that economy or cannot protect the relevant production.
Plan around Grand Bazaar
Grand Bazaar is listed as the next research in the chain, but Koprulu Viziers only unlocks it; it does not apply the follow-up's effect automatically. Complete the initial requirement and then evaluate the later technology against its own costs and conditions. The Mosque must remain accessible, and a long-term Ottoman plan should compare the shorter Yörük arrival interval with military production that could affect the current match sooner.
