Grand Bazaar
Grand Bazaar is a Fortress Age Ottoman Mosque technology that reduces Yörük spawn time by eight seconds. It requires Koprulu Viziers, costs 300 Wood and takes 15 seconds to research. The effect changes the interval for Yörük spawning; it does not directly grant a fixed unit group or improve the Yörük’s combat statistics. Since the technology is reached through a prerequisite, it belongs to an Ottoman Mosque progression rather than an isolated universal upgrade.

Effect & research conditions
Complete Koprulu Viziers before researching Grand Bazaar at the Mosque. Then factor the shorter interval into the timing of the next Yörük spawns. The research duration is separate from the eight-second reduction, and the benefit concerns the affected spawning process. Preserve Wood for the upgrade only if the Ottoman plan expects to use that stream.
Research condition
Ottomans; Fortress Age*; researched at the Mosque; requires Koprulu Viziers; costs 300 Wood; 15-second research time; Yörük spawn time reduced by eight seconds.
When to research
Choose it when Yörük production is part of the continuing economy and a faster spawn cycle will improve a planned timing. It has less immediate value if the player needs a direct army delivery or is not using Yörüks. Compare the 300 Wood cost and prerequisite path with other Mosque and military options.
A later step after Koprulu Viziers
Grand Bazaar requires Koprulu Viziers and is researched at the Ottoman Mosque in the Fortress Age. It costs 300 Wood and takes 15 seconds, then shortens the Yörük spawn time by eight seconds. The research changes the recurring production interval; it is not an eight-unit delivery or a combat upgrade.
Choose a production bonus over an immediate army
The prerequisite and research time delay the return, while the shorter interval helps only if Yörük production continues afterward. If a fight requires troops immediately, use resources on current production instead. When the Yörük route is active, protect the Town Center and Mosque so both the production source and research investment remain useful.
