Training Ground

The Training Ground is a sovereign structure, enabled by stamina training, which accelerates spearmen production.

Each level of training ground on any city's sovereign squares decreases spearmen production time by 5%, unless otherwise noted in-game for that square. Some sovereign squares will provide up to an 8% boost per level of this structure. To build or upgrade a training ground on a tile, the owning city must have a sovereignty claim of matching level on the tile, and have achieved all the research prerequisites.
