Cave

Back: Buildings

Purpose

In the Cave spies can be assigned to scout enemy cities. You can also store Silver here to pay for their services. The higher the level of the Cave, the more silver one can store. Once the Cave is completely expanded the limit is removed.

Requirements

• Warehouse Level 5
• Senate Level 9

silver stored in the cave is removed in 2 ways

1) you use any amount (min 1000) to spy on another city

2) Silver will be removed if you are spied upon by another player and the player spying upon you does not use more silver then you currently have in your cave*

• Note: If cryptography is researched, then opposing spies will 'have it 20% harder'

Building Levels

Times are subject to change due to Senate Level * [1]
