Prison/1.03.24

Orcs
Prisons are an unique building for the Orcs in the sense that it doesn't require stone to build. However, the unit it produces, the Troll, requires only stone. Because of Trolls heavy stone cost, which faces competition with the rest of the Orc economy, it can be difficult to consistently produce them. As such, you will rarely have enough stone to have multiple ones in production at the same time, and so, you wont have need for many Prisons in your army. The Slavehorde skill can be useful for maintaining mine-fillers while your Orchold(s) are pumping out Kobold Snipers. Although, the gold cost between the two units can clash.
