Hall of Golems/1.03.25

Dark Dwarf
The Golems are the biggest basic infantry in the game, yet the building that produces them is surprisingly small. The Hall of Golems is also one of the Dark Dwarves two main production buildings, so it's very fortunate that they are smaller than the average building - especially as Dark Dwarves tend to run out of room fast when Siege Workshops start popping up (due to both size and "free space" needed around the Dark Dwarves base in general to accommodate for the large size of the Siege Weapons). As Stone Golems, the basic Dark Dwarven infantry, are very powerful for such a basic infantry, it does mean you wont need many at once to keep up with your enemy. Because of this you wont actually need many Hall of Golems very early on and can get away with as little as just two. However, later on you will find yourself building as many of these as you would with any other race's main production building.
