Hut

Huts are the most important building in GambCiv. They provide several essential functions.

Action Points
First and foremost, huts provide you with extra action points. When your turn starts the game starts you at 5 action points and for each hut you own it adds 25 divided by the previous number. Wesnoth drops everything after the decimal point, producing the following sequence:

5->10->12->13->14->[...]->26

Upgrading to a farmhouse will make your hut count as two during the calculations.

Community
The next important function of huts is the community they provide. You can build within 15 hexes of a hut you own. This is much safer and more efficient than moving your leader around everywhere you need to build.

Protection
Lastly, huts will protect the hexes directly adjacent to them. Enemies will not be able to build (or destroy your things) in these hexes until they capture the hut.

Upgrading to a watchtower doubles this range.
