Buildings
Buildings are needed to create more units or increase your units stats. There are two types of buildings; Bases, which create more units, and Towers which increase units stats. Bases take up more room than towers.
Builder Base
Will increase your maximum builder population by 2. While ever you have less builders than maximum, these will create builders at a speed of one builder per minute. Platinum Builder bases increase Builder population by 4 and will create Builders at one builder per 30 seconds.
Warrior/Magician/Defender/Runner Base
Just the same as Builder Bases but are concerned with the relevant type of unit.
Miner Tower
Increases maximum miner population by 1 and will create miners while ever you have less than max. Miners will collect Platinum and bring it back to the Miner Tower. Platinum Miner Towers increase Miner population by 2, and increases generation speed from 60 seconds to 30 seconds.
HP Tower
Increases the maximum HP of all your units by 7%. 7% may not sound much but remember that this is for all your units. This effect is cumulative. Building another will increase the new value by another 7% (14.49% total) and so on. Platinum HP towers give an increase of 15%.
EP/Pow/Mag/Spd Tower
Like HP tower but for the relevant stat.
Guard Tower
This building will attack enemy units that step within its range and will warn you of an invasion. These can make a great defence at the cost of land which could house another type of Tower. Platinum Guard Towers have increased range.
