E.2 Ways of obtaining a spell
There are three ways of obtaining a building in Populous.
Firstly, if you have that spell unlocked, you will start the level with it. Online, if that spell is avaliable in the restrictions, every player will be able to use it.
Secondly, worshipping a vault of knowledge in the campaign will unlock that spell permanently. This is the main way of obtaining spells when playing the singleplayer.
Thirdly, worshipping a stone head, gargoyle or obelysk will grant you one shot of a spell - it is not permanent, you can only use it once, since only vaults of knowledge will unlock spells permanently. When you have only one shot of a spell, that spell will appear on a grey square, with a red charge dot, on the SPELLS PANEL. In case you had already discovered that spell, but get one free shot from a stone head, the only thing that changes it that the charging dot will be red instead of blue.
After worshipping the stone head, you got one shot of the spell landbridge. The square is grey and the shot charge is red, because you got it from a stone head, and can only use it once.
After worshipping the stone head, you got one shot of the spell landbridge. The landbridge icon will get out of the stonehead, and will go to your spells. Watch the image below.
