Elemental Temple/1.03

Temples
Elemental Temples allow the player who converted it to produce any of the 4 Elementals from it. As each Elemental have their own unique role, as well as differing costs, capturing an Elemental Temple can be a great asset to you. Of course, you just need to keep it protected - which is not exactly easy considering that Temples tend to be found in the middle of the map. However, these days there are quite a few different ways to get ahold of an Elemental. But, other than the Nature spell "Elementalismn", there is no other place to get a hold of all 4 Elementals together.

Trivia
