Sacred Pool

Ssrathi
This building is a God send, quite literally, too. The Sacred Pool powers up the Snakepriests by giving them a total of +6 range, as well as 300% mana regeneration. This allows the Snakepriests to out-range un-garrisoned towers, rapidly heal themselves from the few things that do reach them and proceed to sweep the enemy off the map. The six researches that achieve all this are expensive in crystal, though. But fortunately, the Ssrathi don't make much use of their crystal so there's little competition as to what gets to consume it. Aside from those researches, the building has no other purpose. So if it ever gets destroyed after you've done all the researching from it, then you wont even need to rebuild it. As you would have come to expect by now, this building is also quite small.
