Universal Pylon

The Universal Pylon is a Pylon which is obtained by completing 100% of the Bestiary, at which point it will be sold by the Zoologist.

It can be placed anywhere, and used in any biome NPCs can live in and the pylon does not need NPCs to be near it.

Trivia

 * The tooltip, 'You must construct additional Pylons', is a reference to the game Starcraft.
