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 (with the exception of the Corruption and Crimson). Unlike other Pylon variants, it does not require a nearby NPC to function.

Trivia

 * The tooltip, 'You must construct additional Pylons!', is a reference to the game StarCraft. This phrase has gained some popularity and became a meme around 2005 and 2007, due to its funny catchphrase.
 * In StarCraft, Pylons are a structure that is needed to create buildings for the races of Protoss, a sapient humanoid species from Planet Aiur.
 * This tooltip can also be seen as one of the splash screens when logging into Discord.
