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.
