Pylon
The Pylon is the Protoss supply building and the primary source of the Psionic Matrix power field. After warping in, the Pylon is surrounded by a circular field of the Psionic Matrix, providing power to nearby structures and enabling units to warp in on demand from Warp Gates within a radius of 6.5. Each Pylon also provides 8 Psi supply points.
Almost all Protoss buildings must be initially warped in on the map within the Psionic Matrix. If the Matrix is removed (due to, for example, the destruction of a Pylon), any structures in the area will become unpowered and cease to function. It is therefore important for Protoss players to ensure that their infrastructure is powered by sufficient Pylons to prevent opponents from shutting down a large portion of their base with the destruction of a single, critical Pylon. However, if a building is a prerequisite for the construction of other buildings or units, the prerequisite is still met while the structure is unpowered.
2 Pylons cannot power a building
Note that buildings need to be powered by a single Pylon, they cannot use the combined fields of two or more Pylons to be powered.
PROTOSS – THE WARRIORS OF AIUR
HONOR. WISDOM. TRADITION.
In stark contrast to the adaptable Terrans and the ferocious Zerg, stand the rigid, tradition-minded Protoss. With their psionic abilities and advanced technology, the Protoss have long considered themselves the most powerful species in the galaxy. This people’s greatest asset is the tenets of their primary religion – the Khala – whose tight framework demands dogmatic adherence.
Protoss Buildings
Another outstanding technical achievement of the Protoss is to teleport their buildings over long distances from their home planet Aiur to the most remote parts of the galaxy. This is done by converting the buildings into energy and dematerializing them within the psifields built on the outposts.
