Forge

The Forge is a structure in the Protoss Tech Tree, which requires a Nexus before it can be warped in. The Forge is the research center for Ground Weapons, Ground Armor, and Shields upgrades. It also unlocks the Photon Cannon.

Like most Protoss structures, the Forge can only be warped in at a location powered by a Pylon. It can only research upgrades while it remains within the range of the Pylon, otherwise it becomes unpowered and cannot function. An unpowered Forge still allows the creation of Photon Cannons.

Because it unlocks the Photon Cannon, the Forge is a central part of Cannon Rushes. If a player builds a Forge before a Gateway, that is often a sign that a Cannon Rush is underway.

In PvZ, Forge Fast Expand is a common opening and involves a Forge being constructed as the first part of a wall blocking access to the natural in order to unlock access to the Photon Cannon for defensive purposes.

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.
