DT Rush

A tech rush that skips standard openings to reach dark templar archives as fast as possible in PvT. If Terran has not built an engineering bay for turrets and has no comsat station for scanner sweep, the invisible dark templar walk into the base and end the game outright. Even if Terran has detection, every scan used on DTs drains valuable comsat energy.

Build citadel of Adun immediately after cybernetics core, then templar archives. Produce two dark templar the moment the archives finishes and send them to Terran's main and natural simultaneously. The timing window is narrow — you need DTs on the map before turrets complete.

This build is strongest against greedy Terran openings that skip early engineering bay, and on maps where scouting Protoss tech is difficult. Transition by merging DTs into archons and adding gateway units for a standard army. Weak when scouted early, as Terran simply builds turrets and comsat, leaving you behind on army count with expensive tech that provided no damage.
