Hey guys, after several trial and errors, I can say that scout with hallucination works best. Although it canny last forever or stay forever, it’s far safer and less costly method to scout.
Even if we have observer to use, you still need to build robotic facility to get it. What’s more it can be shot down easily if they built detectors or missiles turrets and photon cannons.
Next in our Protoss build order, Gateway and Cybernetics Core are our staple food. So why don’t we exploit something from the existing objects?
The key idea is simple, hallucination costs only energy from Sentry and the research cost… Get a sentry from gateway or a couple of it. Then research the hallucination from cybernetics. One sentry can casts two hallucinations when it’s fully charged. Each hallucination lasts a minute it’s good enough to get the information you want. You can let the hallucination die anyway, its just energy, not your economy.
Phoenix hallucination works best because of it’s speed. But our enemies will start to think why the he’ll we waste a Phoenix just to scout… No one cares
