The Protoss Guide
Protoss units are expensive and powerful. Your job is to spend them efficiently — and Chrono Boost everything.
What Makes Protoss Different
Protoss units have Shields — a separate HP bar that regenerates out of combat. This means Protoss armies are most effective in the first engagement of a fight and much weaker in prolonged skirmishes against units with persistent HP regeneration.
Protoss also has Warp-in: after researching Warp Gate, all Gateway units can be warped in anywhere near a pylon on cooldown rather than trained in a building. This means having more pylons across the map lets you warp in reinforcements in the field.
Chrono Boost is the economy tool — spend Nexus energy to boost a building to 150% production speed. A Chrono-boosted probe is 50% more efficient; a Chrono-boosted upgrade finishes faster at a critical window.
Chrono Boost
Chrono Boost gives 50% production speed for 20 seconds on 50 energy. Every Nexus starts with 50 energy — the first Chrono should go on the Nexus for probe production before any gateway units exist.
- ✓ Early game: Chrono Boost probes at the Nexus
- ✓ Opening rush: Chrono the first unit out of Gateway (Zealot/Stalker) for aggressive timing
- ✓ Pre-fight: Chrono Blink/Charge/Storm upgrades to hit the timing window before your push
- ✗ Don't let multiple Nexuses sit at max energy — that's free Chronos wasted every cycle
Shield Battery
Shield Batteries restore shields on nearby Protoss units and buildings. They are one of the strongest defensive buildings in the game — a single Battery at the natural can hold early aggression that would otherwise kill a Terran or Zerg outright.
In the early game, building a Shield Battery at your natural before your third Gateway is often better than the Zealot you could have built for the same cost.

Matchup Notes
Protoss vs Terran
The core question is Robo (Colossus) vs Twilight (Storm). Colossus is safer; Storm is stronger versus bio but requires APM. Avoid getting EMPed — keep High Templar spread and your Colossi out of Vikings' range. Watch for 3-CC macro builds going into late-game BC or Raven.
Protoss vs Zerg
Protoss needs to be aggressive in the mid game or Zerg drowns you in units. Timing attacks with Colossus + immortal, or heavy blink Stalker, keep Zergs from saturating a third and fourth base freely. Watch for all-ins on 2 bases — Spine Crawler forward + Ling/Bane/Roach.
Protoss vs Protoss
PvP is decided early. Proxy Gateways, 4-gate pressure, or double-Stargate openers can end the game before 5 minutes. Scout with your first probe; if you see a single Gateway and no Nexus, you may be 4-gated. Shield Battery at the natural entrance is standard.
Common Mistakes
- Not Chronoing the Nexus — probes fall behind immediately
- Forgetting Warp Gate research — warp-in is strictly better than train
- Over-chrono upgrade buildings and under-chrono probes in the early game
- Running Colossus into the middle of the fight without Stalker body guards (Viking bait)
- Warping units one at a time instead of all gateways simultaneously in a fight
- Not spreading pylons — a single pylon snipe kills warp-ins in an entire area
