Questions this episode answers
Why is +1 Infantry Armor so important for Terran in TvZ?
A Lurker spine deals 20 damage. With +1 Infantry Armor from the Engineering Bay each hit on a Marine drops to 19, so a Marine (40 HP) survives two hits instead of dying to them, and your infantry lasts much longer in a fight.
Missile Attacks or Carapace first for Zerg against Protoss?
If your army is Hydralisks and Lurkers, Missile Attacks from the Evolution Chamber comes first. It raises the damage of your attacking units directly, so you kill Zealots with Leg Speed before they reach your army.
What does EMP Shockwave do against Protoss?
EMP Shockwave, researched at the Science Facility, removes all shields and energy in its area. Fired on a Protoss army it strips the shields and empties Arbiters and High Templar, making them easy targets.
What is the most important early Protoss upgrade in PvT?
Singularity Charge at the Cybernetics Core, which extends Dragoon range. Dragoons can then fire from outside Marine range and approach sieged tanks more safely.
Full summary
Episode 6 is a deep dive into upgrades and research across the main matchups. It is for beginners, intermediate and competitive players who want to understand how the right choice and timing of weapon, armour, speed and spell upgrades works as a hidden multiplier on army strength in the mid and late game.
Grast explains it through three pro games. In Best (Protoss) vs Last (Terran) on Fighting Spirit he stresses Singularity Charge for Dragoons, Siege Mode and Spider Mines for Terran, Zealot Leg Speed, an early Observatory and EMP Shockwave. In StarLT (Zerg) vs Bisu (Protoss) he looks at the Forge Fast Expand and at StarLT's decision to research Missile Attacks at the Evolution Chamber instead of Carapace, to raise Hydralisk damage against Zealots before moving to Defilers with Dark Swarm.
The third game, In_Dove (Terran) vs CutePane (Zerg) on the Korean Fish server, opens with a Boxer-style Bunker Rush and shows the episode's key number: +1 Infantry Armor cuts a Lurker spine from 20 damage to 19 per Marine, which noticeably improves their survival. Grast closes with a macroMacroRunning your economy and production: constant workers, supply, new bases and spending your money. point: build more production buildings instead of queueing units.
