Macro Mechanic

These are mechanics used to supplement how fast you can obtain units or research.

Overview
Each race has one or more of what is referred to as a Macro Mechanic, a spell or unit(s) designed to speed up their production, tech, or upgrades. The Protoss have the Chrono Boost ability, the Terrans use the Calldown Ability, and the Zerg utilize the Incubate spell.



Chrono Boost
Chrono Boost is the most versatile of the three Macro Mechanics, as it is capable of speeding up production, upgrades, tech, and Units. It pays for this strength by being the weakest in efficacy. Chrono Boost increases speed by 50% for 20 seconds.



Merc Compound
The Merc Compound can call down any Unit that you have unlocked, provided you have the open Supply and resources. Calling down a Unit costs slightly more than the Unit itself does, to compensate for the instant gratification.



Incubate
Incubate is the most interesting Macro Mechanic, decreasing the build time of Drones or Units. This spell has a varied Energy cost, depending on what's building inside the Eggs it is cast at. Drones cost the least Energy, and higher tech Units cost the most. Incubate increases hatching speed by 50% in an AoE.
