Energy
From Liquipedia StarCraft 2 Wiki
Energy is an attribute of certain units and structures, which accumulates over time and is spent to activate (some or all of) the unit's or structure's special abilities (spells).
Energy is represented in-game by a purple bar below the health and shield bars (assuming status bars are displayed).
Units with energy generally start out with 50 energy and slowly build up energy over time to a maximum of 200. Energy is passively generated at 0.7875 energy per second on Faster speed (0.5625 per second on Normal speed).
The exceptions to the above are:
- Queens start with 25 energy.
- Ghosts start with 75 energy.
- The Shield Battery starts at 100 energy and has a maximum of 100 energy.
- Infestors have an upgrade that raises their starting energy to 75 (Pathogen Glands).
- Point Defense Drones (now removed) started at 200 energy and regenerated 1.4 energy per game second.
Most spells only cost a fixed amount of Energy to cast. Cloak (Ghost & Banshee) and Pulsar Beam (Oracle) are ongoing spells that cost an initial amount of energy to activate and also drain energy so long as they are active. The Shield Battery & Medivac spend energy proportional to the amount of shields/health they restore.
