Jedi/Sith Stamina is a technology that can be researched at the Jedi/Sith Temple in Tech Level 3. It costs 120 Nova, and lets Jedi and Sith regenerate force power 50% faster. It must be researched before Force Strong becomes available.
Like many of the upgrades available at the Jedi/Sith Temple, this technology is vital if the player uses their Jedi or Sith to convert enemy units, and pointless if they are used exclusively for combat.
"Jedi and Sith Knights and Masters will regain their ability to convert units much more quickly after a successful conversion once you've researched this technology."
