Force Strong is a technology that can be researched at the Jedi/Sith Temple in Tech Level 4. It costs 200 Nova, and gives Jedi/Sith Knights and Masters +3 conversion range and Line of Sight. It is available to the Galactic Empire, Rebel Alliance, and Republic. Jedi/Sith Stamina must be researched before it becomes available.
The extra conversion range is useful, but the extra Line of Sight is also a nice addition. When combined with Sight Beyond Sight, this technology will give the Republic's Jedi an incredible scouting range.
"Jedi and Sith Masters gain an even greater range for their ability to convert units, thanks to this ability."
