Jedi Knight: Jedi Academy
In Star Wars: Jedi Knight: Jedi Academy there were three levels of Force heal. The first allowed the user to heal, but he/she was required to go into a trance that would be broken by combat or movement. The second level allowed the user to move as he/she healed, but once the user engaged in combat, their concentration would be broken. The third and final level, when the user had mastered Force heal, allowed the user to engage in combat while healing.
Knights of the Old Republic
