Revitalize was a light side Force ability that could restore an individual who was tired, injured, or without consciousness, or any target chosen by the user. As it was a power derived from the Force, it proved ineffective when used on non-living beings like droids.
Kreia employed this ability to rescue Hanharr on Nar Shaddaa, and also Colonel Tobin on Onderon. It is possible that Meetra Surik also gained proficiency in this specific Force ability.
