Final answer:
In the video game Valorant, Sage's Healing Orb ability heals a targeted ally or herself over a duration of 5 seconds. The reference provided is unrelated to the game and is about real-life healing.
Step-by-step explanation:
The student appears to be asking about Sage's Healing Orb from the video game Valorant. However, the reference provided seems to be a misdirection because it leads to a video of a hand healing in real life, which is unrelated to the abilities of a character in a video game. In the context of Valorant, Sage's Healing Orb ability can heal a targeted ally or herself over a period of 5 seconds. The healing provided by the orb is progressive, restoring the target's health gradually until either their health is full or the healing duration has ended. Please note this information is specific to the game mechanics of Valorant and has no connection to real-life biological healing processes.
