Step-by-step explanation:
The student is inquiring about a specific ability from the character Sage in the video game Valorant. Sage's Healing Orb (E) is a signature ability that can be used to heal herself or her teammates. Sage's Healing Orb (E), an ability from the game Valorant, does not use charges but has a 45-second cooldown after each use, allowing it to heal Sage or a teammate once before needing to cool down. As of my knowledge cutoff in 2023, the ability does not work on a charge system like some other abilities in the game.
Instead, it has a cooldown period after each use. Upon activation, Sage's Healing Orb begins a 45-second cooldown. There aren't multiple charges to stack or collect; rather, the ability can be used once and then must cool down before it can be used again.
