Sage's Healing Orb (E) in Valorant is available for free at the start of each round, but with a cooldown period before it can be used again. It is a critical ability for healing Sage or her teammates.
Step-by-step explanation:
The Healing Orb (E) ability is a signature ability of Sage, a character in the popular first-person shooter game Valorant. Sage's abilities are geared towards healing and defense, with the Healing Orb being her most iconic skill. This ability allows Sage to heal herself or her teammates over a few seconds. Importantly, the Healing Orb costs nothing, as it is available to Sage for free at the beginning of each round. However, it's important to note that the ability has a cooldown period before it can be used again, so strategic use is crucial for maximizing its benefits on the battlefield. The Healing Orb provides a significant advantage by restoring the health of Sage or a teammate, making it a vital tool in Valorant's team-based gameplay.
