Sage's C ability helps by blocking off areas of sites but can also help to get off angles on their opponents. Her Q ability, "slow orb" is something she can throw to slow down the other team from pushing onto site making more time for her teammates to rotate to site with her. Sage's E ability, a heal, can be used to heal herself or her teammates. When she heals herself, she only gets around 30 HP back but when she heals her teammates, they get full HP back. Lastly, Sage's X ability, aka her ultimate ability, is a resurrection. Whenever a teammate loses against an opponent, Sage can bring them back to the game by using her ultimate ability. This gives her team an advantage against the other team.
Yoru's C ability is a mirror of Yoru's image that walks forward, and if damaged, it will snap at the opponent that damaged it and blind them and anyone else in site of the decoy. Yoru's Q abilities is a blindside. It helps by blinding the other team but it can also blind his own team so it's important to communicate when you're going to throw the blind. Yoru's E ability, is a teleporter that Yoru can use to get out of situations. He can place it at any time during the round but the downside is that he has a time frame for how long he can use it. Yoru's X ability, "dimensional drift", he will turn invisible and he will be able to use his abilities to flash and confuse his opponents. His ult is good to get intel on the opponents for his team.
Skye's C ability is similar to Sage's healing orb, but unlike Sage, Skye cannot heal herself with regrowth and can only heal her teaammates. Regrowth also has a limit on how much it can heal her teammates and it will only reset after the round is over. Skye's Q ability, "trailblazer", is a dog that Skye controls with her mind that can run out to get information on where the other team is. If an opponent is found, then the dog can jump out and stun them. Skye's E ability is a bird that she can control where it goes and it flashes people. Once the bird is in an open area, or to check corners, Skye can press E again and the bird will flash any person that is in site of the bird, including her own teammates. So similar to Yoru, it's important to communicate to your teammates when you are going to use the bird. Lastly, Skye's X ability, "Seekers", is an intel ability that Skye can release that will find the locations of their opponents. If an opponent is hit by one of the seekers, they will become temporarily stunned, giving Skye's team an advantage.
Omen's C ability, "shrouded step", is a shadow walk ability that acts as a teleporter. He can use shrouded step to teleport across openings and to places that can create off angles. Omen's Q ability, "paranoia", is a projectile that Omen can throw in any direction and if any opponent (or teammate) is in it, they won't be able to see and their ability to hear will also be temporarily replaced by the sound of the paranoia. Omen's E ability is a shadow orb, it acts as a smoke to block vision of the opponents, and can also provide a temporary hiding spot. Omen's X ability, "from the shadows", is a teleportion ability that can teleport Omen anywhere on the map, which is especially helpful for when Omen is running away from opponents. The downside to his ultimate is that he appears as a shadow before he becomes solid at his new location. The shadow can be destroyed by opponents to cancel the teleport.
Astra's C ability is a gravity well. The gravity well, when activated, pulls anyone in the circle inside and makes them fragile. Astra's Q ability is a concuss. Whenever it's activated, anyone inside the circle will become concussed, slowing them and making them easier to get by Astra's team. Astra's E ability, "nebula", is a smoke. When activated, it pops up and creates an astral orb that makes it so opponents can't see through. It also makes for good hiding spots. Astra's X ability, "cosmic divide", is a huge wall that essentially acts as a smoke and a sound barrier. It also blocks anything go through it besides people.
