Gravity Well is a Crowd Control ability that Astra can instantly activate by targeting a Star that she has placed on the map. A Gravity Well will form on activation, pulling any agents within its radius towards the center. The pull effect can be resisted by inputting movement commands to move away from the well's center. The pull can interrupt spike defuse attempts if it pulls the defuser out of defuse range.
After a short duration, the well will then explode. Any agents still within its radius at this point will be made Vulnerable.
