Yagorath's Caustic Spray deals damage in an area, and will hit your ult drones if she shoots at you. Try to stay out of range or out of sight so it's harder for her to target you.

As a massive hitbox without any shields or walls, Yagorath is an easy target. You can shoot her from a distance for essentially free ult charge.

Terminus's axe can cleave through your shield and will hit your ultimate drones, and his Shatterfall will make it hard to run. Keep at a distance from him at all times if possible.

While Ash is within the zone of her ultimate, your ult is unable to affect her, so save yours for another time.
