Vivian WILL destroy your shield, no questions asked. But you have the AoE advantage. Get in there and aim for her feet if she has her deflector shield up. You can hold out for longer than you think if she doesn’t have her sentinels up.

Whenever you're up against a Maeve, your Fireball will be necessary as Maeve is more than able to kill you from a distance. If you're alone with a Maeve and not at low health, you can put up your shield and retreat, or burn her with the fireballs.

The educated Strix player knows not to attack you when you're in Counter. The key to getting him is to fight fire with fire and be as stealthy and sneaky as possible; and be ready to react when he inevitably pulls out his sidearm.

Play as carefully as possible and keep moving. If you can’t try to flank Kinessa herself, try and capitalize on any moment she isn’t targeting you. Damage boosting Talents like Blastflower or Scorn are best.
