Strix's stealth can make him harder to track, so toss your Sensor Drones out where you expect him to be and reveal him to your team. If you run the Booby Trap talent, the explosion of your drones can disrupt his aim or throw him off of high ground.
Unless recently killed, you can usually count on Luna to be somewhere near the fight, and for Io to be standing near her. Use your Shock Pulse on Luna for a free bounce between them. This might not apply if Io is using the Sacrifice talent.
