How to complete the final step in the Path of the Striker Quest - Zavala’s Challenge.. or Step 8. Basically you need to generate 7 orbs of light, 3 different times using the Fist of Havoc during the same strike. Not going to lie, it’s a bit of a pain. But here is how I did it. 1. Select the Will of Crota strike on Earth. 2. Have Bad Juju and Helm of Saint-14 equipped (or any helmet with the perk for gaining super energy by killing minions). This allows you to get your super quickly. 3. Right when you spawn, get on your sparrow and haul a$$ to the first encounter! Try to get there before your fireteam. This allows you to kill as many enemies as possible to gain super energy right away. 4. Once you are supercharged, head over to the spawn where numerous stealth/invisible vandals appear on the right side doorway and drop your Fist of Havoc. This should be a guaranteed 7 orbs with all of the stealth vandals and major vandals in the area. 5. After you get 1/3 complete, look around the room to collect any possible orbs that your fireteam has created. If they haven’t created orbs, keep killing with your bad Juju to get your super ready for part 2/3. 6. For 2/3, you will be using your Fist of Havoc on the mass number of fallen walking down the stairs that separate you from the next encounter. Just wait for the laser beams to deactivate and drop your Fist of Havoc. Boom! Guaranteed 7 orbs. 7. For 3/3, enter the next encounter outside and kill everything you see with your bad Juju. BE PATIENT, and wait for the second Fallen Sciff to arrive. 8. When the second Fallen Sciff arrives, drop your Fist of Havoc just as the enemies are landing. You should be able to get 7 orbs with ease. Those are all of the tips I have. Hopefully this helps some fellow Titans on completing this frustrating part of the Quest. Feel free to watch the video above on how I completed this. I ended up doing 4 sequences where I generated 7 orbs during this run. The Omnigul strike is definitely the way to go! Enjoy! P.S - don't quit out once you get all 3. You still need to complete the strike to compete the Quest.
