Dear Bungie, Being able to pick up the motes needed to damage bosses in Kell's Fall seems random. Just tried final boss. I was able to collect 6 motes, even though they were scattered all over the floor, I wasn't able to pick up more. Died due to refraction and then respawned all the way back at the half way point of the mission and was locked out of the boss room. Please investigate. Thanks!
