I'm doing my first exotic sword quest. Picking up from an earlier stalled quest. I'm on the Essential Elements Step. But, up to now I have been using the Sol Edge. I used it in the Crucible and to kill Ecthar. But, my Essential Elements step want me to get materials for the Void sword and Void kills. What happened? I did try to add the Void sword to the mix before going on Ecthar step. But, the Void quest didn't show up on a visit to Shaxx, so I put it in the vault and went to the Ecthar step with the Sol sword. Now I have this next step as though I have the void sword.
