Hi all,
After hours of tedious backtracking and forum-referencing, I finally managed to finish the Dvalin ion9 quest for the first time this evening. I referenced this 2014 post to find out what he would accept: https://forums.kronosaur.com/viewtopic.php?t=6662.
According to that post, the quest was made easier and the weapon was buffed. Along the same lines, I think it would make sense if Dvalin accepted certain Corporate Command items like high-level Chimeric equipment.
Cheers!
Minor suggestion: Make Dvalin accept CC items
