I stick with Apophis, since the first poll.
Namely a “convert elemental damage to void damage” spear.
Very happy the idea made it in the list.
That said, both Lost Refuge and Osprix are very acceptable themes, because they fit in with the story and I woud like uniques to have links with the lore.
I mean, they are not quite as good as Apophis, but still good ideas.
