I think one of the questions we have to stop and ask ourselves before we get too far here: is it important that every 'theme' progress all the way to the endgame? If so, should we look to do that by adding new items, or by rebalancing existing items and moving some significantly downward into the dungeon? I'm more leaning toward the latter, though I can certainly see space for a few more low-level items, especially 11-15 star ones, in the core game. So, for example, I might rewrite the Hjalmirs to be 2-star, 5-star, and 8-9 star? Increasing stats accordingly, of course. Is that a good way to think about these things?
