Not sure as I'm still very early with Chalice Dungeons, but you can check reddit for a list of Chalice Glyphs which create dungeons that include a lot of items/gear.
Edit: Beat two bosses from (I assume) optional areas : peace: Haven't fully explored them, yet, though. However, the Chalice Dungeons take up most of my playtime.
Finished a couple of the "storyline dungeons" and I think I'm close to getting that one item which makes Chalice Co-op/Invasions easier.
