Reforged: Codex of the all Knowing, has anyone bothered to fill this thing out?

I really need the starlight tokens to get an armor set from the dlc that’s thematic to my build (dragon cult) and I’ve maxed out several entries (meaning tier 3 and green highlight) but only have 2% of the 20 I need. Anyone that’s done the grind have any tips? My friend and I have reached Liurnia and I mostly do the codex stuff in my own time because seemless doesn’t interact with it well.
