SWTOR Worldboss Codex List
Codexes are a type of lore entry that you can collect in-game - they can come from hidden glowing blue object in the open world, from defeating certain enemies, and from completing certain quests. Some codex entries can be found by all types of characters, while others are restricted to characters who are a certain class or faction.
Almost all codex entries are per-character, except for some of the Datacron entries, which are legacy-wide, and some Planet entries that you have earned a Datacron entry on will also be unlocked legacy-wide. The rest you will need to re-earn if you want them unlocked on your other characters.
