Elder Knowledge’s XP Gain Effect
Elder Knowledge might not be the most directly useful Trait to have, but if you can find it early on in your character’s progression and get it leveled up to 20 as a priority, the return will be well worth it in the long run. There are currently 40 Traits in Remnant: From The Ashes, and 20 levels of each, minus the free point given when you first get the Trait, that makes 760 levels to earn to match the 800 Trait points needed to max out all 40. That’s not including any of the Traits that might come with he new DLC ‘Subject 2923’.
Overall, it is definitely worth finding this early, and you can always use an Orb of Undoing to reset trait points spent here, when you get closer to maxing out the rest of your passive traits and no longer need the XP boost as much.
It is worth noting, that this bonus only effects monster kills. Quest bonus XP, or the Tome’s of Knowledge that grant free Trait points, will not be affected by this. Despite this small drawback, considering you earn the majority of XP killing things, the downside is pretty minor considering the benefits.
How to Find the Elder Knowledge Trait
You can find Elder Knowledge early in a new game, located in the B2 level of Ward 13. Travel down to level B2, go through the first main hallway of that level and then look for the second door/office on your left. Inside this office will be a small tape recorder that you will need to interact with to receive the Trait.
Side Note: The tape recorder is actually the sounds the researches recorded after connecting a Dreamer to the Root, though from what I’ve read through the lore, they weren’t aware of that at first.
