Knowledge
Knowledge books, and the cap per class.
A knowledge book is read to raise your knowledge for one class; reading it uses it up, and the game asks before it does. Each class has a maximum knowledge, and past it the game refuses with the class named (“You have reached the maximum knowledge for …”). The cap is not shown ahead of time; the refusal is how you learn you are at it.
Knowledge books
| Item | Type | Where from |
|---|---|---|
 Basic Knowledge | knowledge | dropped by  Dragon |
 Expert Knowledge | knowledge | quest reward: Dragon Collector |
 Master Knowledge | knowledge | quest reward: Relic Unleashed |
 Novice Knowledge | knowledge | no shop, recipe, drop, quest or chest lists it |
From the update notes
What the developer wrote when this was added or changed, newest first.
Return of the Casters pt2 , 0.4.53
The goal for adding this small introduction quest is to make it clear that choosing a class is an opportunity rather than a permanent commitment. EO fully supports players to switch between classes at any time without losing the progress, levels, knowledge, skills and hotkeys they have already earned in previously trained classes.
Hall Of Pain , 0.4.51
A researcher near Voidsite WA-1 has found something strange hidden deep in the forest. Between the trees is a secret passage leading to an unknown area. Inside, there is an odd chest giving off a low humming sound.
The researcher was too nervous to go closer and asks you to investigate instead. This way, players who missed the Dark Ticket giveaway now have a reasonable alternative to obtain it as well.
Map Upgrades , 0.4.49
A dispatched group of Aeven researchers has discovered a sudden, unstable new type of void breach west of Aeven. Their portal is, once again, too unstable for them to enter.. but players can. The team is calling for help to investigate.. But what lies within this anomaly remains unknown. Teamwork may be the only way to uncover its secret.
Item System Upgrades , 0.4.45
Holding back on using this systems until now has proven to be a good decision, as two years of playtime have made it clear which critical things are still missing in this system. With that knowledge, the system can now be slightly adjusted, within what's still possible, to address those gaps and improve what is truly needed at this stage.
Mounts , 0.4.44
- CLASSIC Quest: Bat Research (L3)
He needs someone braver to collect 5 Bat Wings from the Aeven Mines. Upon return, he praises your reliability and gives you some Eons for helping his research.
