- track the relative difficulty of quests in the Journal (relative to player level), so players won't keep running into encounters which they aren't meant to be doing yet.
For example, Lae'Zel wants to find her fellow Githyanki. But once you get there, a fight starts. If you're not Level 4 yet at that point, you are very likely to die.
This happens with a lot of quests that are simply too high level but easily reachable by the player anyway.
