What level can you access nodes?

[Kirgar]

IIRC the new level nodes become available when you're 2 levels bellow - so you can see lvl 10 once you reach lvl 8, lvl 15 nodes once you reach lvl 13 and so - if that's what you were asking about.

Your thinking of the Disciple of Hand. For a level 10 node that has level 6 to 10 items you need to have level 6+.
