I see on quest and special quest it shows the enemy level is this like a reccomended level you should be? I'm around level 20 and haven't tried the middle special quest that usally says enemy Lv.30. Not sure how to tell if I'm strong enough before selecting one since you don't get stronger from leveling your level.
Also are the Avatar Boards that cost gems to unlock worth it? Is there a list or pics of what the nodes are and what they cost?
