Stuck at 58 level :(

Hi, noobie here!

I have a problem with lvling after I've got 58 lvl. No available story quests, no good exp rewards for doing side-quests (even with battle book and gear with XP bonuses)

I feel like I'm missing something.

Thank you in advance for any advices.

Thank you.

Tenebris' quest is good enough.

And where can I find Martin? Don't remember him.
