Level 5: Nice. I like this one.
Level 6: Easy. Shit easy. I have defeated levels like this, Gleeok aside, as LEVEL 1 (like BigJoe's original beta and Gleeok's unfinished quest). You're not talking n00bs playing this. I'd suggest toning this up slightly, maybe a bit. Lv. 4 of the Second Quest was harder.

Onto 7.
