What's the fastest way to level a character these days?

Dungeons like they said, as an alternative for waiting in between for DPS you can do your levels Battle Levequests as well provided you have allowances. This can be more useful if there aren't people around doing fates, and the chests you find during them can drop aetherial armor and weapons you can use.

I didn't think you could do a leve while queued for a dungeon/roulette in DF?
