[QUOTE=coldreactive;2625790]Harvest mirror apples, other EXP Boosting base ingredients... get your Heat of Battle II buff on at all times.... Once you hit level 50 in one class, you also get a permanent 50% Increase to exp from FATEs. I'm sure you can solo any of the boss fates if they have failed twice recently. (Save for The Eyes Have It, which is why it has a super long respawn time.)

Battlecraft levequests are for your battle classes (Rogue, Ninja, Monk, Pugilist, etc.) The level 1 ones can be found in the starting cities if you can't find them out in the open world.

I know all that except the boss fate part i was asking which leves in general are worth it in exp as most ive seen are crap exp vs crafting exp.
Also what happens to major boss fates if you fail them twice ive seen nothing happen to them they stay just as hard.
