Yeah it sure is strange that there are a handful of fights in Darion that are much harder than everything else:
Enema kid - this sucks because you have no indication that it will be a hard fight.
Staff of Destruction - at least you can see that it is level 14 so you can tell whether you should go for it. Personally I would leave it alone until after Kordar.
Troops guarding King's Tent - a stack of 70 Horsemen? Yeah, that's doable at level 5.
