Anyway, I personally think Vampires are the easiest quests aside from animals and werebeasts.
Werebests are virtually always a naked fool and never transformed and you just waltz in and beat the hell out of them.
Animals are usually predators which are almost always much weaker than the herbivores. I recently got sent to kill a dingo, a lone singular dingo...
Vampires are wussies because you can call them out from a distance and let the horde of peasantry ream them. You personally need not fight 99% of vampires, you just accuse from a distance and wait till they get killed.
The hardest things are:
Bronze Colossus cause virtually nothing can actually slay it.
Necro towers unless you are a vampire. Namely because of the sheer number of zombies often just opening the door lets 4 zombies claw at you in one turn.
Mummies are scary as hell and the armored variant are just hellish.
Finding that damn guy in the sewer, often I end up killing like 3-4 other bounties before I find the real target of the search, if I find it at all.
Also here is neo's patent method to kill bandit leaders.
1. Bring huge army.
2. Set huge army loose upon equal bandit army.
3. Walk behind your guys so that the bandit archers pick them up as targets and thereafter fire at them till target is dead.
4. While they are distracted solo assassinate the bandit leader.
5. If there is any loot nearby that you must have, try to grab it, unless it is near archers.
6. Run like a bitch and leave your troops behind. If they are mobile some may even escape with you. ALWAYS ignore remaining opponents.
This solve most of my bandit camp death issues as I usually died either A from bolts in the initial rush or B from bolts after killing the leader.
Things that seem hard but are not.
Dragons, mainly a horde of assistants is able to disable these.
Hydras, meatshields to distract it while you crack heads.
