This Did You Know comes from Cor Pethroni member Rufustus, a burglar:

The burglar’s distract ability, Riddle, is a great way of pulling a single enemy out of a pack to make the fight more even for a soloing burglar. When a burglar poses a riddle to an intelligent enemy (not Beasts, Insects, or Creatures of Nature), the enemy will become distracted for 30 seconds (or until damaged) as it tries to solve the riddle.  So, how do you use this skill to your advantage?

First, approach the group of mobs until they notice you and start attacking.  Second, quickly distract the mob you want “mezzed” for 30 sec. 

Third, run away from the others until they stop chasing you.

Fourth, run back and stand just out of range before 30 seconds are up.  Finally, when the distracted mob gives up trying to solve the riddle, it will come after you, but the others will stay put, milling idly around with glazed looks on their faces:  “Hey, where’s that other guy running off to in such a hurry?…  ah, who cares.”  You can quickly and easily dispatch the single enemy, and then Riddle the next one!

Rufustus believes that knowing this little trick will make some solo quests a LOT easier for novice burglars.  It is also useful for questing in a group with a burglar, when that group is attacking mobs above their level range.

Happy burgling!
