Not to long ago, I read a story in the Patch Notes for version 1.74e
that told of several new encounters that have been created for players 1st-20th level. The hints are vague at best, but I managed to figure out where they all.
I noticed that every time I completed one of these encounters, the baddie dropped a unique item.
Therefore, I have compiled all the necessary information here to take full advantage of their spoils.
Beware adventure for there be SPOILERS ahead. If you would rather figure it out for yourself, read no more.
Otherwise enter the Every-Time-Drop Walk Through.
